A

Recording everybody welcome. Everybody. I've got a lot of fresh blood today. This is good, so I'm gonna get started. If anyone misses any of this and there's some people that can't make the meeting right now, you can hear the recording this is being recorded with volcko screen, open source, recording software and posting on youtube. As soon as this is done. Let me share my screen and go right into the meeting. There's a lot of stuff going on perspective, yeah a little-little perspective.

A

First, the workshop is coming up on April 29 and at factory farm in Missouri. We've got three people already signed up, not bad at all for the first week and they given, given that the first week is typically the slowest right after the posting kind of picks up the week. Second and third, but the goal is twelve people, hopefully as many as 24 we can handle 24 people or so and that's going well. The design is complete. The build is like you see back there, that's the that's.

A

The 3d printer I'm gonna be prototyping the other versions, which are the twelve and eight inch versions. So I'll be posting some videos on that. In the meantime, let's talk about the team, okay, so we're recruiting ose developers. You can go. Let me let me share my screen now and let's go to the meeting so sharing the screen and let me go into the presentation. So I got the presentation so as far as the team we're recruiting- and you can join that if you go to the OSD devs page here- you have the invitation.

A

All of you have become Aussie developers, bypassing the OSD free cap test. Free cat is the main tool that we use here at one of the main tools for development and documentation. Now welcome to. We actually had a flurry of five new people join the team. So this is these: are the team stats so hopefully, the week after this? As you see here, this numbers gonna have a bump little continuous increase.

A

We started essentially in February with a team of one or two we're building the numbers, and this is always see developers as opposed to ad hoc development, we're getting people to pass the actual test to make sure that they have a basic skill set and commitment to work in a project in an effective way. So right here, what you can see is that's the number of people. What we're tracking is the number of active developers keyword being active, so why is there a drop here? Well, person didn't drop off the team.

A

A person may have not done a work that that week or may have not logged their hours. What we do is we track our hours, so we see how this open-source product development pipeline works, as if others want to replicate it just to show our record, because if we can measure it, we can improve it. We can. We can get this velocity of increasing the team numbers and team effort we're here.

A

The effort is shown happened to my mouse. My mouse died on me.

A

Pardon okay- happen to my mouse there. It is okay, my mouse is back up: okay, we're tracking both the number of developers in blue and the development hours. The development hours are shown divided by ten. The weekly requirement for the Aussie devs is ten hours per week. So what you should see is that the hours number divided by 10 should follow roughly the number of developers, so each developer gets one unit, one unit being one unit should be put in every week, which is ten hours of work.

A

So that's how it works and there's a for the new people on a team. You're gonna get a welcome email which describes how to do the timesheet. The timesheet is on the wiki. Everything is on the wiki, but the timesheet is on the wiki that timesheet the page called timesheet, where you simply fill that out. Just one note on it, the filling I know Hosea did this, but the filling is worked for that week. It's not cumulative, so you basically say: what's your name, what's you what you worked on and how many hours you develop?

A

You worked on a development team. It's this week: it's not cute overall! It's for that week. Just make sure you do that and then break down the tasks for the working hours. Okay. So let's get to the write to the topic of today. So so, as far as what we're doing on a 3d printer, you might have seen the advertisement on the. If you haven't go to open building Institute org, the video for the 3d printer workshop is there under upcoming workshops.

A

Now, what's the current status, the current status is producing documentation for the build now. One thing that facilitates that documentation has exploded, part diagrams and that's the main theme of today so exploded part animations. It's a feature that's found within free, CAD and accessible very easily. What I did is a quick sample here and free CAD, where you download the oh yes, so let me share the the presentation. The presentation is on addy 3d.

A

So check that out the presentation that I'm looking at please you can follow that the notes for this meeting. You can see the background on the exploded parts. Animation workbench, you download, that put it in the instructions are here, explode parts animation introduction. Basically it allows you to put the explode part animations. The good thing about that is, while I have built the the 3d printer here and I can take real video instructionals.

A

Other people can't if they do not have the machine, but you can do quite close with exploded, part animations. They allow you to produce high quality assembly instructionals using a distributed team. If you have the CAD file. So where do you find the CAD file? Well, the first thing is: if you look on top on that page, we can feel free to go there and you can see the sizzle reel for meaning just exciting. Indie 3d well not be 3d, but other animations of exploded parts.

A

So you can go to the D 3d part library or d 3d integration page, which is which has the files that we currently have in free cat. You can start downloading them if you go to d 3d integration just to get you oriented when I click on that you see this exploded. Well, there's this kind of a diagram here. What you want is one is the overall assembly file which is up up in the corner.

