A

Okay, recording started welcome everybody to the fifth of July right after the fourth of July meeting OSE development team, we're going to dive right in there's a lot of progress to cover, so what I'll do is as normal go through the agenda.

A

Please look at the working document and here is okay, so we're moving right along the development numbers here actually. Interestingly, last week we had a peek. So if we look at the actually reached a little micro peak in terms of development team hours, so we always track our number of people who are contributing actually logging in the work logs and a total number of hours divided by ten. So last week we actually had about a hundred sixty development hours.

A

I was a little over that essentially four full-time equivalent, that's great little micro peak, but we're still kind of at a plateau. Here, as we refine our methods, there's a big recruiting spree with a lot of people from Saudi Arabia that are actually going to join a team. So so there's that in progress should have a spike in developer population. As we start another team, the tractor team- actually we're going to get into that.

A

But, of course, the goal here is the 160 hours is essentially four full-time equivalent well, but at the full glory of the project we'd like to build up to about a hundred times, then so four hundred full-time developers by comparison Linux has four thousand full-time developers or contributors who are supporting the Linux kernel development project. So that's the kind of scale we're talking about and right now we're our very baby stages of where we are with open source ecology.

A

So this is uh but definitely on a path, and we want to see this this growing here. So let's talk first about progress of what's happened over the last week right here on the home base. Here we did a lot of work. We have Shane over lawyer from Michigan Tech University visit us for two weeks and we built a CNC circuit mill, which you see here. We were working on the main. The main project that we were actually working on is a power open-source power meter for the seed eco-home.

A

What you see here is the second story of the CD Cajon we're currently working on it. There's the power panel running from the photovoltaics and we've got all these different nodes. Like you see here, connecting to measure all the different power points from what are we getting from the batter from the photovoltaics?

A

How much is passed through the charge controller through the batteries through AC load, the DC loads? It's a hundred percent off grid system. We are not tied to the grid there, so we want to know exactly what we what we are using, and here we have sample measuring nodes here. It's a logging system, so an Arduino logging system that measures power. What we did here was we actually took our nuts, the big 1 inch, nuts, the same as we use in tracked in the tractor. We use them as a current transformer.

A

We wrapped a bunch of wire around that. So if you slip a wire into that nut, you're going to be measuring the current the AC current, because there's a electric field and get set up and a coil is pick it up to to get a voltage. So you can actually be measuring current with this, so these are. This is the open source board that was milled partly on Shane's mill, and here we've got work on a circuit mill here, so to return to that, it's actually quite exciting.

A

So the first run like look at this right here. Those are half a millimeter wide that little distance in between the two lines is one half millimeter, that's pretty good for a first try. What we did here was use the D 3 D CNC circuit mill with a spindle, so the same construction as the 3d printer, so showing that we can use use the universal access for different purposes. So we have a board and a spindle.

A

That's milling with this tiny drill bit or mill bit, and we put the XY gantry pretty low, so we have the optimal distance. So it's really stupid. The structure here is: quite nice. There's two two y axes to X axes and two z axes very, very stiff like when you try to move the bottom here, it's nice and tight. So we can get this kind of work, but it's try one and where we're moving forward on it here. What you should you see here is we're actually probing the surface.

A

So when you're mailing, you you're milling only 0.1 millimeter deep, that is tiny. So to get that you have to get the board perfectly level with that. How you do that is by probing the surface of your little Scentsy little circuit board, and you probe it by making an electrical connection between Sochi.

A

You see here are two leads: one is to the milled board itself and one to the actual bit the milling bit so that upon hitting the surfaces, you're, probing you're, probing the bed at multiple points to get a height map and the way you detect that it touched is when electrical contact is made. So hence those two leads there. That's what we did so check this out.

A

So this is a initial try with broken bits, so it turned out the brick bit was broken, so we got that, then we it's very easy to break this little bit. So so we did this and then we we got this result here and then went even better on try to, and that was done by lowering the gantry meaning, instead of basically making the distance from the bit to where it's held on the XY axis, the smallest.

