A

Yeah, whoever misses us, they can watch the recording, so I'm going to go right forward with the concept of file simplification. So the last few weeks we've been spending a bit of time on getting reoriented and and set up in free CAD to have effective, workflow so we'll this is especially for you and for anybody who's doing the work. Is we hit a certain point? Well, first of all, before we go there, though, as on an agenda here, will for you especially what we do.

A

Every time is kind of review our team numbers so I want to go through that a little bit. If you look on the front page, there I'm going to share my screen here, so you can see what I'm looking at. So, if you take a look at that, here's here's the meeting agenda. That's the document, sorry that I paste it in yeah I pasted that in here, that is one more time.

A

This is the intro slide, so we keep an agenda every week and this is posted on a on a working team meeting page on the wiki, so just as an overview of the current effort, we're tracking the progress with with this graph.

A

Here, everyone fills a weekly timesheet and we're hovering at kind of like the I see here this that's the last week here this week here last week, so people have either haven't logged or haven't done the work, but we're hovering about like nine developers putting in ten hours per week on average we're actually averaging more than ten per average.

A

Some people bring that average up like, for example, myself I, don't do ten I do more like 50, so that these numbers tend to go up a little bit, but the red is the developer hours per / 10 so so like at the peak we're getting about 150 hours, that's almost four full-time equivalent per week. So that's that's!

A

That's our very dedicated development effort that happen and we're tracking this to learn and- and you see kind of we plateaued here and I- think that's one of the growing pain issues here as we're trying to get the processes streamlined and people clear and really addressing some of the gaps on unfree CAD teaching that we have to do on a team. As far as on the home front here, what you see here in upper right hand corner that's the prints from the D 3d, so I've been optimizing, the print quality there.

A

So these are actually new parts for the next set of 3d printers, but pretty much got the print quality perfected. There's one issue: I need to still resolve, and that is on the automatic bed. Leveling part that works awesome in the sense that the printhead follows the bed based on probing of the bed height that is automatic. But when it, when the printer starts up, it tends to sometimes it tends to start at the wrong place like like either 1 millimeter above or below the intended place.

A

So I just got to solve that thing, but but the cool part is that we're starting to print parts I'm going to be getting about six or eight of these machines up for producing parts for the next production for the next next workshop. Ok, if we look at the agenda as far as the three CAD documentation, io made a few nice videos, so you can actually click a link on that I, like his style, get I. Oh yeah I like the style like IO your ear on a call here. That is correct.

A

What you have done and like the navigation, stuff I remember when I first started, I just couldn't figure it out like it was so counter intuitive, and it's like makes you want to give up like how do you? How do you navigate or even just select basic things, but then after I figured out I kind of totally forgot about it? That's even an issue for anybody, but it's true.

A

We wanted to document those basics that we tend to skip over because for me it's like I forgot that there was such a pain to get used to it. But you're kind of reminding me that and it's true, a new personal will be confused by it. Okay, so please review BIOS videos. I just watched the first one I got to watch the two other ones, but that's that's pretty good, and that goes right into the the file simplification process, the workflow for what I have here on.

A

So there's a page on the wiki. It's simply called file simplification. Let me paste it in and I'm going to go through that. This is the main topic of workflows, how we're really getting into product data management like right now, the d 3d cad file for the 3d printer is huge. You can say it's unworkable when it comes to this standpoint of design with it so I'm going to go through how I'm actually going to go into edit mode here and go into this document. Well, let me stay here for now.

A

Actually, so the idea here is that the files right now for D 3d are large. We want to simplify them. We have a, we have a spreadsheet, so this is the part library spreadsheet of all the parts. This is on a d3 part library page, but what I've done is taken. So, let's so, let's take a look at some of this here. These are all the individual parts for the 3d printer and there's 40 parts.

A

That's the unique part count what I've done what's what's notable here what's worth looking at is column number K and that is using a file simplification process to get you much much much reduced file sizes compared to the originals like here, we've got, let's see, what's a good one like say the motor printed piece, you know say it's 100k.

A

Here it was like this is this: gives you an example of a drastic jump, so this is the version history on the wiki of the save the motor, the universal axis motor side, free printed piece, it used to be say: 200, K or 100 K, 200 K put them, drops it down like a bomb into a canyon just like 5 K. So how do we do that? This is what I'm going to talk about today and you get a file, that's still workable. You can work with it while allowing to do that very very fast.

A

It retains all the critical geometry elements while avoiding the heaviness of a regular file, and this is what everyone has to do like I was, for example, looking at some professional cut packages how they treat this issue Essos article. How do you manage file sizer and the first thing they said- use simplified files? Well, that's exactly what we're doing so. This appears to be a pretty good industry standard and naturally, you want to make the CAD very friendly to work with.

A

So you tend to go straight to the CAD and work quickly to make new designs like we do the construction set approach, so we want to do all kinds of different designs with the same system, and this simply lets us do that very very effectively. Ok, so let's go through this process. I'm gonna walk you through. So just just for reference. What's the baseline file size of freecad parts? Well, it's just a few K for a block. You know like I. What I did here was just look at blocks and multiple blocks.

A

How does memory grow in a file? Well, a simple, very simple file like here like this 2 4 6 hexagon here or cube there like 7 K, 5, K, 2.8 K, some learning cereal, when you, when you add, add parts to it. You know like this: whatever is five blocks end up being 22 K, then you can simplify a little bit. You remove the sketches. So what we're doing in this whole process were to get the absolute absolute minimum file size.

A

We can move sketches while retaining like say we're using a real file, but we say one version of the file that has all the sketches in it underlying sketches and one without. But one thing I have noticed so here's some of the conclusions like they did primitive solids are about five K each. If you use them by sketcher, if you create them using the sketcher workbench now part workbench actually allows you to create solid. There are one half the memory of sketch sketched solids.

A

So here, let's see where was this via sketcher via sketcher, when I did some of these by using part workbench, you can create solids in there and they end up taking half the memory here. Here's the example two point: eight K in the part workbench as opposed to five point: five K using sketcher. So it's just. However, the kernel geometry kernel works. It's just simpler when you do the part workbench, it's just less memory.

A

So the point is: whenever you try to do a design start with the part workbench biffle, because in a park work but part workbench, you can define as if it's a cube, you can define the three sides XYZ. So, instead of using sketching and extruding a flat shape, you can X, you can start with a solid which ends up taking less memory and then you can do more features like poking holes in it or whatever. You need so lesson one and use part workbench whenever possible.

A

So the second point, the other point here- removing sketches- reduces memory about only about 10 to 20 percent. Well, here we actually have.

A

Yeah 22 K from 25 K we wanted to remove the sketches, went to 22 K, not a lot just 10, 10 or 20% so does generate primitive shapes using part workbench whenever possible. Okay, so let's go to the example of our universal axis. So this is our Universal axis that we use for all kinds of CNC machines, starting with a 3d printer. We enlarge this to make larger machines like 1 inch from the torch table and up to two inch rods talking about rod size here these rods and trots for super heavy-duty machines.

A

Okay. So how do we simplify so this here? The original full detail file is like 6 megabytes unworkable. I mean just unworkable. It's like! First of all, it takes you like 30 seconds to load it up and freecad, at least in my computer, and you can think about if you've got a full full device, full 3d printer design. That's like 30 megabytes, too much, ok. So what we do take take this and simplify to the sorry.

A

You got to study it and understand what are all the critical features so here in this example, I identify the critical features that need to be retained. You need to retain that. There's a motor there there's the various parts that we need. You definitely need a motor. You actually need the location of the plug in the motor, because that you have to pay attention to that. You got the motor piece, you get the carriage piece, you got the idler piece.

A

We need the four holes and I in a in a carriage piece, because that's how you attach the if this is the well. If this were the y-axis, then you can attach things like the x-axis to eat these bolt holes here you can align them so I left that there's nut catcher holes on the end one side, another, that's how you attach say the X to the y axis. So there's a various details and I identified here is like 13 how many 15, decals and stop and so forth.

A

So you can look at the details of what's in there, but if you examine like what, when you're designing a machine like what all are the critical elements, so retain the critical elements you don't care, what's inside, I I eliminate the belt because it takes a lot of memory in it and you know the belt is there and it doesn't interfere with anything? So I did that. So so we calculate the expected memory.

A

If you got like 13 features that this file should be like 65 K, because we're saying that well, each each primitive object takes like 5 K from the first slide here on the primitive objects. Okay, so then I went to the credit extract the critical dimension. This is. Actually, this is pretty cool. I mean go to the drawing dimensioning workbench. We could use a nice instructional if you, if you click on this here, you can get instructions on how to do this, but it's really nice.

A

Actually in freecad you I, took all I did here, was I took the x-axis assembly using the drawing dimensioning workbench I. Just put these three views in here. It's rather straightforward.

A

Just select that in the workbench- and you just start adding dimensions, really beautiful I mean you can add, I mean this looks professional in you know all these dimensions, the bubbles, the bubbles represent all the critical parts that I need to retain so I, basically, in this flat shape, I I mark all the different sizes of everything, so that then I could reverse engineer this, in other words, simplify all these parts from the complex file to the to the absolute minimum file.

A

So let me actually go to the very end here and show you what the actual final product is so on. The left here is this about seven Meg, overall detailed file and then at the end, after doing just those 15 elements, I mentioned before 24 K, there we go now we're talking so you see, I have still have the motor represented.

A

I've got the critical parts represented in exact geometry. This motor is not it's actually very accurate, I mean it's not super accurate, but but the carriage pieces they're absolutely accurate to a fraction of a millimeter. The critical parts like these nut catcher holes, which attach to the other to another axis like if this is the X you attach to the Y using these, so you can snap them together using a circle constraint. So I left these circles here.

A

I left these four circles here, because you can snap to them once you're, actually making like XY axis systems or XYZ axis systems. I wanted to leave those. This is the axis. For example, you can attach the actual build platform to these halls. I left the vault belt, where the belt peg goes because, depending on what were the is attached, the motion will be reversed. You know if this belt is attached at the bottom. It will be one direction of motion this stepper motor driving this this carriage here.

A

If it's attached, if it's attached at the top, will be another direction, so that's actually important and then there's the what you call it the end stop holder so I'll go into that file. So I have a have this x-axis file I'm going to open up freak out here and just clicked on freecad. Let's have it open up? The idea is: I, went from this complex file just eliminated all the over fine details, the internal workings sprocket. You know belt everything just super super easy, but sufficient to allow you to model.

A

That's completely sufficient to now go fully forward to design a 3d printer of different sizes or use the same procedure as in this file. Simplification method to now work work with other designs like for will so will we're going to get started on CNC circles. So this is the final file you see here. I mean sweet and simple. All the critical details are here: minus the memory size. Ok, so you get a feeling for that. Now, there's a few details here that I've done that I wanna 1 actually make you aware of.

A

That would be a critical workflow for how we assemble this axis here. So what I did I'm going to go back to this document and it's actually fully detailed all the steps so I'm at here at I was here so what I did from this step? I took the two dimensional tool drawing and then I reverse engineered each part I'd simply redrew it from scratch actually went all into the sketch or workbench.

A

So so the idea was use dimensions to generate the part from scratch, using the part workbench whenever possible or sketcher, when necessary, I end up actually doing sketcher for all hours and thinking about that, and because the file ended up being 24k, I wasn't looking for any more memory reduction, but I could have, for example, generated all the you know. All the carriage pieces, just from cubes I, chose to do it via sketcher, okay.