A

Here you can click on that to download the file or you have all the different parts as modules, so you can download that so, for example, here I downloaded the universal axis one of the universal axes.

A

That's where you get the files so download the software added to your free CAD by the instructions that are shown here. The procedure for downloading the and the exploded parts animation workbench is here, so we can take a look at that and it's good. This is pretty cool. Actually, it's very easy to use and just to demonstrate very quickly. I have the installed the Explorer part animation. You select it so expect exploded assembly. Then you can play it.

A

So actually, what I did is just very simple, just kind of splitting out the parts one by one and then you can record videos. The cool thing is, you can, actually, you know, rotate everything as it as it's moving.

A

So that's that's pretty nice nice videos can be captured. You can see that in 3d and therefore you can make videos of how things come together, and this is just a demo, but the idea is- and it actually cried at least I have freak at version 0.16, it crashes all the time, but it's very the instructions for that are very simple. You.

A

You click a face, for example, that one we're along which you want to move and just click this blue button here and it moves it see it moves it towards that direction of any face. So, whichever way that face is pointing you will see that happen, that motion happens, so it just crashed on me. So maybe it got better in version point one: seven, but I'm just saving constantly, because at least there's something some artifact where it crashes all the time. So, okay. So how do we do the procedures for the the 3d printer?

A

Take the download the file of interest? So what we'll do is we'll break down like in page seven? We would break down all the priority modules and to divide the work person by person, so we can work on things in parallel because the the device is made of different modules.

A

We divide the modules, you take your module, you explode the object as needed. You can also vary the speed extent, an order of the explosion, but that that you'd have to learn I didn't we want to put together a nice instructional that shows how to do that. You can watch some of the instructions length this presentation, but and then the bolts, rotate and stuff like that, so it looks nice. So the second step is a recorded voice. Over of the step by step procedure.

A

Now the critical part there is the step by step procedure. Now that has to be accurate and and well proven, those are actually not written and that's our next step. So as soon as this, this meeting is over I'm gonna work on doing those and other people can also do those, but those need to be pretty exact. So we know we have some instructionals already that have been started.

A

You can go out on the d3d log page d3d log is just exactly that: d3d log, if you look at the title d3d log, but that has our past meetings links to the all the video recordings. Unfortunately, we missed the last week's, so you have different videos of the previous week's meetings we missed the last week. They didn't record the voice right now. I do have the voice recording.

A

Let's close this so so step by step procedure is the next step which we want to work on and then voice. So I'd like you all to to get on this task and and get some voice training or go at it and put a length of voice training. If you want to learn things about voice because voice is important about a hundred thousand years ago, people have gained a voice about 5000 years ago, we learned to write in the 1990s.

A

Wiki's came into existence which allowed people to collaborate and recorded knowledge, and then the 2000s Google Docs appeared or cloud collaborative documents appeared. So we can now work on these collaborative documents that we can. We can. We can work together and the latest and human evolution is the possibility to make collaborative video edits. So this is this is what's here, so voice voice is very important. My point communication is very important.

A

We take that very seriously at open source ecology because you can have all the great work, but if no one finds out about it or if you can't teach people quickly, then it's no good, and so the idea is the voiceover and the instructional should be rapid, quickfire no dead space. Like you see my free CAD 101 video, which I humbly claim is the best freaking video in the world.

A

But the idea there was zero dead time. Every millisecond is precious because because if a million people are gonna, gonna watch that video, even if you have one second of that space- that's hours of time wasted in people's lives. So that's the idea, so you have to describe every step be rapid. The tight edit is what we want, so you know kdenlive a little bit. You can get better at it, but here there's the the freak. Add that exploded part of the diagram workbench you can use kdenlive to edit the video.

A

So we record it recorded using some kind of a recorder. I. Think.

A

Audacity has it so sync after you create the explosion that matches your voiceover, take that into kdenlive and edit the video as needed to make make 15 second chunks.

A

15 second chunk should take you like an hour to do 15 seconds of actual real edit, like real high quality. That should be something that would take an hour, so the assignment for this week would be to to do that by starting with the with priority modules and breaking it down to people for people to do them, and then, when you do this further break your module into 15 seconds sections.

A

So if your thing takes like say a minute total like for the total instructional break it into bite-sized chunks, let me explain that during the workshop, what we will have is a looping video and then the workshop everyone will build in parallel. We are going.

A

To build as a team in order in order for everyone to finish what happens is that as soon as any person is done, they help the people that are slower, so it will have as video video monitors or monitors in a workshop, and then it will loop constantly through a sequence that will take about 15 minutes to build, but the video that you actually use to get that 15 minutes of build time will be about 15 seconds. So it's about a second 2 minute expansion from the video to the actual build process.