A

So what we did was we lowered the XY gantry so that we're milling with as much stiffness as possible. If you, you know what I mean here, so that's pretty good and we're refining. So that's that's the stage we're refining right now. So let's take a look at progress on a 13-inch d, 3d 3d printer itself, so I've been printing a lot of parts these days, there's a bunch of Tyla time lapses. If you go into the View mode present mode, you can see this video some parts being built, so next is building more.

A

So this is in production, so I'm made nine more frames. These are 13 inch cluster for 3d printing. So here's some steps in the process, all the 3d printed parts, putting the bearings putting a bunch of screws together and so forth. So that's moving along the ideas. Our goal for the next workshop is to is to build 24 printers. That means a lot of printing of parts. It takes about a full day to print one set of parts like 24 hours. So it's really like one or two days so thinking about 24 printers.

A

We would need 24 24 days of printing non-stop with a single printer, or you have multiple printers. You divide that accordingly, so if we have our, what we're going to have is 10 printers so take only a few days to print all the parts, so that would be really good. Okay, next next product, so we're working on a print cluster here. So we came up so this is Christian or new developer and working on on a an architecture for how you take a little little microcontroller like a like a Raspberry Pi.

A

So instead of using a computer, a computer, each to run a 3d printer which takes energy energy Computers, take a lot of energy, just use a small Raspberry, Pi, microcontroller or micro computer, and connect multiple connect, the USB hub with multiple wireless controls. These are you UART.

A

These are these little wireless modules working through the UART, which is a serial thingy and then the then a 3d printer itself has its Arduino with the Ramseys board, with a receiver and an SD card so that you can basically lob over. You can throw over the file using Wireless just like remote control, Wireless style and one single microcontroller microcomputer Raspberry Pi is controlling the whole cluster, so for us it would be about 10 of the 3d printers using a small Raspberry, Pi, so very energy-efficient.

A

So this is the basic geology or architecture that we came up came up with, starting with a computer, with free CAD with a router with Internet and then throwing that onto the Raspberry Pi and then controlling a bunch of 3d printers with that, so that's in progress, Christian is working on. I should make an instructional she's doing really well installing the operating. How do you install first an operating system on a Raspberry Pi, because you actually don't have to do that? So there's an instruction on christian log.

A

We can take a look at that continuing so yeah, more more about Christians working on, maybe I'll ask ask you to pipe in a little more okay. Next next item. So as far as the micro house, CD eco home rather see Nika home goes, we've started the full CAD in free CAD as far as like all the plumbing. This is actually plumbing for the sisters, the water cisterns. The point here is altogether we've been doing a lot of these diagrams with just cut out you just basically two-dimensional diagrams.

A

Where you cut out like visual bill of material style, you cut out all the parts and pieces together, but now, of course, which one would you rather have I, don't have it for reference here, but this 3d picture is basically a much more realistic representation idea. Here. Is all these parts were pulled down from mcmaster-carr?

A

So that's that's a really efficient way to go, and then you can work with a realistic design where a lot of times what you'll see is if you're working in 2d, you can't really picture how the parts go together when you're doing three-dimensional design. So this actually found this to be just about as fast as doing the two-dimensional renderings, while using the real actual parts to download these are like one-inch, PVC fittings and so forth. There are actual real parts that we are using in the system.

A

So that's that's an example of using CAD for the house design parts utilities, specifically what we'll do is as soon as we have enough people with, we can put together a team of people to work on a full utilites cat. We've got most of the cat just about all the cat for the house and sweet home 3d, but the utilities are a major major.

A

It's like they're, taking much longer than we thought, they're experimental, but a very interesting stuff, but full cat needs to happen so that we can then have virtual up to virtual reality, walkthroughs and then at the most elite level of what we can do with 3d. Cad like this is make augmented reality instructionals, so something we're actually wearing glasses, which superimpose information on your field of view. So when you sew actually shows you how you put the parts together by providing you with additional information that you see through glasses, so this is augmented reality.