A

So what you do there so take part by part going back to the index, we're identifying actually only six primitive parts. There's two rods here here, like the number is less here. What I'm doing here is like the motor has both the body of the motor and this plug. The motor piece has the main body of it plus those holes.

A

I identified those other features in the former diagram, so I know I have to include them so in this process here, I'm identifying, absolutely all the important parts, but then there might be multiple parts on one object file that you end up with later so I'm going through a very detailed process here. So.

A

And here in this example, and is drawing each simplified form, the part actually numbered them and I've actually put notes on how I generated them. This is just for documentation so that someone else wants to study this for a model of how you do the simplification. You can follow this logic here and see what I've done, okay, so next, what I did next was I saved each part as an individual file.

A

So here we end up with six primitive parts and I checked them off so I know each one is then I went through this whole process, so then I went into this table here. So this is all the individual parts and what you notice, like the ones are the darker green, are the ones for the carriage, so the chrome rods in this column, this row, the stepper motor, then the 3d printed pieces, the motor piece carriage piece idler and we're using actually long and short Tylar pieces, I saved them as individual files.

A

Okay, so let me give you an example, so so say the carriage printed piece when I click on that look at the file version history. Once again, here it used to be 500k I stripped. All the detail ended up with 6k a good deal. Now. Why was that 500k? Well, because it had that rid belt hole which has got so much detail. It's very, very detailed.

A

Fine structure ends up a lot of memory, but what you see, then, then you simplify, but once you see here in the file history, the point is: there's upload new version of this file, so I did not so for file management purposes. For making this simple I did not start a new file.

A

That was simply the simplify I, just uploaded new versions of the same file, while noting carefully what they are like, for example, simplified version, no sketch simplified version with this sketch and I'll get to that with sketch without sketch a little more later and I put any notes like if you can't figure out what to be low in all these files. I put notes here, so you can know exactly what these contain.

A

Now that this corrects the former thinking that, like what I did before like, if you look at the very table itself, you see there were there- was this red file link column where we would upload a new location for the simplified file? Well, no need for that to keep the accounting simple, upload everything over the complex files, because you have a complete file history and by clicking on when you click up here, it will get you download the most recent version. But if you click down here, you will be downloading any of these older files.

A

So if you, if I click on that, I will download this 12 of June 6 p.m. version and it's it says it's a simplified file without a sketch, etc. So that's the new paradigm for Product data management, ie our file management here that we're doing ok so next step. So let me go back where am I here file simplification here, so we've identified we set at this point. We have saved all the files. We're not done yet, though here says save file over the existing individual part files.

A

So that's the point, but the point is saved to new versions, one with the underlying sketch and one without to save on memory. So when you go into the version like, for example, in this thing here you go into this here. This is the final file. You see that none of these have sketches I, remove them simply by deleting them in the tree view, but here I'm talking about the individual parts remove their sketch one way to do it is by simply click the Delete key and the tree view or you can.

A

The other thing you can do is simply copy and paste into a new document. If you copy from one document into another to ask you if you want to keep the underlying information like the sketches- and you say no and it'll just copy the solid object without the underlying sketch, thereby saving 50% of the memory or some or some well actually, not 50. We see that's only 10 to 20 percent.

A

Ok, so now here's a pay attention to this now create a new document with a final Santa. So so what we've done so far was got the individual six individual parts now it's time to create the actual assembly. So we go add that we start from scratch. We.

A

And I'm going to show you that in the desc on my desktop here, I've got the individual files labeled one through six and I'm, going to show you how this works, so I took 1 through 6, so I'm going to start a new document. So this is a new document and then I go into file menu into merge. This is the critical part merging allows you to take another file and put it into this new file. So I'm going to merge on my desktop I'm going to select files one through six.

A

So this is a file one, four six. So what I'm doing here is I'm urged the so here's this stepper motor, the file I just saved so keep merging. That's the proper workflow, so merge project do file number two there. It is it's the motor piece in place.

A

It normally would not be in the correct place, but this is actually so. Let me just show you just to keep going so I'm going to import, not import once again, merge so part number three. What is that? That's that that's the other piece and then merge merge project and do I think five yeah, that's the Ross. What you're seeing here this is already like. There's been a lot of logic in here. This is already there aren't actually getting loaded in in the correct places, but they're, of course not at the beginning.

A

This is actually after I, assembled and re-save. So let's go back to the document to tell you what I did there so create new document with the final assembly, you merge all the individual files and they're going to be a mess, they're going to be just in a pile, and then you you actually assemble them. You move them and rotate them into the actual axis in the correct location. Do this for every part, and there were only six unique parts until the final assembly is complete, so there that was the final assembly.

A

This was the final assembly, that's what I created that that step and then, let's go to the next step of what we're doing here so step six update the individual part files with the correct position. So this is the trick, and this is an important point for workflow of redesign of complex machines. Imagine you have now something very complex. You want to just change one single part in order to to have that be a smooth, streamlined process. What you do here is you save the actual individual parts files after you've generated the overall assembly.

A

So if you take a look at this from here, what I did was take each part now and now they're in an assembled position, not jumbled up in in random places.

A

You save this say the motor, so you click into file, save as and you will save a version of that when you save it, it saves the actual, correct motor location. So it doesn't save it at like point at the origin like zero. It saves it in an actual three-dimensional location. So if you save all these parts, according to that procedure, then when you merge them into a project they're going to appear in the correct location.

A

So that's a very big point and that's what I'm making a point here, basically the concept of merging files, whether parts into assemblies or assemblies into a final assembly, that's the correct workflow for freecad for any module or any modular design system and, as I said, the point of that is to enable you to then go back, say that and modify this motor 3d printed piece.

A

Well, you go back to that original file and don't work in this document right here in this final carriage assembly, go to the original file to make the changes there and then simply merge after you're done, and it will replace the old one with the new one. So that is the proper workflow. So here I've told you how, when you save it, save the files from the final assembly, they will end up being saved in the correct location. Okay, step number: seven: remove assembly constraint to save 10% on memory. Well, that's I!

A

Don't know how much it memory! Actually saves, but that the concept here is say: I created this thing by doing various constraints using assembly to workbench like, for example, match the face of one cube like that, for example, here I move the motor onto this. This one by saying, take the bottom face of the motor and this top face and merge them together using the assembly to work bench, that's workflow! Well that appears as a constraint in your final preview. What I'm saying here is once you have the final file.

A

Those constraints are not critical that, if you want to, if you want to optimize for speed of manipulating these files, just get rid of the constraints, the motor will still stay there. But if you get rid of a constraint, you actually take up less memory. Now there may be some issues that we might look into why we might not want to get rid of the constraints in some cases, but in general, if you want to optimize for file size, get rid of everything here. All I have is actually individual blocks.

A

All editable, so I can select one at a time and I can do things like, for example, move them like I can move this say going to the you know: click hit one, you know, I can move that rotate or whatever I mean manipulate reasons you need like if you want to shift this carriage. All these are manipulable movable modifiable parts, because this is a merge of six unique different files. Okay, so next here we're saying that we're done so. This is an example of the x-axis.

A

So so, let's go through this here, just to the final overview and I'm actually going to back up for a second to say that what I said here is that we're saving like in this part, so we saved each part and then we said, take the yeah, it's kind of detailed. Maybe you can tune out to this. If you don't want to hear this detail, but but what we did in the step number six, which is update individual parts files with a correct position.

A

We did that onto the files that did not have the underlying sketches and you can do this two ways. One way to do it would be to save the individual part files in the correct location with sketches or save them in the correct location without sketches. Well, there's advantages and disadvantages to both. Of course, the advantage of with sketches is that you can modify the files.

A

The advantage of removing the working with the non sketch files is that you have slightly lower memory. So I was here optimizing for memory, but you could also as well save the files with the sketches, and so that's the end of the interlude here so now paying back attention. So here what you see in the saved files, when you see, for example, the individual part like the universal axis carriage side when I save this one here, I saved it as once again upload a new version of the file and I saved incorrect x-axis assembly location.

A

So in other words that file but placed as it would make up an x-axis. So in the correct location and I saved that when I save this, it was the one without the sketch and you can tell because the memory is the same as the one with without the sketch.

A

When you see this one, that's witness sketch, that's 13 K, so that's not the one. So you can kind of read by by observing all the files here what what this means. But here we mean that the version that I saved here it's the correct location, no sketches. That's the point of that. Okay.

A

So that's that's a lot of detail now going back to file simplification, so we end up with these very, very tiny files and the point of all this is now we can take this and, for example, well you're going to do the the CNC circuit mill, which is uses all the same parts, but the configuration is different. To give you an example: let's go back to the D 3 D, CNC circuit and they'll. Just didn't! Show you how you can make various modifications of various machines using the design system.

A

So here we have a conceptual design. This is what it will. Look like so so from from this. You've got the universal axis and here I'm actually showing 1-inch axes, but we can do this with the 8 millimeter, but so you've got one y axis, 2 X axis another Y axis. The Z is actually writing on the carriage it's not independent, like in the 3d printer. It sits on a side here. The Z is writing on the carriage, so a little difference. So the critical things.

A

For example, when you make a CNC circuit mill instead of the printhead, you have a spindle, you have a motor, that's hung here and their requirements are. It has to be the right space. You have to make this mounting motor piece that will mount to these. These other pieces are the spacing between these two pieces has to be the correct, spacing to fit the motor in there.

A

So, instead of this carriage piece, we might, for example, use two carriage pieces, so that spacing is exactly right and in this system we can do a stepper motor on each y-axis, a stepper motor on each x axis and a stepper motor on each z-axis, so 2 Z, 2, X, 2 y, so six stepper motors altogether. But you see here how you can modify, make various modifications and then to go even further.

A

If we go to the 1 inch Universal axis, there's a like, for example, we want to make the CNC torch table, so this is actually the the motor mounting piece for which fits one inch 1 inch rods. So this is much larger. In reality, this is back from 2016 from last year as few different details. Details here are that you can do NEMA 17 motors. You can also mount NEMA 23 motors in the larger holes, so we're actually made it very modular and I think you can also mount NEMA 34 in the same one.

A

So it's a multi-purpose Universal kind of access thing, but the idea here isn't if you've designed the CNC torch table.

A

Now you take these larger pieces and fit in the pieces that are required to make a torch table, so the bottom line is, we can make a lot of different variations and we can distribute those tasks to different people, including, like aya, was starting to work on one with with not the metal frame, but just say with PVC tubing frame that you can actually glue the axis elements to that using crazy glue and things like that for a very low-cost version. That kind of summarizes the what's happening with the file simplification and then from here.

A

What I have done here like here with all those greens? All these files have been simplified, the main axis files.

A

If we do and then that's enough to do basic design, we can we can hold on to that as the basic starting point. Just those six parts are enough to make the axis now you need to frame also in the frame like, for example, the frame is shown here.

A

You'd also need the frame obviously to work with, and then you can just design all kinds of configurations of this, and the idea is this is like well. Why do you need to do that? I mean you kind of know how the axis looks.

A

Why not just build the thing, but let me assure you that if you do that with a physical build, it takes significantly longer to do the physical, build sitting by trial and error than to figure out all the details and CAD and then build it and and I mean that's obvious in some way. But it's also not obvious, because most people end up never really doing the full gory details and CAD, and then they spend a lot of time doing the actual physical build. But that's not how we do things we do here.

A

What we do is design it perfectly so that when you actually build it, it's quick, then we can create all the instructions and everything else so with that said, I think I want to open up to questions here on what what this process looks like. But we are here ready to pretty much start designing. Other configurations like what I'd like to do is: we've got the CNC torch table and the CNC circuit laws, the machines being added to the pool.