A

What we found in the last word, this is what we found in the last workshop, that a lot of people would lag behind and they would never catch up and then we'd have to go back to them and do like all these different steps at the same time, instead of everybody helping each other. So we're learning that if we can help everybody go at the same speed, we can do a faster build in the extreme manufacturing process. So the point is the last person that is done.

A

They should have the entire team helping them finish, which means that the more the last people that get left behind they get swarmed on by the rest of the team and then it gets finished really fast. So that's the way we're designing this workshop to operate, so we can have incredible, build fun and velocity at the same time. So that's a little bit about that, so so, outside of that that's kind of all I have on what we have to do.

A

So what we have to do is pretty much spread the work between different people and then divide the modules up, download the modules and coordinate that carefully after we find out a little bit of update on what's what's happening from last week. So from last week, what we've been doing as we've done pretty much the the 16-inch version of the 3d printer, but CAD was complete.

A

Last week we were working on a 12 inch version because we're using nested frames like if you look at our designs on the d 3d wiki page we've got nested frames like the 3d printer. You see back here, there's cutouts from the insides of that that makes smaller 3d printers. So what we're doing right now is 16, 12 and 8.

A

In fact, I just got just now: I got new metal but I'm, exploring 16, 13, 10 and 8, so actually getting four sets out of one set of cutting of metal, but we were working on a 12 and 8 inch version. The 8 inch version we're calling the d 3d mini. It would have a 5 by 5 inch print surface. So, let's, let's get a little update on where that stands, so so Jose I know, we've been working on a 12 inch version. Maybe you can fill us in where we are.

A

We don't have a manual on a team here, he's doing that the 8 inch version and that we got to finish up because I'm gonna be prototyping that, like tomorrow this week, so that we can get more videos showing how we build these things. All together. Jose fill us in on where you're at just quickly can you speak.

A

While we can hardly can hardly hear you there.

B

A

Might be a little better if you set your settings to the limited bandwidth, go to audio only yeah I think we can hear you go ahead.

B

A

We're gonna have to go yeah. Let me see not yet.

A

No I can't see you seem to be able to see your screen. Are you sharing it.

B

A

Okay, so so you're talking about April, 10 downloading yeah. Let me share my screen, then again.

B

A

I'm, going to Jose's large sofas, a hose, a log, you can find it on the wiki and download the April 10, the 12-inch version, one. There correct.

B

A

Very nice, so the second link there, integration of 12-inch version.

B

A

Change of three: no sorry, okay, all right! Okay,.

A

B

A

Let's see eight page 18.

A

Okay, so page 18 we've got so. Basically that's the design, we're looking at the extruder carriage the way the extruder, the 3d printer extruder, sits on a carriage, so limit of distance. You can get, doesn't work, you're, saying, okay, so that's how it would be.

A

Okay, so that's: let's.

B

A

Old, so this is the new stuff. So so what's the conclusion, the conclusion is: to put it underneath, like your show.

B

A

Okay, now the only thing I can say.

A

Yeah, it should be magnetically mounted I from what I see it's not.

B

A

Yeah, that's um no altogether! The idea is pretty good, so just to check in on us. So with this like say, this works. How much of the frame do you still need to need to do, because we pretty much want to finish up the 12-inch version and see if we can get you also going on the exploded, part animation instructionals? How much do you have to do on the 12 inch frame version for the overall design.

B

A

Okay, all right that sounds good, so I'm downloading the medium-sized version right now take a look at that. Anyone else can do that. This is from Jose's log, okay. So a couple of notes here, I can assure you the magnets are plenty strong.

A

Each one of them does like five to eight pounds like it's hard to pull it off by hand, so you don't have to worry, because, on the on the mount I would like you to do the magnetic mount and do the same hole pattern as before, because that works really well and then the other part is I.

A

Wouldn't go with you have those four screws there you can make it support just make it support with a clampdown screws, because that's just easier to put together.

A

If you do what you just showed there, that means you would need to add another type of screw to this assembly, a longer m3 screw, which would increase our part count by one and we're being very vigilant about how many parts we're using. Currently, we only have three screws total on the assembly to make this whole thing work. So we don't want to add more because then we go nuts.

A

So can you yeah I mean that's the right idea, but but please, if you can do the magnetic attachment and just do the pinch on the sides so that you hold the motor so maybe extend that that's support for the motor a little more. So it's supporting the bottom. So it's not overhanging. So much yeah.

B

B

B

A

So what you, what you're asking for is the part library of all the accepted parts correct.

B

A

So we do have a page on the wiki called so I I started this recently and it's called d3d part library, and we want to put all seekers yeah. Now we get more people, we want to organize everything better. The best we have so far is that d3d integration page, but here's the part library so on this page come it's not moving up there. It is so basically we've got this page and you can download and click on all the different parts that we're using. So we want to basically put up.