A

Stuff I mean that's something we can aspire to later on, as we get the design more complete, but that kind of technology is available and there's definitely some things in the open source that are available for augmented reality. So we can do that. Okay, so that's a house design next filament maker, so we've got these are so we're populating the part library of the filament maker with actual 3d designs for all the parts so like, for example, here electronics we've got simple renderings that we are actually doing in the freaking.

A

I haven't actually checked how the files look here. We've got that a plenty another example is I'm, seeing the thermal components. So we broke down the on. That's the alignment. Filament extruder part library broke down into the we broke down the work into many modules, so thermal components, spoiler, spoiler school mechanism, etc, I'm, seeing they're getting populated. So that's really good. The next step would be to finish all the different components and and then assemble it into final CAD files.

A

So let's see what else we've got here, so this is the filament maker that the currents current step here is the full cab that we're working on website in progress. Jose, if you want to let's see, are you here now. Jose is not here, but we've got a prototype of the website, so tomorrow I'm going to be meeting with with Michael who's working on a back-end, revamping our back-end and installing the gypsy video bridge.

A

So we can actually go for the open source like hangouts, but with unlimited viewers, where it's working on installing that and revamping our whole back-end in the process here. So we can look at installing the website tomorrow.

A

So the idea here is, you can once again go into the View mode present and you can look at this video. He did a video explaining what he's got so far on a website, so.

A

So, let's get to the question questions in a little bit, but let's just go through quickly on the the progress on the main critical path for the team. So if you take click on the link on page number two here, you can actually be taken to this real diagram which is actually open for editing. So we can contribute to that. But what's happening here.

A

The basic idea is the the green line represents the current time, but you see we're working on a bunch of little project and we're going to add the CB press. We're actually gonna have to start working on that because there's two main events happening at the under the workshops: column there or row the I want to see. If we can do the three printer workshop, the 12th of August so yeah pushing this way a way later than we think.

A

But twelfth looks realistic because we got to get done the print cluster going to print all the parts. For that workshop, we're going to need a lot of parts and then the 25th of August is the CD press power cube workshop, where we build a power cube and brick press for a client which is the University of Utah. Actually, they have a design-build architecture section where they're building houses for underprivileged people, like some of the Native, American reservations and stuff they've, had projects but we're providing a CB press for them.

A

They're coming over a few of their students to actually build the press, we're hosting a whole workshop around that that's a big time on the 25th, where we're with the CNC torch table, we'll be cutting all the parts. So this is going to be one of the firsts we're outside of some initial part. Cutting for tractors in the 2012 production run.

A

We've never used a CNC torch table sense because we've never got it to the level of refinement and now we're working on an automatic, high controller and height control to make it fully operational for part cutting for their CNC using CNC for the brick press and power cube, and if that actually is in good shape enough. We can actually consider cutting some of the frames for d3d the 3d printer I'm, not banking, on that, but we are definitely cutting the parts for the brick press for using our through our CNC torch table.

A

So, just going through all of these here how this fits together, the CNC circuit mill is the current progress is to refine those circuit milling capacity. So we can get very reputable meaning, like 80% success rate on the very fine circuit boards, that our point that have point five millimeter traces. So that's like really tight. It's it's not this! Not this rough one millimeter or a couple of millimeter and milling. This is very, very fine traces, so you can actually do things like even make your own arduino, x' and parts etc.

A

So very interesting idea we talked about is when we do the 3d printer or in the future. Actually CNC circuit mill workshops.

A

So sometime in the future, we're going to have I, don't know when but I'm going to put a workshop there once again, one day build where you learn how to build a CNC circuit mill, but also how about using one of the built CNC circuit mills to mill its own electronics, maybe the power supply or its controller, so we're looking at very exciting workshops with that, but we're refining it to get full capacity on that, and so so let me just state the importance of the CNC circuit mill like why it's quite exciting.