A

As far as continuing with the 3d printers, we have a lot of different frames left over from last time, with 13 and 10 inch frame sizes which are from the nested cutout pieces. Those need to be designed for you and then the figure of Merit at the end is you look at the nozzle location and you can look at okay now I get as such in such print area. So we want to verify within CAD that the print area is adequate.

A

I mean the main thing that you figure out by doing the complete design is once you mount the extruder on the carriage here, so the extruder has has to be another another one of the files that we actually absolutely need here, like the extruder file, which is uh where is that here.

A

Extruder, whereas my extruder.

A

Wherever this extruder assembly is number 28, we have to make sure right. That's not in this this spreadsheet. That needs to be a. We need to emphasize that. That's one, that we absolutely need for the design of the 3d printer, because without that you can't tell what the actual print area that you're getting or if there are conflicts. The main thing to look out for is you've got your extruder on the carriage. What exactly is the allowed geometry? How much motion do you get with all the constraints given a frame?

A

And you know the whole motion system? So that's the main thing to figure out. That's you can say essentially that's what we're trying to figure out, because you can build it.

A

Yeah, it looks great, it looks, you know, looks like it works, but you end up with like a couple of inches of motion range, because you didn't pay attention to how you align all the axes and so forth, because the different variations we can do like for the mini, for example, we're mounting the axes on the outside of the frame and doing a little bit different mount systems. But anyway, we can basically start designing to make sure that we have the required print volume at the end of the day.

A

So with that said, any questions on this process, because this is very important. This is like the critical workflow idea of saving drastically reduced file sizes by looking at the dimension drawings, to pull off all the dimensions and then redrawing the things in a very, very simple way, and it doesn't take a long time to do a dimension drawings. That's pretty quick, and then you simply reverse engineer. You start making the part from scratch, but just much simplified any thoughts here on anyone.

A

Because if not, we can go into role, allocation, I means I'm, sure you guys have questions you kind of have to study this file simplification document and go through the process yourself to get a handle on what that all entails. But yeah I think that's a that's a good workflow, relying on merging a files into one document, which is the critical workflow where you have all the individual files. And then you merge them into a build document.

A

Questions anybody you can, please feel free to speak up otherwise I'm going to go back to the working doc and talk about the role allocation for the people that are here and see what what we want to do. But the idea the idea is, we need to get a 3d printer, build workshop on a schedule so kind of waiting on.

A

We want to have the new website up. I need to pretty much shake down the 3d printers here completely to get like six of them built, so we can print parts rapidly and then the goal on the torch table is that August 25th. We have a build of the brick press and power cube. We want to be using our own torch table as far as the CNC circuit mill.

A

We got to do what we can. Actually we've. We've got a guy come in here next week, so basically we have this week and next week we have a guy coming here for two weeks where we're going to build the actuals using the all the different components we have all ready for the 3d printer. Just do that. Cnc circuit mill version I already have ordered the spindle and all the parts. So we can mill circuit boards, such as controllers for the CNC torch table or I mean even Arduino.

A

Is you can mill those out the torch, high control or anything that we do get cnc milling capacity up and running? So what you see here is that we're kind of maxing out this universal construction system to build all kinds of production machines that are critical and but most important is the NC Torx table, because that's how we cut all the different stuff out, all the metal for the heavier machines, yeah.

A

Yeah can the dimension stage happen only wanting to be the original, complete file, yeah sure, I, think a question from I. Oh yeah I mean with the original complex file what we should have there and that's what I did I mean in the file.

A

Let's comment on that and comment on data management for that, so in this file here this was actually from the complete a full file when we, so you have a working file for this access assembly, what you should do, what the good work flow would be is once we have the dimension, drawing added to that, save that as another version and uploaded over this file. Noting in the comments saying hey, this file has the dimension drawings because I believe when it, when you save the dimension drawings, it actually saves also the underlying 3d CAD.

A

So you can then edit that or modify this dimension drawing things. So we can, you know, make it better like take out unnecessary dimensions, add dimensions that are missing, but yes, this step here needs to be done once here. I generated it here because we didn't have these yet so actually this points to a workflow where we should generate all the dimension, drawing dimension drawings as one of the earlier steps, so that at this step, when we're simplifying the files, we have all that to look on, and you know we have it.

A

We look at this on our screen. At best, you would have two screens one. You look at the dimensions in one screen and then the other screen. You have your freakout screen, where you're actually drawing it up, it'll be a good workflow there.

A

So, let's see what else, and then we'll I was wondering how to simplify files. Rotate relate to the original, more detailed files. Will those still be used? Yeah I mean the point: is you use what you need that meets the best purpose like if you're actually doing a like generating, for example, the 3d printing files? Well, obviously, you have to use the full detailed carriage piece with all the belt teeth say, for example, it's the carriage all those belt notches in there and so forth. You use the full file to generate fabrication, drawings, renderings.

A

Definitely the CNC or cam computer-aided manufacturing files, whether it's it's, the 3d print files or CNC torch table files or whatever, that is that comes from the full file and then, when you're doing a new, completely new design, then what you want to do is you okay say you want to modify the 3d printer from as an example 16 inches to 8 inches? Well, you use the very small undetailed files.

A

Why? Because you can work with them fast and you can get all the required geometry, but if you want to say print the 3d parts? Well, you know that those parts are the same as the the first full detailed model. So you just printed off the original files, while it's basically depending on what purpose you have in mind, you use the correct detail file for that purpose.

A

Yeah, the the relationship between the full detailed file and the simplified file is that the critical dimensions like the outer dimensions are identical. For example, let's take a look at you know. Like say this say we take okay. This is idler piece here. The original file has 55 by 66 millimetres, 24 millimeters high. Well, the final file is a block like that exact same dimensions, the bolt holes because we know they're there we all we know is you know just to give you an example.

A

We know the bolts are there to bind the two clam shells together. We know the magnet holes are there because we can attach this to a magnetic to to the metal frame. We know that on the end, it actually has these nut catchers. Like you see in a motor piece, those two small holes, number 13, they're nut catchers. Basically, you screw a bolt in there there's a nut in there and you screw that in it. That piece has to be in there.

A

So, basically, the relationship is absolute, identical dimensions and critical details that you need to work with, and so for example, here that all the character pieces are identical, identical dimensions for the motor I didn't necessarily care that they're exactly is basically free, handed the shape of the motor, because I just wanted a small file and then I put the like a square for the the motor connector and that's because the motor does not touch anything. Therefore, its dimensions are not critical.

A

I mean it can be a couple of millimeters off without hurting anything, whereas for these 3d printed pieces like the bolt like I cut the bolt locations here, those have to be identical. Otherwise, if you know they're 30 millimeters in this case right here, if they weren't you couldn't attach, for example, at a right angle, say the idler piece to that. If you want to attach another axis, so certain things have to be absolutely critically identical and accurate other features don't, and you kind of have the general ideas.

A

If the thing is touching something, it has to be exact dimensions, so, whereas the the stepper motor did not have to be exact dimensions for the these pieces, which touch other pieces in general, you have to have exact dimensions like the hole for the rod has to be well we're actually not even including holes for the rod we just avoid.

A

We just put the rod into the solid yeah, but you have to just basically think about it and the idea is it's like a like virtual reality or like representation, it's an action and that's the simple files and abstraction retaining the critical details. Yeah.

A

Okay. So let's let with all the people here in time left here, let's go to the team roles here so on a dev team here. So let's take a look at with. If everybody is accounted for here, so we've got Joseph I know: Joseph is working on instructionals.

A

So that's good work happening there. You develop an orientation.

A

Abraham kind of had to go because he didn't have the time at this time to commit to the team Chaz. How are you, how are you well actually Chaz, is on the CNC tour table, so we don't. We won't cover it now, because that's the next meeting and extruder so we'll leave that for now as far as myself, I'm working on the print cluster here, so that's my update on where I am.

A

Roberto we've got silver. Bert is working on a very important part, which is how do you do language, agnostic instructionals? How do you extract these nice isometric views, for example, for the 3d printer? How do you create an instructional based on that, so all of us will be doing since he was more ahead. We had him actually document the process that he used.

A

If you want to look at his log, you can see some of the base of the look at his log to see the nice work he's doing on that language, agnostic instructions and I think we're continuing on that. So Roberto, please follow up with me on if you're stuck on any of that, if you need to go forward on that, I think you're moving along on that now assembly simplification, so here cédric IO Israel.

A

Can we allocate you to some tasks on that because, for example, so, okay and we'll so we'll I'm allocating we're allocating will to the circuit mill version and will the owner pipe in here? Do you kind of now get enough to get started on CNC circuit mill, based on what what's documented.

A

I guess simplifying the axis, so so we have the x-axis and what I? What I can tell you right now, because the y&z I mean they are different in ways that are at this point, if you're not making the actual super correct, if you're doing just the geometrical fit and first cut design, it's sufficient to use the x axis for the y and z y, because they're outside of some details of how little orientations of things they're identical. So we have all the axes you can actually at this point start working on so just add.

A

The frame which are, if you look at the frame page from the index of parts you can get. The frame frame is basically flat sheets of metal, but you can do that. The only thing that's missing is the extruder, so the extruder needs to be simplified and it takes like a half an hour to an hour, maybe 2 hours, depending how fast you are to draw up the critical dimensions. But what you do is once again take all the critical dimensions out of drawing dimensioning and redraw those critical dimensions.

A

The main thing you're looking for an extruder is the exact location of the nozzle, because that determines where the thing is printing so, but we should go through that whole process of well, but you're, not use or you're, not using the extruder you're, just using the the spindle motor, which you can draw that as a simple cylinder. So in that case it's actually simple. If you actually do the extruder extruder, has you kind of have to study the extruder a little bit more to see which dimensions are critical and which aren't?

A

Because there are potential interference, points there? But that's not within your scope, so what I would say? Do there I mean I would say, because we actually need this 3 visa? The circuit mill geometry, like ASAP I'll, work on that a little bit and we can coordinate on that because that's something we pretty much got a crank out for next week.

A

We have one to two weeks to do that for actually two weeks this week and next week to work on it, but we have to have a rough design which we can do I mean only. It would take a few hours to come up with a rough design and then we can start looking at the details, just evaluating it to make sure we've got like, say a 5 by 5 inch working area, so the first cut of how do you?

A

Actually, you know which frameworks like will at 13 by 13 inch frame, get you the necessary spacing. Can we use a 10 inch by 10 inch frame or whatever? So, let's, let's explore that.

A

Let's see I see, there's a couple more questions here from.

A

So here's that Joseph is piping up so before we leave Joseph is worried and just so just remind me, we are making an introduction. Welcome video to all the new developers and Joseph is working on. What we wanted to do is do a everyone turn on your camera. Stop the presentation and say in a wave: don't have a delivery, but whoever has a has a camera.

A

Do that wave and say so select see I'm going to stop mine so Joseph. What do we say?

A

Welcome new developers everybody's got to unmute their thing. It's probably going to go out of control, but let's try it and who's recording it are you recording it.

A

Joseph the other way to record the screen, because I'm recording Ballmer I'm only recording on I.

A

Think Joseph is working. What I can do is I can actually set up a okay. So what I'm going to do is I'm going to actually quit this recording I'm going to capture the whole screen here. Wave wave welcome to the team, whoever it has a video camera wave.

A

Anyone else, okay,.

A

Big smiles, all right Joseph, is that good enough will that do okay, we'll take it I'll? Take it all right, okay! So let's continue just a little more just to wrap up this so I, oh, um given some of it so you're definitely learning on afreeca great work. There can you take on I mean: where can we take it from there bio.