A

This is basically a gallery of parts. I was just putting up the frame here, but what we want to do is have this as the approved source of all the good files. So you guys can post all the ones like yeah, for example the extruder mount that should be a part here and so forth. So we want to put that on here. All I can tell you is that where that file is is going to be, who did it and who did? It was a manual, so you go to a manual log.

A

I'll put paste that link for everybody. There he's got a lot of the different files there. So that's what we want to do, but yet so the the page called d3d part library, that's in progress, but that's critical to here, because the workflow is and I'm gonna go back to the document here. So so a little bit more about the steps so I'm gonna just talk talk about that. A little more fine fine-tuned, instructionals here so so put part two so download so for each module. The ideas for the export part animations for each module.

A

You would okay, so Jose I think we're we're done on the 12-inch version that you can make those upgrades just to wrap that up. Okay, so so so moving on for every module- and this is this- is talking about the 16-inch d3d distributive enterprise 3d printer- for every module download, the the correct part.

A

Parts from the d3d part library, wiki, page, okay,.

A

And then so, you can be working at different levels like if you're, putting together an assembly for just say the carriage piece versus like the entire axis, there's different many different parts. So, depending on what you're working on you, you select, the appropriate file from the library and the the library needs to get updated, because right now.

A

Most parts, I'm gonna, put a note there. Most parts.

A

So I was looking at this this file here. Most parts are currently.

A

At the d3d integration page or.

A

Manolos log: that's a manuals log, okay! So so what I mean by that is, let me see so let me put this free CAD.

A

A

Okay, anyway, my freaking sneezing up here select the appropriate file and then the script is the next step. So that's what we have to work on as a team and what we want to do is allocate the different parts to different people. So.

A

So I think what we can do best right now is: let's see, allocate the different different activities to people. But let's check in on some kind of jumping around here a little bit but I guess Jean Baptiste. Do you have any any report from the latest? You did on the documentation any any more work that you've done. Err.

C

A

So that's also: okay, let's see that okay.

A

Yeah all right, yeah, that's pretty good, so that's the kind of stuff we want to be doing now. So we have exploded. Part diagrams like this, but these are not animated so that the goal of the animation is to go a step beyond that and make it like a video that we can actually play. So so, whoever does these videos we're gonna play them during the workshop as real instructional. So this is serious work. This is not anything trivial.

A

This is a lot of people will be looking at these and if we put them into kdenlive, then we can continuously actually edit those files or update those files, because we'll have all the source code we'll have the free, CAD files will have the instructionals. The text like whether it's instructionals like this or whether it's the actual plain script, a very tight set one sentence after another, but yeah totally editable for future versions, and that's pretty good.

A

So this is perhaps the most complete a complete instance of what we have here like, for example, the magnets tell me the status of the magnets you have to you have to make it actually complete. I, see you're missing a couple right, you're missing a few right: okay,.

C

C

A

That's correct the carriage slider should use should have so. Let me let me zoom in on that and actually explain this to people, so this is actually the best working document here. So if I zoom in a little bit on this, this is the carriage. This is the place where the motor. This is sorry. This is the one where the motor attaches, and this is where the idler attaches so on the carriage one.

A

The magnets are there like in the corners 1, 2, 3, 4 and then in the two middle ones: 5 6 on the end, once they're on the edge ones and the middle ones, because the the closest then one won't actually be on the middle and this one. These four are on because those will be the ones that over the middle, this one is actually would not be over the current metal frame since the metal frame ends at about 1 &, a half inches like about there.

A

So that's the pattern, but the idea is now to take the axis and then start working on it, and so first you want to attach the mat. Well, you actually don't attach the magnets first. Let me go through the general procedure. What you do is you take each of the printed pieces you put in the bolts you screw them in together.

A

Then you put in the rods, that's the second step, so you have before I'm sorry before the rods you have to put in the bearings for the rods, so the bearings go inside the carriage there and you can see all of this within the the CAD model. So this is something you can figure out.

A

It takes both thinking and then just looking at these diagrams, so these four linear bearings go inside the carriage slide after you have the bearings in and the bolts in then you put in the rods once you have the rods, then you assemble the motor piece. You clamp that together and put that onto the rods and put and then put the idler piece, clamp it together and then put it on the rods, and that way you have the you're.

A

Basically, at that point in the assembled carriage assemble the axis, then you have to put on the the height of the stepper motor. You just put that on with a small four bolts.

A

Oops, the small four bolts, yeah they're stepper motor there should be by the stepper motors actually not shown here that should have the small four bolts for the stepper motor I. Don't see them here. So that's another thing. That's missing!.