A

Because I'm thinking like the let me just just pipe in there, the idea of doing the simple if you're talking I, can't hear you, though, if you are but um the simple, simplified 3d printer with a basically PVC corners like the XYZ PVC corners, just PVC pipe like a super low cost accessible thing. Does that still on a table? Can we do that?

A

Yeah I can't hear you, though, if something is not working on a on a voice.

A

A

A

Okay, yeah work on that. As far as that, all we need is a very simple frame system out of the PVCs and I know you I mean one way to do. It is I mean there could be different versions happening there, but we do know that, for example, like Menards in America, you've got these X Y Z corners. So just maybe pull that off the internet. And for your case, if you don't have that Menards in nigeria, you can. We can assume okay, we're going to 3d print those corners for you or something like that.

A

But if you can do it off a standard commercial off-the-shelf part, because that means that some people can buy it off the shelf and others that have a 3d printer can actually print that out themselves.

A

So that'll be the good case in point of what to do and then once you select the frame size, you can pretty much make the lengths any length so that you get say a 12 by 12 inch or an 8x8 print area which are standard print dimensions, so they're for you to optimize your size, to of the frame to be exactly that, therefore, the figuring out is: what's the geometry, what exactly are the frame members sizes to make it easy, but I would say one thing: don't make the XYZ different dimensions.

A

I would say, try to make the all the lengths of the of the cubic frame the same dimension, because that means it's just much easier. You know to cut it out. You just have to worry about one length as opposed to three lengths and then Counting. Okay, do I have four of this line. Four of that land. 4 of that life? Is it's one length it's just much easier to build so little things like that would be good, so design a version with same XYZ and then once you're done designing figure out exactly.

A

If you have make sure it's got the eight by eight or twelve by twelve print area that you can access with the tip of the nozzle. So that would mean that you would need the simplified version of the extruder in order for you to be able to manipulate it very rapidly work with the rapidly yeah.

A

That sounds good. So, let's see if we can get you going on and just I want to back up to one question: what's the difference like regarding the simplification discussion? What's the difference between the merge and the import function.

A

Of the assembly workbench, so merge means I, don't think, there's much difference. Merge works with freaking files, whereas import means you're working, you're importing something like, for example, step but I think overall they do pretty much the same thing. The merge is unique to just freecad files. I, don't think merge allows you to do anything else, but free cat files, so quite similar. Just a file format is the difference and there is a difference. The point to to keep in mind is why don't you just open up the file instead of merging it right?

A

Well, if you import sorry import, meaning just open up a file, if you open up a file, you actually run into a risk. If you save something over that file, you have messed up your file, whereas merge it does not touch it does not. You cannot edit. It just opens up a new file, so we cannot mess up the original file. That's just only distinction there, so that sounds good. Okay, so we're getting on into the second part of the meeting here then, on the torch table.

A

Let's see do we cover just about everything, um yeah I think so pretty much other people are a wall, so we go to the extruder and CNC torch table. Okay, so we should probably start with Oliver with the main update on the CNC torch and then move on to the extruder Oliver. We want to take it away and other people you're welcome. If you want to stay, you can. But if you want to leave that leave the meeting this, this is just on a torch table and extruder the filament extruder. Yes, we can hear you.

B

Okay, that's pretty good yeah! Okay, so ask me: take happened on Thursday, so it's not long ago what you.

C

B

B

That I I made I made two for our pages and so less injury forum, which I marked as being for English speaking and I, made two of them, one for free cats, user group and one for kicad of the group and the ideas. Anyone has questions related to freaking, Aki cat, or we want to exchange tips and tricks or difficult cases. You can have there a discussion and advantage of having it in a form this that it is conserved for the future, meaning of our people can also profit from it.

B

On my time we can do things like an SR cubed, which we pin on the top and the normal form stuff I like to work this morals. If you go there, I cannot promise that each question will be answered, but if not, then there are many more people who can keep track on this problem or whatever yeah. That's one thing what I did and yeah the other thing is: I made some the last ones: fine tuning stuff of the height controller, PCB, meaning things like I, ignore a checked for the screw terminal things.

B

We talked about last time where I said I had this molex connector from TV supplies ah splat, and it is simply possible to exchange this with screw terminal or you can, with this angled one screw terminals got the heads the same footprint accent.

D

B

And okay, so no no change in at this point and then I exported the Java files and get files and set up a project that Islip that's the okay take much fun.

B

Maybe you have to I'm, not sure. Maybe you have to be an ice made. A screen show, however, how it normally looks them now and yeah it is. There are isolated system that is similar to both age park, which is made in more familiar to you. Yeah.

D

B

Can upload open source circuits and CDs and everybody who wants can come or order them yeah.

D

B

That page 36 euros and therefore I get three pieces and that's what we want to have and scow I hope they will be delivered, who they say they have a production time of about Wednesday's lead here comes comes earlier. That would be welcome, of course, but yeah. This is when, when I asked, when I expect to get the other thing is related to what we talked in the email about the manual version right, yeah.

E

B

Here I ordered today the rotary encoder, that's called KY. The bureau for 0hs is drilling.

B

B

Like this, but it's the thing what what I showed you did, the similar thing, what what we have seen and the adafruit drop-bys a little bit cheaper and I ordered a few of them and I hope to get them in three days three or four days, and if I have them.

B

I can start immediately with what you suggested in the email yeah, because that's quite you one could even do it on our honor on a breadboard, and you asked well that makes sense to develop that in parallel and I would say yes and TV and I keep you up to date of all the steps I'm doing and then you and try to implement it at your side. If you want here.

A

B

We shouldn't be quite difficult. The next.

A

B

I am, fortunately, I have ordered a ramp few days ago, rats with something what I normally like, Twitter to or I'm used to heaven stock for cases like this. So we can work on this doing on this yeah.

A

So yeah, so let me ask you so if we do the manual controller, do we simply use Marlin or do we use some other firmware yeah.

B

That's the thing I talked to times ago and said: can utilize an older version of Marlins and Sprinter, because that makes nice code and I have been looking for my old versions for something with that and I will just make American teachers first phone call and rely.

F

On in spirit, absolutely.

B

Regularly learning in.

F

The non-english the confession digital marketing firm, what only everybody how much on or heaven yet someone working for ownership is now available normal kindly if it's the light at the shoe shop so on as all at mushrooms, all right. Well, water, mushrooms,.

A

And C&C torch tables, sprinter I am.

B

Sorry exactly you.

A

B

Yeah I'm going to keep taking deep a look in it and I'm, not sure, maybe I'm programming something new from scratch. Maybe I I Taylor, this sprinter version I, would see what once what works better or yeah yeah man I what I'm talking is for the further from the right controller. You.

D

B

Also is, in the background is like be thinking of utilizing, rams or universal controller boards for all kinds of CNC machine. What also is in the background, and maybe know to use grbl. That could also be an interesting thing, but this is also a little bit bigger I mean from simple hype: controller task. Maybe I can program it from scratch and then another thing you ask whether I have some some knowledge or something concerning the rotary encoder, and so the things doesn't seem to be so complicated, but I found them very nicely.

B

I just dropped it to you seconds, I've prepared it already. I appear this and there you can see. Probably.

B

It's not too complicated or I'm, confident that we can get it working and yeah and three or four days when I get those things delivered, then we will know, probably more so that is very.

A

B

A

Nice and I also see on that you print 3d printed, the linear bearings, oh.

B

Yeah that was related to another project. What I'm doing I want to add a new slider element for my universal proto prototyping kit, which I had before an older version. Where I did this with PTFE and little is not so good because the screws are with three millimeters. Diameter are too thin and the PTFE, which has a lowest friction, coefficient it's interesting material, but it's too soft. And so you have not such a good ability.

B

And then I came across German company eiger's, which is doing all kinds of the bushings and in ER drive things, and mainly because they are working with some special kind of plastic materials and exploring this, and that's have brain expertise on room.

A

B

Near bay, they have I think one year or two years ago offers 3d print materials. They have three different material.

D

B

Stock and I choose the cheapest one. Four four give it a try, and this is what they call tribal filament I. Think tribal logic is a science of friction or something yes,.

A

B

This I want to use for designing my slider element and, if I headed here I just printed a version of this lm8, you like or shaped bushings and just forgive it a try and so far what my camera would work. I could show you the XS with that and well.

D

B

Also, what I've noticed in the a mate a met, a 8c meaning in it? It is a very local street, 3d, printer and I've briefly.

B

Do it one for air for building also, my little print class, like you and the Kuna scene, community theme of this or around this. There is a absolutely fashion at the moment to break up the the the sliders and the carriage and pull out the metal, linear, bearings and replace them with some plastic bushes from from the idols company. So they hope to achieve that. You have less less water, less play.

D

B

Bearings and second be less noise, no uh noise level, yeah.

A

Let me just ask you: how much was a roll of net moment.

B

20 euros for 250 grams roll, and that was a cheaper one. They have also for 40 euros another, but this has special attributes which we do not need. So I think that she one will do at least for me for testing at the first moment, and the interesting attribute of those materials that it is about, 50 or 40 times has less, is less positive, using particulates by by grinding meaning tendon abs, meaning abs of 50 times more upright than this material. How.

A

B

A

Would it would how well does ABS work for this? Sorry, for this purpose would ABS work at all I printed I printed, some from ABS and they were a little loose. Maybe, but would it work, would they last or oh.

B

Yeah, probably but it's tribal stuff, we do it. The name sounds like blocking of Moria bus. However, if this lasts 50 years, then the ABS thing will probably last only one year. Here's my lasting I mean it's sliding. It says what what says working.

A

B

A

B

It's part of the plan that which uses a particle go by the sliding and grinding away, and but it should not be too much find or the problem is as soon as you get too much grinding, then you, you will lose precision because the theorem gets more wobbly. You.

C

B

Who have a hard material guitar like that yeah.

C

Miss marina, actually.

B

Bought it because I was curious and I I anyway wanted to rework my mind, slider thing so far nice, you know, and since it has in this case exactly exactly same dimensions into the dual axis carriage, everyone can choose my one. You want that I have a metal one in your bearing or this princess bushing. So it's again typical and situation of the FCX and yeah.

B

That's so far, I'm pretty happy and by the way, I tested how how it's going to printing it's similar like ABS little bit different, but you need a little bit higher temperature in the hot hand, but on the other side games, not really hot temperature on the heat bed, or can you print it with the cold heat that and it prints quite accurately and doesn't smell that and whatever sold in one word? It looks promising for me how.

A

Come so does Teflon work.

B

Yeah Teflon is a pretty heavy stuff. I talked from at the beginning, I think with an today modern all-metal hotend should also be problem. I'm, not I'm, not really sure. Normally, the melting point of Teflon is about three 320 degrees centigrade and if you can reach this with your hands- and you can try to prove this, but otherwise at this point, the Teflon tokyo starts emitting very, very poisonous things. That's why my tan, meanwhile, is from cast iron in from from smoothing iron, and I don't want to have this pencil.

E

B

Sheet there is a button from from my other project, as made also the experience that Teflon is a little bit too soft, yeah I tested it with Teflon I tested with del rim or pol, which was it a bit better and I, and by the way you asked about ABS. Of course, I know lots of designs on Thingiverse with which are made from ABS I think from the hardens and elasticity.

B

85 was abs, but it's more private here.