A

Okay yeah, so after you put this sandwich on you, first put in that the pulley onto the motor you put the motor onto this motor carriage piece and then, after you have the motor on. You want to make sure on the other side, as you assemble the idler piece you put that idler inside, so that the belt can get on it. So after you've got the the drive system there, then you insert the belt now the belt is a linear belt and then the belt is actually pinched inside the tooth groove on the carriage.

A

So if you look at the detail on the carriage, it actually has teeth on this part, so the belt goes in there, one side through the other, and then the other belt goes in from the other side and so forth, and you have these two pegs. So what's missing there. Also for you, jean-baptiste is the the pegs which are after the belts go in there. They punch in and you can see that on our Facebook page I showed a detail of that, but it's actually quite tricky.

A

The procedure for for putting in the pegs there's nothing hard about it. It's actually very elegant, but it has to be done in the right order. I need to ride that out carefully because you can logic it out, but it's a little trickery. So so that's that so for now what I would suggest then, just so people get started with assembly animations. So that's, basically how one of these frames go once you got the frames and magnets, so the magnets go on you goo. They actually go down with Krazy Glue.

A

They don't come off, so he put in two magnets and you have to hold the magnets down for like 30 seconds, because they're gonna jump out like, for example, this magnet and that magnet, if you just leave them alone, they're probably jumped to on each other there they're, so strong, so you have to hold them down. Is the idea. So, once you put down all the magnets, you have to hold them and so forth.

A

But then that's pretty much it for one of those frames and then once you have the frames, you have the sorry of the frames, the axes. Once you have the axes, then you put them onto the frames by magnetic attachment and then you screw them together. So what I would suggest for now is that each of us get a little piece of this action here. So whoever is on the on the show here we should say: okay, let's do a tiny piece for everybody.

A

So say we should divide it down to as little as okay for the x axis or not even before the axes. We have the actual carriages, the the printed piece, sandwiches, the. What do you call them? I mean the carriage the axis pieces axis plastic pieces, so we can call axis motor side.

A

That means you're attaching the motor motor to it. Second, one is the carriage side to which the to which the extruder is attached. Then you have the idler side. So each of these could get an exploded, part animation, and we should start with that. We should perfect these get people practicing and once we've got those going, we can import them.

A

I haven't tried how you import explode apart, animations into other files, but if we, for example, have the axis motor side and that we import it to make the whole axis, then I think the animation should be imported.

A

At the same time like you can, in other words, you can build in animations at the primitive level like the axis motor side and then, if you insert it into the x-axis once you're, building the x-axis from individual parts, because the workflow is typically to make an assembly you just you just import individual parts, so those parts should have the animations imported along with the part. That would be great. So let's do that. Another piece is the extruder.

A

Another piece is the extruder: is there so it's already, but that's a pretty primitive piece. There's the end stops right here. There's the frame cable chain wiring so now, cable, chain and wiring are kind of complicated because they got so many pieces. That's maybe for advanced people, but for these we can definitely divide and conquer on this. So, okay, who wants to take these speak up then, so we we want to divide it as finely as possible for everyone who's on the team here, so who's who's gonna do.

A

Who's gonna do what.

C

A

A

Okay, once you do the motor side, let's talk about Chaz Chaz is joining the team, so we talked about a little bit about the universal controller and that's actually, let's talk a little bit about that, because that's one point of division but I think Chaz II, you you in the meantime, while I give the instructions for that.

A

Maybe you can sign up for that, but I sign up for one of the freakout animations, because that you want to give that practice if you haven't practiced it, but idea on the universal controller is that we want to make a scalable analog of the ramps with the ramps board but make it such that can drive any size of a stepper motor. So trance is gonna work on that and we can talk. We can talk about that Chad's a little later.

A

It's not so important for now, because we can take the discussion offline, just the point being that for the CNC torch table and the larger speedy printers that we're going to be building we're gonna need the universal controller which can handle more power and bigger size machines. So that's the idea there, but outside of that out to that aside, Chaz you want to take on one one of these pieces. So you learned this part because that's gonna be critical for access outside. Okay they'll be great! So try that who wants to do the idler side!

A

We've got Roberto. Welcome to you! We've got Abe, we've got lash low. You guys want to take on and Jose Jose you've got some work to do on finishing up stuff, but Jose. You think you would have any time left over this week or or save the save it for finishing the twelve twelve inch version.

A

You guys, by the way, can edit, let's see the sharing documents on this dock. Here you can find and view it. I'm gonna make it so you can find an edit, so you can actually put your name on on this. It's a freely open, editable dock and it's actually okay to make these completely open. In fact, whenever you share docks, they should be completely open, because if, if someone say once the only concern is someone wants to trash it because it's open anyone on the internet can see it well, it doesn't matter because file.

A

You have see revision history. You can actually look at the revision. History. I will pull up all the previous versions of someone hacks this you can actually restore it to any former version. So you have to worry about people hacking, your documents, so that's the idea. Well, you guys can now actually edit this document, so you can feel free to put your names by whichever one but I'm, not getting any volunteers. Who wants to do that? Let's see so Jose you want to do anything. Are you gonna be busy on a twelve-inch? You think I.

A

Didn't hear that, but if you can go into this document and put your name by what you can do so the document there is.

A

That's the document right there prioritize the twelve-inch revision, okay, okay, so prioritize the 12-inch version. Okay, so I think I'm gonna start allocating here so idlers side. How about Roberto? Can you take that perhaps extruders? So we know that Cedric is working on that he couldn't make the meeting today, but we're gonna allocate the extruder to Cedric. Now this is just the pretty primitive parts. Now that the x-axis means the entire x-axis, meaning the axis carriage idler in other parts. So that's getting a little more advanced there. Who wants to do that?

A

That's just a little different.

A

Let's see I'm gonna pick some names here, so Abe Abe are you gonna be able to do it? Do some some of this I'm gonna put you down for the x-axis and y-axis and z-axis. Those are all slightly different. I mean the y axis. The two y axes are the same, but all together, they've got a few little details that are different, so there's Abe and then lash lo, you think you could do that.

A

Can we allocate that I think that's what we're gonna do.

A

Silence is acquiescence okay, but we have some more parts that are outstanding here, so these are pretty much people got covered on those we got people coverage on those and these ones are still to be done by others. So maybe we can see if, for example, we can have.

A

The manual do that one heated bed, I'm gonna, see if Brian I know Brian was out for an injury sometime, let's see if Brian is available and then and stops and other people, let's see so that's about see actually Emanuel like as far as the wiring and cable chain. It would be nice if we can get the cable chain constraints such that if you move one end of the cable chain, the whole thing stretches out without having to move the individual parts.

A

The cable chain is a hole connected chain, so we want to that's a little more advanced in terms of free can, but we can design it such that you constrain it with the circular constraints that if you pull on one one link, it will actually stretch out the whole chain so actually, next week, we'll continue on the explode apart. Animations and I'm gonna see if we can add the other workbenches to free CAD, which are things like there's an animation, workbench and there's also fabrication drawings, technical drawings creations.

A

So we probably what we want to do for next week instead of getting into the animation we might want to get into the technical drawings section, because it was also be very useful to produce part drawings with all the dimensions, labeled and everything else, and that's you can do that in a professional way within free CAD and you can import your own title block. So I think that's probably what we want to learn next week unless people have other suggestions for the learning perm, because the idea here is, we teach each other.

A

We learn every week something new on this, but okay. As far as the people concerned, we've got six of these allocated and we're gonna try to allocate a couple more of these to the other people on a team if we can but yeah. This is good. That's I mean that's good for now we're actively recruiting so tell your friends about this, and hopefully we get more people joining the team, but other than that. Let's see what are the questions? Maybe we can open it up to discussion and questions.

B

A

So we need to work on a part library and making sure all the primitive parts are available. So what I'd like you to do is if you can just email me a list, a specific list of outstanding parts or set up placeholders within the library you can create one of these placeholders like here, it's a placeholder for the frame the frame hasn't been uploaded here. Sorry, let me share my screen again.

A

The best thing for you to do is either just email me with the specific parts yeah we got to finalize them and find them on people's logs. This is okay.

A

Okay, I'm sharing my screen again Hosea. If you go to the d3d part library, the best thing to do would be to seed those placeholders for the specific missing parts, because here we want to get down to each an individual part file. So, for example, I want to make one entry for the metal like bolts rods, so have one file that you can pull down all the bolts and rods and other metal pieces. So Hosea.

A

If you want to seed that as individual files and define exactly what's needed in those files that would help it would help it'll be the best if you just went to the d3 deep art library page on the wiki and start, if you click Edit you'll see the syntax for the gallery. It's just basically the syntax. There is you'll see if you figure it out, it's a gallery Tagg and then you have the different entries. The entries should be separated like that. That's that's.

A

Like one entry, we've got like one two, three, four five entries so far. You can see them see that what the syntax is like for the wiki markup. So you can actually add your own here. We've got five things right now, so yeah. If you could do that. Does that address that issue, because we got to pull those parts up and make sure everyone's working with the right right right.

B

A

Yeah I know what you mean so.