A

So, okay yeah! Well! Thank you! That's good excellent updates. So we'll wait for you on some more comments on the simple manual controller yeah. So the good point is with a yeah we're trying to get the give the automatic bed level with capacitive sensor for August 25th. That's our production run of the brick press, I'm committed to using our own torch table on that.

A

But if we do the manual version, we can definitely do some cutting, so we can make that a standard practice because it's doable, you just have to watch it by hand and that when we're cutting a lot of half-inch steel, it moves pretty slowly. So you can easily follow the the course getting a setting resetting the height if you need to as the as the work goes along. So that would be great. That's that's really good!

A

Finally doing it finally want to do it in-house a lot of times before we simply outsource the steel cutting to fab shop. We got to start doing that. I mean we've done it before a long time ago, 2012, but after that we never got it going again so yeah. This is great look forward to it. Yeah.

B

I was thinking your suggestion to do the manual graphing there's a very clever strategical chess move regarding your timeline and the deadline for the workshop yeah.

D

B

Thank you. We are definitely more on the safe side and you.

D

B

I'm very confident on them and on the other end the PCB or the other PC giver. Maybe we are lucky and get the fast running. I mean reaction is not away with it, but we are more flexible with what the timeline. Yes.

A

B

Oh, what a dress, yeah.

A

And if anyone's watching this video recording and knows about capacitive height sensors, we're doing the open-source capacitive sensor join us email me. If you have experience in capacitive sensing, because we need to figure out the electronics here. Alright, we've got the board, but the shakedown is going to be we'll see how it works in practice and now I'm going to reach out to Paul Neil ins, who design a circuit in the first place, to see if he can help us out. Yeah.

B

A

B

You wait a few days. Try a the thing, because.

D

B

If you ask someone for I, think debugging you, if you can describe your setup, what you ask them and then can watch it and by the way, there's a chance that the thing will run from this graduate yeah.

A

B

Optimistic on that yeah.

A

B

Must not ask for immediately yeah.

E

B

Let's ask him: if we have a concrete set up, then we can tell how far we came and where the error occurs or whatever excellent.

A

Yeah yeah great suggestion. Thank you. Keep going! That's really good work: okay, yeah, yeah, okay, Chaz buna, pipe in Oh.

D

Thursday's mean I've been working Thursday through Monday and I.

A

D

A

Bit: okay, so I haven't.

D

Gotten anywhere really um I stepped or the wires for the power supply and.

A

D

I, just look at the universal controller Wow for the first month and something against obably we got next is start generate. We get files for the board's.

A

D

Was Bobby will have next freakin.

A

Files for the actual, like how the whole controller looks like, like all the components together, yeah.

D

That's what I thought you were gone next yeah.

A

They'll be pretty good and how about like? How far you long on just a circuit diagram. So we have something: that's a good reference, that's distilled to our particular I. Only.

D

Have what's posted on my log? Come.

A

D

Work on that yeah, okay, this Thursday's mean I've been working. There's aq Monday understand interview today, yeah.

A

Yeah I think a good step for that. So so, if you look at just just to put it within a framework of the CNC torch table, so I'm sharing on a screen the current critical path. But the idea is that on a tool, the date down here, that's August 25th we're here like June, 12 or 13, so we're at the Green Line August 25th is the CB press power cube, build and then, after that, we're going to do another prototype of the tractor in September.

A

So part cutting is slated for that's like July 24, so we want to with Oliver's work the height controller, so so mechanical design is coming up like in the next week, like we'll have to get into that pretty soon. um There's mechanical design on the CNC torch table, but then the build would be about July 17 according to the current plan, and before that we would want to probably shake down the manual high controller like July 10, but the idea there is, if we do, the mechanical system build.

A

That would require the larger stepper driver to drive more of the stepper motors in that case. So mostly.

D

The CNC torching all that yeah.

A

Yep, so that's there. Thank.

C

A

Also, there's a the page on the wiki called critical path. That also gets you to the CNC torch table, but the idea there being so the electronics design here is ongoing. So we're designing and shaking it down, it's Oliver's work.

A

The mechanical design is refers to the one-inch axes that I talked about in the previous meeting here or an hour ago, or so regarding the much larger rod size, but as far as the electronics that follows right after that, so so the critical things there are wiring diagrams and it would actually be more important if you could possibly just join right on the mechanical design of the lure of the CNC torch table with a one-inch axis, starting with the file simplification that will allow us just like what I talked about today, simplifying those files so that we have the rapid, modeling small part files for the entire torch table.

A

That will be useful as well. Is that something you'd be interested in doing.

D

Yeah, hopefully, I continue. It's like electronics, yeah.

E

D

I'm fine young.

E

D

It's something like I, also work on videos right now, just an issue with time, because yep um I'm looking for another job the weekend, yeah.

A

D

A

D

If you want me to I can do mechanical design that is open to like no.

A

D

Maximum or yeah.

A

Yeah, no, the wiring is important to make sure. Let's, let's continue on that, make sure we have the wiring diagrams. If you want to draw the actual, you want to do the freak out of all the board layout, um just basically like all the physical arrangements of the entire thing right. That's what you're talking about yeah yeah yeah! That would be important too, because that'll be part of the the whole overall mechanical design. There too, so ya know be good. I mean it's. That in itself will take a lot of time.

A

So yeah continue with that they'll be good mm-hmm, all right, yep all right! Thank you so so that it covers the CNC torch table. So let's move right into the any updates on the filament extruder with aid vixen and Cassie who's going to review this later. So the idea is: we've got like Nixon. You said here you're doing some of the looking at the different files. My my impression on this whole project is that we want to get into the CAD as soon as possible, without waiting for for mr. lineman to provide their CAD files.

A

So we could possibly start looking into just manipulating those I think with the with STL files. It should be pretty straightforward to start assembling the different pieces together so that we see how the parts fit. Is that that so, would that be a good next logical step? So maybe one arm you want to pipe in your Dixon Dixon, okay, Abe.

E

Our work of holding freak at some extent there I guess you want nothing and Berkman. Let me just want to measure a little bit. I, don't know by 10 certain tools and forgetting little bit a little bit before trying to convert the STL things like the attics modified in a little bit, probably kind of pieced together, cuz, sometimes I do need. It helps to get measurements on things. Yes, injuring evidence like that, so not having happen to questions, but that is kind of probably holding a stuff on details.

E

We need to know exactly how certain stuff fit together, because there's some places where it's unclear what cards are exactly how they're going together just from looking at the PDF documents, the alignment had already so right.

A

Are we hoping that we would get some input from mr. Lyman or we just got to figure it out ourselves? That's.

E

The last thing I remember, the email Wednesday was looking through and trying to organize his files better and I think some of the part library documents from the zip files. Already we had some problems with different parts or persons of parts that were in the files together. It was.

D

Obvious? Which.

E

Ones or why they were out the way they were, there's no redundancy there. It wasn't perfectly organized the way it and it's what he said last was that he was going to go through, try to organize and provide a complete or complete set of CAD exports or something for us. I haven't heard from a little while I said: let's take him some time.

A

E

We could probably attempt some other stuff to get moving on stuff, but would then kind of float to putting the spreadsheets and fossils them together. I've been today even copying, links into the spreadsheets and so offers a index so moving board with that it just takes a little time to copy, laying and all that stuff into the spreadsheet.

E

So far, but I think I've got a pretty good layout on the master index running it not have too much redundancy with the ball, but can I have that song so more details to work on a bunch of those related documents, material things like that even closer to the way.

E

Some of the other documents and templates are yeah progress on those. So.

A

Yeah um right because we get, we really got the cab. I think the logic here is once we get all the CAD files together, like we see how everything fits together and just makes it much easier to build, as opposed to trying to figure things out off and complete documentation. Is that kind of how we're thinking about it?

A

E

Cat yeah or just cat earlier that was kind of somewhat of a priority to help us figure out how, as to assemble the Machine, exactly.

D

E

Even want to get somebody's wouldn't want to build a W yeah.

A

E

Extruder is kind of the killer app for the Ephesian predator, really so yeah be great to get closer to actually building a prototype. I yeah.

A

But my concern is, like I mean we're kind of like at the complete mercy of when he gets this done, so it doesn't really it's like. What do we go about that.

E

Yeah I think we just start tracing certain parts or try to do a simple nasty. L sounds like an interesting method to check some of that right, because this forget, let us put it together and make a little. Let's.

A

See if we have like, for example, can you move SPLs around like, for example, in the draft workbench? If we could assemble things, can it can we do that or uh I.

E

Had steel files in there and I thought, let me let me do a variety modification. They act like a independent part.

E

They can be strained. Let's.

A

See saw I'm looking at this right here on my screen and see. Am I sharing my screen yeah? So, for example, that's an SPL. If you look at that, you know, can we actually, for example, rotate it? Can we take a point.

A

Yeah, it looks like you can you can, so you can manipulate them, you can move them around.

A

Maybe we should just take them and I mean that the hard part is going to be just getting the dimensions, because if you go into the dimensioning workbench I just tried this right here. Drawing dimensioning.

A

If you set up a new page, you try to click on it and you tell it to put in a apart. It doesn't recognize you selecting the heart, so you can't put it in into the dimensioning so we'd have to. We have to find a workaround for how we actually give the parts in the dimensioning, but we can just trace over like like, and that's the only thing we could do.

A

We can just simply trace over things, but let me see that's kind of tricky because without like the nice thing about the drawing dimensioning, is it snaps to all the corners? So you get the exact exact dimensions? It's so easy! You do it so rapidly, whereas with the like, with the measure distance tool, which is how I assumed we would be measuring things by tracing over I mean you just lose some accuracy. So so we can get pretty decently accurate things, but they weren't wouldn't be super accurate. But maybe that's not so critical here.

A

Maybe we should just just trace it over and just start it. What.

E

Questions, do we have I guess American I know that there are the Assembly of the equipment. Are pretty rough really right.

A

E

A

E

Thing, though, yeah.

A

Yeah, can we maybe never yeah? Can we can we start on that done? Okay, yeah yeah I mean yeah, I mean the CAD. The cat overall CAD file is like the glue of everything so.

A

Let's do it, let's do it, I mean, let's just let's see how far you on like organizing things in spreadsheets visual bill of materials, yeah.

E

Let's see the build materials has been good for a while, but let's see the master index has been, it can be a lot longer and I probably haven't got higher than that. But it's copying painting everything a little time in there was interesting way to input. All the data at once must have crowd of change it more than the way Lyman has it in his PDS to try to get closer to woman I know we want similar to other spreadsheets with more information. Mm-Hmm.

D

E

Kind of remember for the matter index I kinda I was trying to flustering something extra heard, you're seeing links it's almost so on, like that. I know, there's plenty of room for that in the Bill of Materials. We probably need lots of space for links and things, but I figured in the master index minimizing some of the make sure specs wasn't important repented things, but it's mainly just the links item, specifications in developing CAD links and then we can add video links and so on later that's I. Don't want to do with the spreadsheet yeah.

A

So this is an extra spreadsheet and Kathy did this one here, which is partially done, as in like the links to the very like, for example, yeah those links, we really need very specific links like, for example, this is just linking to web sites as opposed to the specific part files. We should do that as much as possible. Maybe we could have Kathy Snyder I, think.

E

That looks like the copy family from his PDF brush.

A

E

My experience when I was doing that I was trying to cover the whole media and it wasn't easy shut up with a copy little pieces at a time of these spreadsheets with paintings along right that the links from his stuff are okay, that he has mixed part numbers.

E

So I tried to adjust it more like some of the other example template spread jeans yep from the index and I know, there's that d3 materials 16-inch spreadsheet, that has a really good layout. There's a good example to build materials. Yeah yeah.