B

A

We want to establish a best practices guide for how each of these files are structured. So we want to start that and do that. You can start that we haven't really published that yet, but we want to do that. Definitely, standards and practices and I want to show you what I mean by this. Just by going into this one sample file like, for example, when we create the library what we're promising to the world is a construction set. So what that means?

A

If we've got our library parts, you can take each file so say that you know the motor side of the axis, but you can also modify it now. How do you modify it? Okay, what happened to my freak out here?

A

My screen dropped out something's happening here, but basically the idea here is that, within this like, for example, this is the idol, the the carriage right here you have like my freaking- crashed here, I'm doing too many things at once, but you, if you click on the sketch anything that says sketch you'll get to the underlying sketch and it will allow you to actually modify like, for example, the size of the holes and everything else.

A

So that's you can get to the underlying sketches when you change the sketch, like, for example, I added another magnet hall to this, and when I changed the sketch, the actual extruded part appeared properly. It showed the new Hall already because, though the extrusion part was already done on that sketch and if the sketch is updated, whatever was operated upon, that sketch also got updated. So that's that's kind of what we mean by the Construction Set, yes, but but best practices and and specifics on that are definitely valuable.

A

So so what I will do right after this meeting I will continue to put parts up. You can start playing with the actual.

A

Well, for example, like whoever's got the access piece you can put together that access piece by making a sandwich out of that, putting the bolts in there that you can do already and putting in the nuts in there. So you have to go to the download the available files. As we said, we have at the d30 part library and d3d integration, so between those two you can start getting oriented as far as where all the parts are and they are going to be put into here.

A

So you can see all of them like, for example, the right y-axis here contains the bolts and things. So you can. You can copy and paste components out of the files. The best way to work with free CAD is to import files.

A

So it's at this level here for the part library you want to have a file for a separate file for every component, and now that's not too bad, because the entire d3d, as I mentioned it's only 40 unique parts which is a great low number. It's not hundreds of different parts. It's 40 unique parts altogether. So that's it so I think that's about it. For for what I have to say today, people who are joining you'll get a welcome email.

A

First of all, welcome to the team. My new open sorcerer's as far as the weekly timesheet goes make sure you fill that out every week, keep track of your work, because this is really valuable for learning for the project. As far as how this open source product development method can be replicated by others, so we're developing something novel here in terms of the volunteer development efforts.

A

Well, that's about it for me, if you guys got any questions. Otherwise what I'll do is I want to follow up on this meeting and once all the different parts are up here. I'll email, you, but what I'll be doing, is working on that right now, so that we make sure we have all the individual parts that make up all the exploded part animations, but in the meantime you can start playing just download explore part animations workbench start playing with it, and you can see the sample file within a document.

A

You can open up my sample document right here. Let's see where is that sample document, here's the sample file on page 5 I actually uploaded a new version of the axis with some of the explosions. But it's it's relatively straightforward to learn and once you once, you learn the basics, go right into the work and check off as soon as you start, you got to start your work. Log I think most of you have done that make sure whatever you do.

A

You just keep looking and keep putting stuff up on your work log so that it's transparent that you've done stuff and, for example, towards the end of the week or you know today or in the next coming days.

A

It's if I can look at your work. Log I see nothing is happening. There then I'm gonna say hey what's happening. Are you? Are you getting started? Alright? So it's a good feedback to have that transparent reporting, as far as where, where you're out are in progress, but as soon as you have something publish it to your log and also one of the things you want to do is sign up for on the it's called the Aussie social network. But it's a developer's network and it's the we have the 3d printer group on there.

A

You'll get a welcome email with all these details, I'm just giving you a preview, but the network, its network, not open source, ecology, org, and if you go to the 3d printer group, so please set up an account there and post your comments or reports there. So so in a 3d printer development group. As you see here, we've got. You know, posting various different things, various updates and questions and comments. So that should be our discussion thread for the the working team and also feel free to use the OSC workshops.

A

Facebook group, because that's that's, got a huge audience as far as the Aussie social network. There's hardly anybody on it. Yet we're just starting that, but you can feel free to to get an account there and start posting on the 3d printer development group. That's an open access group. Anyone can join that so feel free to join that, especially since you're a developer, and you can post your comments and questions there.

A

So with that said, I think we're pretty good to go. It's exciting to learn the D 3d assembly. Animations, that's gonna, make things you know just basically adding the skill set upon our repository of free CAD knowledge, so that eventually we can produce a very high quality, free, CAD education course for people. So people can just learn faster because it's really painful right now to learn from all the freakout videos out there, because there's there's a lot of confusion out there.

A

Not the documentation is lagging well behind we're a free cat itself where its capacity is so we want to help undocumented free cat capacity. Okay, but that's about all I've got for now any questions. Anyone want us want to say anything.