A

Yeah, what you got here- that's that's! Pretty tight, nice and tight I. Think the one.

E

What I'm thinking for the fill material is.

E

A

E

Lot of space for links and supplier information and very cool so on right.

A

Like this one that I'm showing the part spreadsheet.

E

Seen on your screen, four summers in the video must be like this.

A

E

A

Not the green, no, the.

E

Company's a bomb 16-inch I added the link in the chat that was the one yeah example for the Bill of Materials yeah.

A

It's got a lot of difference.

E

Cushon about that a while back all to you the importance of having all that supplier- and you know different, linking multiple lengths can be informational because I mean we just need a lot of room, I'm, sure first, supplier links because all over the world are going to want to different sources. So yeah.

A

Yeah, we do on multiple sources for ourselves now, of course, if you take this all over the world, people have to do like one for each country or region. I would say, because for us right here, we have like five sources. Yes, this one is nice and that that's coming off like there's a page called BLM, should probably be just BLM with that template or BLM template no yeah.

E

A

Be om template that should be on a wiki, so yeah, that's it's kind of like the universal one we want to use and the one you see for the like, for example, on this d3 16-inch, it's kind of kind of a little different, because it's more about the CAD files here, so we're kind of using this for parts and descriptions and like the CAD files. So it's a little different, but yeah you're right, you're right we wanted we do want to use.

A

We do want to have a lot, a lot of suppliers yeah. So, okay, that sounds good Dixon. Do you wanna type in any other info? Regarding how you see the organization of them? You can.

G

Organization of just the parts in general, yeah.

A

So I mean I want to see. If we can.

A

My question is to all of us on that team is: can we start a file and start actually just throwing the parts in there and because the STL's can be can be manipulated, which is good? We can just work with those we don't.

A

We all necessarily need to redraw them unless they start taking up a huge amount of memory, so the the concept there would be if the cat, if the sbls are manageable in size, we could work with it. What is your impression for that? Are those all those files like how big are they all together? Let's see I mean with let's see on your spreadsheet they're.

G

Not too big I think I've got all of those if you look on the fixed recruiter library, so just looking at a couple of the STL files for the case, if you wanted seventeen kilobyte mean.

D

G

The larger parts are more like 686 kilobytes, so they're not monstrous.

G

Unless I'm, assuming that I got all those sizes right, I just took them from the wiki upload page. They should all be accurate, so I think they'll probably be.

D

G

I think I missed a couple words you you were saying you want to start a CAD file and assemble them. That's what you're talking about right, yeah.

A

Yeah I, you know I clicked a hell, yeah I, clicked on a couple here on this page. You know if we, let's see one was 100 150, let's see so like 50, let's say: oh yeah, you see you say that all there right, 70 yeah I mean that's going to start adding up quite a bit like 291 are hot and there are there's a really good number of them yeah. It would definitely benefit from simplification, though they are relatively simple. Already are their son Belize like?

A

If we can, you know how we broke apart, the Machine into modules. Last time, let's see, let's, let's, let's go back to that. Where was that index? That should be in our working document, which should be on the lineman film, an extruder page, there's the working document, so he broke it down into modules.

A

Is it like? Let's look at our spreadsheets? Are they yeah? It would be useful if we can so it's like extruder master part index if we had like module break down to match the module breakdown? Okay, so here's the working document. Where is that.

A

Or isn't it working doc, yeah?

A

G

um On page, two I think to see you viewing the working document on page two. The system muscles breakdown is what I currently have all the parts divided to in the parts. Library I don't know if those are the best final destinations for them, but for what it's worth my goal, this value.

D

G

I'm going to put up entries for every part on the build materials, whether or not we have any image or CAD file or simplified CAD file or anything forth. So the art library has an entry for everything so that we can start getting it and so that we can start putting them up there as soon as they're done. You.

A

Mean the assembled modules gallery.

G

Know just to get entries for each part, including the non printed ones. So, yes,.

A

G

The perf gallery, we have entry for all the printed parts and then a single entry so far for brass pushed Spain. They put up there and I'm going to have the part library complete as two entries for each part that in the build materials, whether or not we have files for them. Yet. Okay,.

A

G

Once I'm done with that, I can I can start simplifying files. If many.

A

G

We think that's the most prudent next step, yeah.

A

Now, what do you think is the level of redundancy I mean there's a really large number of parts of how redundant these? Do we think now they are, they may be like one or two here or is it like 50% or.

G

No, it's just a handful fits as far as I can tell there's not a gigantic.

D

G

Of redundancy- and so so it's we don't need to make a major overhaul of it. The way it is now, okay,.

A

G

Just a couple I'm, not unfortunately, I made a note on paper instead of putting on the wiki I'm, not sure which parts I was noting this like there's one where there's a whole, it seems optional, then something like that I'm sorry, I'm, not sure I should have put that on the wiki. You know.

A

G

It's not a huge amount of redundancy, no yeah.

A

Okay, so yeah, so that's a great first step, so we got all the individual parts, then potentially parts simplification. The way it's organized right now like, for example, big, you know, take a look at big box, enclosure plus hopper I mean we should be able to take a those loads, and you know like what I just said that should become one assembly right.

G

A

G

It'll, head you'll have a CAD file and images for each complete assemblies where you're getting it right. Yeah.

A

Yeah, like that's the big box there from hopper yeah.

G

I'm so I've been looking at that and I'm, not sure that we that, because the big box and the hopper, the extruder is between those two things, because I think the big box is the big box is return referring to the main enclosure that the extruder electronics are inside of yeah.

A

I think and so offer like the hopper right and also the hopper like where the actual auger goes in there.

G

Oh yeah yeah, that's true! For some reason: I was grouping that in with the extruder barrel, auger and flange, but that's not really. Okay, I see I see how that's going now, yeah, so yeah, well, wool, and but we'll want to make those with simplified parts yeah right, because you're new.

A

I'm going to.

G

Be printing out any parts from that cat file or what have you.

A

No, no we've got the printing files right, so we know we've got rat, so we just want to simplify. So we can manipulate this properly and have the whole thing in a manageable document. Yeah yeah.

G

So I guess there's two things to make that happen. One is simplifying the printed parts and one is coming up with I guess placeholders for, like the electronics and the motors and stuff that are the same size that we've mentioned before, but.

C

I think it might be helpful.

G

To give those two things because to separate people, because they're kind of two modes of working mm-hmm.

A

So, okay, how should we break it down, so we got can't see yourself, babe yeah,.

G

G

Probably, since my goal is to add, make entries for all of the parts and positions of the printed parts, it will probably make more sense for me to to also at that same time, be working on getting dimensions for those parts and then and then have somewhere else. Work on converting to STL files to free CAD file. Does that seem like a reasonable breakdown division of labor? Okay,.

A

And can we have go ahead, go ahead, yeah.

E

I think it's probably good dies as I understand. It's not that we're going to simply want to immediately convert all the SDF files to free cat. It.

D

E

Want to try to look at them and kind of put them together to check certain things measurements and make a general assembly if we can using the existing empty ml right, yeah.

G

But we also need to attempt wanting you to have be able to have the files not be as large through the STL files. Now I think is what Marcin was getting yeah yeah.

E

They're large, that ya know what first I keep hoping is that mr. Liman is just read well months miles, but if we eventually have to convert them all we'll have to do that again. Oh I see.

D

E

Hopefully he has the stuff and they can organize it. So we can. We don't have to do all that work because he should it sounds like he can export that stuff work. It is versions that we Nordmann, but if it's Holdings up we've got to do something so up. Okay, with doing you know more that pre-cut stuff up, so there's a lot of data entry to do so. I, don't know idiot reinstating tree everywhere, but yeah.

B

E

See on the next steps slide slide 11 the last line, I think I. Guess that's our kind of working document by the stuff yeah.

E

What kind of tasks we're doing so probably need to update that.

A

Yeah, okay, yeah.

D

A

Yeah right so there's a like on them.

A

The film missing pieces there's a whole bunch of work there. Yeah I mean that's, that's that we can say that's Dixon you're, going to create all those placeholders, yeah, well, I'm, very yeah, placeholders and you're going to populate them already with like say, mcmaster-carr parts or other parts or just simple drawings, like a motor as a cylinder. You know just draw it up quickly and freak out or whatever, or something like that or yeah.

G

I'm going to start with just my first task is just to create entries for everything and then.

D

G

Getting easier to get parts which will probably be the mcmaster-carr files, was there I'm, not sure? Was it I think I can't remember who's a bore, Kathy HECO was working on one of the spreadsheets and might have collected some files together already now.

A

G

Can but it's not the case I would like to grab those no.

A

That's on this, that spreadsheet is also on the lineman film and extruder page there's the two spreadsheets it's kind of disorganized here, but on the top there there's the vom, that's Abe and then towards the bottom. There's the spooler vom wait: yeah, there's B om extruder and spooler yeah um yeah yeah.

E

Mentioned separating files into the exterior of this Buller, so I started trying to do that more right.

A

E

I've got all right.

A

But are you working on them in the spooler spreadsheet that cassie started or you got another one going on I.

E

Have a master index, Reggie I think you were looking at that awhile right.

A

Right but that says extruder master index does that include the spooler.

E

Exterior part index yeah.

E

So yeah I think I've got a better one. Mormon elder.

D

E

I copied data from a copy dating from Cassie's materials and I'm still editing. Some of that. So what's.

A

The place for the master index for the spooler, if she's got the spooler spreadsheet there do we need both or do we want to consolidate. Or how do we do that? Oh no.

E

Materials well like most.

A

E

I make the availab material you see.

A

E

A more thorough file kind of like.

A

E

D

E

And the master index which to include some things from the build materials and then the I think it's defined one of these documents, yeah.

A

E

Plus length cat and the simplified cattle.

A

Race right right.

E

Some of the links from the week- yes.

A

Yes, so right so, can you embed the okay? We need to make that clear on a wiki there that this is it's not really be om its master index to make the distinction between the two and then make a simple comment there do M is follows the Bo I'm template where's. The master index includes mainly the the CAD files, correct, yeah, yep yep. So let's stop.

D

A

Can you clean up that Lyman extruder a film extra page to reflect and reflect that to be on vs. master index, so it looks like yeah.

A

Now, if that's the case, do we have a BLM spreadsheet started for the extruder itself.

E

I think that same I can see for the spooler, because threads.

A

E

Was listening on the next step page last time right.

A

E

I guess no, you probably need to work in the winery global I see Josephus test on the the wider before but I guess he moved on to some other names. Yeah.

A

E

Doing have not got done yet.

A

Right so let's take a look at that so.

A

Okay, so I was getting really clear here so.

A

So there's a list of next steps, but let's do like a task order like.

A

Right because we're kind of spilling it all on the Left column there.

A

So let's kind of get really clear on attack task order of what needs to be done.

A

So maybe do task order and then attach names to like in a sub task order. In this order of things.

E

Yeah priority list of what we want all.

A

Right all right, my.

E

Help done faster.

A

Okay, so we do know that definitely Dixon on the placeholders for every part, right, yeah,.

A

That's definitely a priority. Maybe second part cleanup. The Lyman filament extruder place with clear distinction between vom and master indices. Does that sound was that right or no okay, so wait I'm going.

A

So put a link to that clean up the.

A

I'll put a link to that. The wiki page.

A

With clear distinction between.

A

Vom and part index.

A

So BLM is clear: are we calling the master call it the master index or part index when we call it? Let's get clear on a nomenclature here.