C

I'm controller yeah, yeah.

A

I'm gonna send you an email and that's what I'll do is I'll get to that like right now after this meeting, I'll send you that out and then I'm gonna work on putting all the library files onto the d3d library page, so everyone has access and in the meantime, if anyone has any questions, feel free to ask I mean the way I'd, like I mean just just as a refresher on how the work log works, publish early and often please, the idea is like don't save like oh I'm gonna wait till Monday till I'm gonna publish my results, work well for one.

A

If that happens, then, like say I'm reviewing that I can't handle all of it and money, it's better. If you just keep posting little bits up one at a time, so that the progress and discussion is continuous. It's not like all of a sudden. You dump this lump of work on my lap or on whoever's reviewing it or whoever is the collaborator.

A

Think of it as a constant, ongoing discussion back and forth, where we're shooting comments and emails discussions back and forth, because there's a lot of complexity to this process. You can't just answer it all at once. So it's better as soon as you have a question. Email use, the the development network use the email, I mean email is right. Now, the most most favorable I preferred I mean email is very easy.

A

I prefer that you communicate like back and forth on an email as opposed to all just one time upload, because the theory here is publish early and often publish early and often don't be afraid to publish, incomplete work. Everything is incomplete.

A

Everyone's life, all the projects in the world are incomplete, don't be afraid to publish so that something that is visibly incomplete. You know that's the culture of open source. You got to publish early and often so people can build upon it. Don't be shy about it. It kind of takes it kind of takes a lot of self-esteem to do that, because you can't, you really have to be confident that you know you're gonna get feedback. If you publish it, it goes out and it's open to feedback and and people spamming it or whatever.

A

It takes self-esteem, actually a high self esteem for people to publish early and often because you just have to say simply to yourself it's okay, it's fine that it is fine, it's don't be afraid to publish that's the culture of open source, so I think with that said, that's about all for now and whoever is the new people welcome to all you.

A

New people you'll get a welcome email, including the free cat badge which we are preparing for you, so tell your friends about it, and otherwise, if there's no more questions, we can finish up right here. Everyone good hear.

D

A

Yeah I can hear you, okay,.

D

I guess I have questions about general 3d, printer yeah.

C

D

Files are there I'm, not real, familiar with the whole 3d printer yeah.

A

D

Been going on with that in detail, it's a big project, so I've been keeping an eye on it, but I want to keep doing the free CAD so that you.

A

D

Is fine with the I guess I need to look over the week emo I was looking at you.

A

D

It earlier exploded part animations pay with YouTube videos there so I'm guessing there are already free cat files broken down of these different parts and accesses. Or do we need to go to like to the central file and good.

A

D

We separating everything out and then making animations yeah.

A

No, there are separate files already, so that's the whole point. So if you look into the chat box, those are the relevant pages. You want to look at it's the d 3d log yeah. That gets you all the past meetings except last week's d3 D is the overall project page d3d integration is that page, which shows the actual breakdown of the machine. You can download all the individual modules and as far as the parts, the individual parts that would be d3d, part library.

A

So that's the part. Librarian I showed okay.

D

I think most of those pages open, let's see what else. Oh I still can't seem to get all right. I think I had access to that Google Doc, where they changed, and it's no now it's requesting whoa permissions again.

A

Yeah I see that so I'm gonna go yeah. What happened there so I'm gonna make that public to the web. Anyone can edit save. Oh okay, good point. Thank you somehow, I locked it up, maybe Google hacked it hacked us. Okay, it's all! It should be open right now. You can check that so good points, any other questions and welcome a good to have you on board and we've been working on a CB press and we're gonna definitely get back to that.

A

We're producing at least two two CB presses in in August of this year: more power cubes and a tractor and excavator and sawmill. So we've got we're gonna be very busy and in August. So that's why we want to master our free CAD and get the team growing. So we can really crank out product one after another. That.

D

Sounds good okay,.

A

All right, well, everybody! Thank you. So much if there's no more questions we'll touch. The next meeting is every Monday at 11 a.m. if you have schedule conflicts. Please. Let me know if another time besides 11:00 a.m. works now 11:00 a.m. is good, because the people in Europe can actually join us like Jose or Cedric, so 11:00 a.m. is good for Europeans and eventually, of course, we have more of these team meetings in different time zones. But for now this is the 11:00 a.m. Central standard time in the united states.

A

Yeah, that's about it!

A

So tell your friends and and we'll see you next week. Please email me with any updates or any questions. Don't be shy about that and continue the discussion and and start your log if you haven't and publish early and often so with that I'll get going thanks. A lot we'll see you again next week, and this is recorded so I'll put this up on YouTube as soon as I get this processed.

A