E

A

You call it master part in desperation,.

E

E

Let's see yeah I call it the economy master part index spreadsheet, there's one for the external for this to the learner, so yeah master part in deck. Okay,.

A

Now, just the other question is because, like we have for d3d, we have a master part index and then, after that we have master assembly index. So do we want to craft er that go in to do a placeholder for the master assembly index? Okay,.

E

That's that's for the modules yep first are put parts together, yeah.

A

I think trying.

E

To edit doing you with more, we kind of define some of that together, we can go so I think it's the weekend brought up to what we'd already talked about. Okay,.

A

Okay, so we'll put you on that there so Abe.

A

Okay and then Cassie, what can Cassie do it this time.

A

Oh sorry, Dixon did you say when you create the placeholders? Are you populating them yet or that's later sorry,.

G

A

You populating the placeholders with the actual files or just creating those placeholders I.

G

Intended to create the placeholders and then start selecting the file, I have populated all the files that I have, which is the printed part. The.

A

Vault I get I, guess can Cassie like us. Can she help you with that, like you both actually do it or does that get messy.

G

I'm sure, if we coordinate it can be fine.

A

Yeah, let's try to coordinated, we got.

D

A pate because.

A

It takes a bit of time. We got to just get all those parts, indexed and populated I mean one by one. I mean it's like almost looks like silly things, but they matter at the end of the day, because you got to have them yeah.

G

I think probably the best thing to do is all start working on creating entries for all of them which shouldn't take forever, but if I can try and get a hold of her after this I can check down for an email, yeah.

A

G

That she could start tracking down the parts from mcmaster-carr or getting general dimensions of motors, and things like that that we could then populate the entries I make right away and then, when I've made all the entries then known to go first, but that way we're started on both things. So, yes,.

A

G

Tracking down CAD file would be her test now if I was handing them out. Yes,.

A

So my question on that is, if we're tracking them down or creating them, how are we organizing it? Are we putting those into the master part index.

G

So the the master part index will link to the file on the wiki right right.

C

G

I think what I'm going to do is I'm going to make the entries and then what we're going to want to do is name the files after the entry I make yeah.

A

G

Just upload them to the part library, and then we can link to to it there on the on the index. Okay, right.

A

It does but like, for example, my only concern is like, for example, if we wanted to say, Cassie can work today or tomorrow and and.

A

Like the parts aren't indexed yet with, in other words, the placeholders aren't set up yet like if she just goes to, she looks at her bill of materials, and she says: okay I want to do this motor grab the calf out. What, if there's no placeholder? What happens, then? How do we address it? Well,.

G

I think I think the best way to address that is to upload whatever part file. She does get into a zip file or just send it to me. I know we want to try and not send files over email, but then, when I create the placeholder I put those files up directly, while I created I'm, not sure what the best venue for that is. If a zip file could just be uploaded to the wiki just kind of at the top of the filament extruder part library, and then.

C

G

Download the zip and break it down and put it into the placeholder entries while I create them should should she get those done before I create them.

E

You were mentioned earlier, the network kind of at the file names, maybe just come up with kind of a standard way of naming the files they can be uploaded in each order and repeat, try theme that matters, because one of the names of the files are the same or you were kind of making templates and stuff and laying out the lengths yeah.

A

E

G

So if we look at your your entry in the acuter barrel or your flange sub assemblies, there's no image for it, but it already links to 5x8 in run bushings SAPD. So if I was that name gets uploaded, it will auto-populate, okay, I'm, not sure, on the other part, I'm, not sure how to come up with a standard that would apply to motors and PCBs and all of the different parts.

G

My plan was just to fake. However, it's listed on your gold material and then add JP, the 4s CSTB to the end I'm, getting out that if.

E

Basically, it sounds like that the name of the file as long.

G

E

Knows that if we keep the file names consistent and they populate automatically should be obvious and figure out an anthem, yeah.

G

Yeah, so as long as if the sorts of file name is what their entry on the Bill of Materials is or the master index, if we all just go off of that, it should be seamless and the only thing that changes is the file extension. So, okay, what we're like? What's the most complete list apart, would you say your Philips eyes.

E

No chance brother stop Kathy made, have the spooler data and I think that's that doesn't look is complete. Actually, your.

D

E

Against the numbering on the Oxley, I was mostly going off of the PDS, but yeah I mean girl need to be altered a little more clearly so I think that I've been doing the master index and trying to get that clear and, of course, that's going to clued all the plastic Institute. So private parts.

E

You think I'm nearly done with well the master into at least most of the list of the descriptions for the extruder mansion so that that's pretty good sources the names the spooler probably need to work on that a little more. That index is not not edited as much extruder connects, but okay, we'll then.

F

E

Before prioritizing the extruder first, although I don't have to do that.

G

Well, let's do that anyways inset, we'll just start with that, and then when the spooler index is complete, then yes, we want to that'll. Be our next step. Time, though, is the link I'm pasting in just to check. That's the master part index, you're referencing, guys, yes, okay, so I'm going to make entries for all of the parts based on that index of those what you've got in column, B is going to become, I might take like you've got the PID and then, in parentheses, you've got control.

G

Temp I probably will take those parentheses out, but otherwise all of the names in column B are to be M. 4, bolts, jpg and port, both tariqat so that'll be the source of all the names that we got sound good yeah.

E

That sounds good, so that stuff in the description, other description names that probably necessary, is just going to be more clear. So if it's in parentheses, it may not be necessary, although PID is very clear, I guess we can name it write it out. It's proportional and I know.

E

Through conventional device, I guess, but it's yeah- we might name some things better, but most of it should be pretty.

G

Good I, don't know what your availability is. You have time to make a quick look over those before the end of the day and and make any changes you, you think or I guess, particularly essential before I start making entries based on it. Yeah.

E

I was already working on that this morning,.

G

And I'll take.

E

A look back over that to edit it a little bit now. Centering insulin, that's fine! We should be able to get that ELISA names Thanks, pretty quick, yeah.

G

And I won't be able to start really creating entries until tomorrow morning, so that should work out fine, okay,.

E

Yeah and I know that primates I do bronze bushing earlier just to demonstrate, see how that would work, but ugly something's. Certain characters have to be changed so we'll just supplement them with what works for the week yeah and then.

G

And then I guess the process will be once we start. Creating images just go to the part library when you're trying to figure out what to save a file as and then use what I use is entry.

A

Maybe one comment on this: do you want to do like a prefix, since the file names are going to get confusing? Once we have more of this organization on the wiki, you want to do a prefix like FEX for filament extruder underscore F P X underscore PID at the X underscore voltage.

E

Regular sounds like that: yeah something.

A

Like that yeah three letter code, so Fe X and mmhmm yeah.

G

Oh, oh I, guess all conforming all of the problematic to rename a file on the wiki. Well,.

A

If you can rename it, you just start a new file yeah, you can't you can't rename things. You just got us upload. A new unit.

G

So should I real upload the printed parts and confirm Emerson's, those are I guess those are pretty unique. Yeah after we don't need the prefix orientation. No.

A

No I think um now for now, as long as we get we're organized well on that page, I think just from now on, just just for the future. Let's just start using the triple letter prefix from now you can leave the other stuff because, like for example like M for nuts dot, jpg or STL I mean they might be different, you know I'm for nuts, might we might be using different M for nuts for another project. You know so yeah things like that. We just want to start differentiating.

A

We don't have so I mean right now we're really starting to get well organized on the wiki and stuff like that, so we don't have much structure yet, but so I think this is a good time to start and just going forward just use these good practices. Mm-Hmm.

A

Yeah, okay, that sounds good, so mastering so just go back to just the clarity on the tasks this is like yeah. I think this is all it's all about, like accounting here, so okay placeholders for every part.

A

Yeah dude FEX, like underscore like that.

G

Okay, it's much easier.

A

To read uh-huh and then for them, then you can.

A

We could do like filament winder, like FWI, for.

A

G

Well, let's elicitation is prefixed to because I know there's a lot of different.

G

So have you looked at the precious plastic extruder? Oh.

A

Yeah yeah a little bit.

G

I don't know if that's something that you want might want to replicate at some point: yeah yeah, it may be a little more. There could be more than one filament extruded, so maybe LSX for the prefix.

A

Yeah yep, okay, I'll go with that.

G

Wrapping up one of my marine bodies not to build a plastic shop and he wants to get going soon, so he's looking at building some of those machines yeah, since we're still kind of in the process of working on this extruder yep.

A

G

So we'll go with that prefix underscore and then the name sounds good.

A

Yeah, that's good pop.

E

Spl Miller or something like R yeah, yeah,.

A

Keep it two three.

E

Thank you well,.

A

How about a la clase, Lyman, filmin, schooler,.

G

Okay, yeah yeah. That works. Yes, consist my lecture.

A

A

All right, okay, so placeholders aid gets all those BLM's as well as master part indexes down pat and also assembly index right and Kathy.

A

Can she start tracking down CAD files starting tomorrow or anything.

G

In tracking down a rough 1/2, CAD file.

E

Yeah I think that there's a few math mcmaster-carr parts where the speed in those files, some of the other stuff, is probably just going to be coming up with rough. Three cat I'll probably have to draw some of that yeah.

A

E

Most of those places, probably don't have cat files right.

A

E

Course you know there's the little part stuff like the bolts that should be needed. Generator I didn't really care for it about those parts of it and you know, and for Ultem stuff, are already pretty much available in the weekend tool. So yeah, that's easy, P to the ports and stuff I, guess just no, except to rough him up a little bit from general dimensions, just the expense. That way. We know how they've been together.

G

A

And then, let's see file, simplification would be something in order right now, right now, only the printed parts are indexed. She could, if she's doing, on tracking down CAD files and making them and simplifying them.

A

Simplification was something we could do like right now, so take the heaviest file, make it make a 10k version. You know or 20k version like yeah, that's I mean there's a lot of work there. We definitely need it so.

A

I'll follow up with her I'm, not right after this meeting I'll email, her about that, okay. So, basically.

E

There's there's been some instructions on that now. I know I read some of that, but I don't understand I, guess probably the file simplification, but I guess there's there's documentation about how to do that. Better now, right, yeah.

A

It's called the final simplification page on a wiki.

A

It's basically upshot of it all. Is you just seed that so we've got the the work flow as we seed the mat, we got the master index, the part library, and as soon as it's seated, we can start uploading stuff to that file. One is going to be the drastically simplified. Another one is going to be one, that's even more simplified without the sketches, so essentially like two files effort and then there's a third one, I guess we can say three one is a simplified two.

A

Is this simplified without sketches and third now the second simplified without sketches may already be without a sketch. If you started with part workbench, because that doesn't have sketches it's the simplest it can ever be, so is either two or three. The third one is the positional file. That means once you upload it, let merge it sorry into the dot working document. It shows up in the correct place, so you don't have to move it around. That's that's like the ultimate, but for now we don't have to worry about that.

A

We just worry about the first two, four first one which is like if it's downloaded from McMaster car. It can be really heavy so at right after downloading something that's like 200k or like a mag from McMaster car. Like say it's a detailed part. You know it's gonna, be a Maggert, a few meg. The next step is okay, simplify, so it depends.

A

It depends what file it is, but the general procedure is get the first file of the so there's the placeholder throw the first file up there as soon as you can whatever means necessary, then we work on simplification, and then we work on the positional positionally, correct files that allow us- because we assumption here- is that we're going to be modifying this until, like we perfect this and stuff, you know so it's so it's we want to start a proper paper trail for doing modifications in the future, because I can tell you right now that all the work we've done today has all collapsed in terms of modification a lot of times.

A

It was as silly as it was. A the file was hostage. What I mean by that is was like SolidWorks and nobody can open it by the one guy that was doing it or whatever. So so, we're addressing all those issues- and it looks like it's pretty complicated, but we got to do it.

A

We got to kind of learn like this overall CAD workflow, like really the file management process, so I think that's good, because that allows us to actually continue continue for, like time, I mean really continuing development, as opposed to you do one version and you kind of got to start from scratch. You do another thing, which is how we've been doing it today. I mean we got it. We got to get to the next level, so yeah.

A

A

Now, let's see where we are on the together. Is that clear, so cat Cassie? Can she can definitely start tracking down cat files now, because, if there's when there's no placeholders just start the simplifications of the existing stuff, maybe you're going to clean up the wiki page, Dixon you're, going to seat everything so I think that sounds pretty clear.

G

Yep, okay, yep and so I'll. Let start on that tomorrow morning. If you just want to have a look over the names on that index, then then that I'll just I'll get cracking on that.

A

What sorry can we take any any goals like? What's how long should take us to actually get those indices going, get all the part library seeded?

A

What are you guys estimating here.

G

I'm going to say Sunday at the latest, I should have all the entries for the part on throwing out the spoiler that I have the parts on the index we have completed Sunday at the latest.

A

Excellent, that's in a week week scale then, for the other ones to do the file certification. How long do we think that's going to take because I'm thinking of how do we tag-team later on simplifications? What is that a.

A

Couple of weeks with three people, yeah.

G

I'm not totally sure I need to look more in depth at the simplification documents. I'm not sure what that entailed. So I can't really contribute to a meaningful forecast.

A

There, mhm okay I, would estimate once if a part is simple. It takes you like half an hour to draw it out, but there's a lot of parts and we have to figure how they go together, yeah but right, but it could take between 15 minutes and like two hours, because.

A

You have to actually like- sometimes you might not know, what's important to in that file like which which dimensions are correct or what's what's what's important, but I think the figuring out part okay. How does it go together like if you don't know how we're kind of gonna be stuck scratching our head, so yeah? We can make a good prediction. um Yeah.

E

I was wondering about that cat stuff before I had seen people that seemed to some examples of using pre cat a little better where the subcomponents were obviously openal in the tree view. As you know, the parts all fit together, whether they're part of the assembly, and then the assembly is part of the whole of the machine.

E

It looked like it all fit together in the tree really well, and I was thinking that that was kind of the method that we're going for it seems like pre cat, or at least some of that product management design management. Stuff was, you know, people figure that out for free cab, but I wasn't familiar with the software and I. Don't know if that's what you were looking at in the simplification, more.

A

Yeah there's different.

A

It depends on your workflow like how are you you know what the purpose of it is, so your process is going to depend on that, but in general the one thing that is agreed upon as a CAD standard for free CAD is that you, you use the merge function all the time. That means, if you design something you're, not like copying and pasting or like working a single document, you're just taking individual part files and you're, just merging them into the final document, and you do all the work as low as possible.

A

That means, at the part level yeah, that's kind of the general thing just merge! That's the magic word is merge, means you've got a file, you don't like. Don't import, don't open, merge!

A

That's that's the deal yeah, so kind of train your mind to think along those lines. That means that assumes that we have individual part files, which is what we're doing right now. So we're consistent with the industry standard here, we're generating all the parts down to every single part and the additional step we're doing immediately is the simplification. Because of our distaste for how long it takes to open up CAD files, and once you get, you can simply do more with that, you can do instead of quitting at okay. I can only do like.

A

Maybe you would have two files, one for the film and one for the spooler I can guarantee you if you keep them small, you can of course, do both the filaments, cooler and winder for maybe even like a one that shows multiple of them in the same cloud like you, won't be limited because they're so light, you know.

G

Yes, you just found a.

A

Little out of a shark or something exactly so, it gets just simply gets us more power and and you're designed for the purpose that you that you need and we are going to need like I, like to definitely what you just said right now, my print cluster. It should all be in CAD, you know with all the Machine down there and then they're simplified, and we might need to go to the next level of simplifications. Once we get the entire machine, we can just say: okay, now we get the machine.

A

We make another simplification of the actual entire machine which we've never done right now we worked with simple files to make the machine. Maybe later we need to go the next step. You know stuff like that, yeah so yeah, but it's depending on the purpose that your you're working on so it seems like for now we were pretty good I just want to get to like I want to have I guess the way we should think about it. Okay, the in part index think about merge.

A

If we organize around merge, then we say: okay for any merging to start happening. We got to have all the part file so indexed and seeded, and we also know that we got to start simplifying because once we start merging too many files, they'll be too heavy, so yeah.

A

That's kind of the about yeah I just want to get my hands on starting that some, because, because I mean should be actually quite pleasant at the point where we've got all the parts.

A

Well, still the missing link right now is we don't know how they come together, but once we have all the parts we can actually start manipulating them in 3d. So it's going to be easy. We don't have to like look for it or generated we just simply: okay, here's download all the parts into freecad merging them, and then we can start making sense out of that. So yes, labels.

G

At that point,.

A

Yeah yeah, because right now the part that the trouble is it's like. We don't have those parts, we don't have the Lego blocks right now, so yeah clearly I mean it's kind of obvious, but it, but to actually do then execute the entire process is actually pretty complex. You know yeah.

G

And there's a lot of tedious work really.

A

G

Work involved so once that's done, I think oh yeah.

A

G

Start rolling itself up mm-hmm.

A

Yep yeah that sounds good, yeah, okay, so I think I think we're good. Let's, let's quit here. As far as the extruder goes so I'm good I'm clear on my ass, okay, excellent.

E

A

All right thanks vixen, thank you all and I, don't know if Israel just to wrap up with Israel I see you joined a bit late here. Israel. Do you want to pipe in on anything because we could get you going himself.

C

I'm not sure it looks like the yeah I, looked through your file, simplification and I noticed when you uploaded the x-axis.

D

C

Simplified version and compared it to my version, tour was much smaller. Well then again, I have to add so I guess: I wasn't clear on that up. 100% right.

A

Okay yeah: the question would be like: hey I'll,.

C

A

Ahead, go ahead, yeah! No! The thing is right now, given that we have that file the thing that would be really valuable, maybe.

A

Two things come to mind, given that we have the simplified axis, it can be used right now to model both XY and Z. Like all those right in a super, simplified version, then the next I'm thinking. How do we plug you into the next step here, and that would be one side that we have to do is the different sizes of the 3d printers.

A

So there's two things there one is simplifying the extruder and then second starting design. The different frame versions, like the third in particular 13 inch and 10 inch. Those two are: we've got all those frames, but we haven't. We don't have a complete design for how we would actually look.

A

Can we get you going on one simplified, extruder and to put it together, because, although the only thing that's missing for you to be able to actually work on making a 3d printer is the simplified extruder. If we've got all the accent of the frame, take the axes take a frame which is thirteen inch or or ten inch, and have you seen those DX steps of the frame or the frame page.

C

Not yet I don't think so. Yeah.

A

It should be transparent if you, if you look at d, 3d frame, should be transparent. What we're talking about it's cutouts out of flat flat metal, so you be able to start on just assembly. Take the 13 inch. Let's start working that 13 inch. Simplified version just start putting them together, identical 2d 3d, but the lens will be different and therefore you might and.

C

This is the intact right once we have the axes, we just need to put it together. Yeah.

A

Once you got the axes, you need to put the frame around that, but actually we claim we do that's what you've got the simplified acts. We can use that for all the x y&z since they're identical and then you got to add the platform and other things but little details, but the number one order of things is the the geometry, but you do need the location of the bed, which you can take off. Look how the d 3d 16 inch.

A

Does the bed and just replicate that for the 13 inch and and the goal is for the there's two questions on the 13 inch. Can we actually fit a 12 inch bed in there? No, it would be tied, you'd have to pull the axis on outside. So let's not do that. The way you can get an 8 inch if all the axes are on the inside.

A

So what I would say it's focused on okay, we got an 8 inch bed assume an 8 by 8 inch square and we've got a 13 inch size frame and see if that works, see how it works like what the geometry looks like exactly. That means draw it out in detail that you can show like okay. If I move the extruder it's going to reach all the corners of the bed, does that make sense.

C

So once once you get the frame around it, you want a man, make sure has enough space to move around yep.

A

Yeah and that you see just you know just that putting it together, like you had those pieces in real life, you have it in CAD. You can slide the carriage around to see how much range of motion that has then you can say: okay, I get I, get 8x8 inch print area out of that. So the question is: can you make it have an 8x8 inch print area when you use the 13 inch frame, yeah.

A

Is that does that make sense, or is it too complicated to kind of wrap your head around that? Oh.

C

Yeah I think it can make sense, so I think maybe getting it in getting the frame around the parts. Yep first will help and then, uh if I can fit that in like make sense of it, I'll ask you questions. It doesn't yeah.

A

It's like I think, step one. So the magic word is merge step. One is merge. Bunch of so you got the X x-axis throw in throw in like so. You got x, y Y Z. You got three four of them, so murder them.

C

Emerge also frame yep.

A

Merge is a bit basically you've combined all those and then, of course, you got to shift them around right, like you get there at right angles to each other, so you arrange them. You put them all into the document, then rotate and move them so that they they line up on the frame. Do that take one step at a time so take the frame frame file I, don't think we have a 13 inch in 3d CAD. We might, let's see Jose.

D

C

A

It's just but they're they're, basically squares, yeah, yeah, they're, cut out squares with 1.5 inch thickness of the square. You know to me: it's 13 by 13 and the inner cut out is 10 by 10.

A

In other words, 1.5 inch thickness of the frame Oh meander yeah.

E

A

Yeah frame I know Jose started on a complex version of that. Let's see equals a log. Let me see if he's got a frame in his document.

A

There's the frame there sorry there's Jose Jose log: let's see what he's got from it, he was working on a 13-inch before, but he was working with with the very complex files which was.

B

A

No, he did a different one. Actually, he did twelve-inch because we actually have a couple of 12-inch, which is uh the old stuff yeah just do the 13 inch from scratch. It's not a big deal, 13 inch frame, yep, so 2 squares and then extruded they're, 1/8 inch thick wall thickness.

A

So frame and four axes make them go inside each other, I'll be step on just so that will take a few hours couple hours few hours and then you'll get comfortable with the workflow of how you actually rotate and move those around and merge things and I think we can go from there. Okay,.

C

A

C

C

Executors, yes,.

A

So so frame four axes and after you've got the four axes, and then you got to simplify the extruder and see how it fits so that could be kind of like two phases. One is assemble. What you got and then simplify the extruder is the next step. So.

C

Then the the part plot, the parts for the axes are just going to stay. The same yep.

A

The extruder you can take because the overall assembly is gonna be so light you can actually use. Initially, you can use the heavy extruder, in other words the full file you'll, probably as long as there's just like one of those heavy files inside the whole assembly will still be manageable, but it'll start slowing down, like you won't get like an instant loading times. You know yeah, yeah, okay, all right, okay, sounds good, so frame for four axes and then extruder just three steps: yeah, okay, yeah, okay!

A

Well, it sounds on anything else, any other questions, Israel or anything else, because it's I think it's time to quit long, meaningful.

C

And I think I think we're good okay.

A

Sounds great guys, okay, so I'm going to quit here and next Tuesday 1:00 p.m. next meeting, so 1 1 p.m. Tuesdays is our regular meeting time see you then I'll take care.