A

Nobody on this planet has actually done a circuit mill with belts that gets. This type of resolution is 0.5 millimeter, trace width. This is a first and by doing a very solid frame and is doubled up axis work. It looks like we're going to be really able to achieve that using gt2, six millimeter wide belts and pulleys, so using a very, very brute force, kind of a drive system. Typically, people use use a lead, screws or threaded threaded drive systems to get this kind of precision.

A

But the facts are: if you want to look at some numbers, the step size on the stepper motor, if you do, the math you're actually getting point zero one millimeter, so one hundredth of a millimeter step size on the actual. What you see here in this picture, the actual step size of what the stepper motor can resolve is 10. Microns. That's point, oh one of a millimeter. So that means, if the machine is tight of the structure is tight of the belts are tight.

A

You can get ten micron resolution, which is perfectly fine for milling, very precise circuits like that. So the theory says it's possible and we're pursue doing that. Okay back to so that the relevance why the CNC! This is really cool, because you can then have a very low-cost CNC circuit mill, high price, very, very high precision, the best there is, and you can do it with belts, very cool, okay print cluster. That's ongoing I'm going to be working on this week, really getting all those 10 up and running.

A

So we can do the torch table, part, printing and then part printing in production or 3d. Printer workshop, so the torch table this column. Here the build is coming up. I mean I, got to start data next week here, because we're going to start have to start some parts. In the meantime, Oliver was has been doing the electronics design and the prototype, including the manual high control.

A

So that's also I'm already building that next week this this week, I'm going to still have to focus on finishing the 3d printer cluster and testing out the code and are doing the Raspberry Pi doing that as far as the print cluster, which which Christiaan is, is doing a great job on in terms of the print cluster software and protocol process for that software and hardware for that build coming up next week. At that point, I'll install the height controller.

A

If we have the automatic controller that'll be great, if not we'll use the manual controller and then it's part cutting that's like in a couple of weeks, so we're really rolling on that part cutting towards the end of July two or three weeks from now we got a roll, so the workshops, as far as getting an announcement, the announcement for the three printer that has to go up by next week to give people a full month of lead time to sign up for the workshop and then CB press has to be announced the week after.

A

So we give people a month a good month of lead time a month and a week here, so they'll be good. While time is flying here, boy, an untracked, er team, as we get the Saudi Arabian contributors, which were interviewing right now, a number of them we're going to start rolling with that.

A

Probably next weekend we're going to rope in a manual who's interested on one of our early deaths, the Greenbelt developer.

A

Who is going to join back on that team since he's very interested in that? But idea there is one like in a recruiting process. What's happened is the one of the developers who applied said: hey I've got this hackerspace I'm working on a makers initiative for the North, Africa Mideast region and he's got a lot of collaborators there. So that looks like a really promising collaboration where we're looking at a very big 3d printer build in December, where we build a hundred 3d printers in a single day.

A

That's going to be a major major undertaking, so so those are the same guys. Ok, maybe then I can open up the floor to two for other people to fill me in on any things that we miss anything from people that are on the call to fill in the gaps of where we are in a status, maybe start with Oliver, maybe update us, please, where you are. If I miss anything?

A

A

Would you mind speaking a little louder, your your little soft here or maybe yeah? Okay, there yep yep this bed up like this. Well, definitely, it might have been my sound okay. Yes, definitely better! Please go ahead. Okay,.

B

Yeah I've made some three PCBs and then.

A

B

See from vias that I'm pretty sure that the circuits are running correctly, I have was just short before finished with soldiering, but um I've made a little test. Rick and I.

A

B

That I utilized somewhere, which I found, which was from the work from Aidan Williamson, which was so far as I, can see in the lab. I worked on this it's from 2014 and yeah I was able to find his last undercoat and use that as a firm lab, and it seems to work how far or I could say from my testing that I think it's basically working awesome.

C

B

Was able, with with that test rig to do some some measurements over a distance of 5, centimeters and I was able to see continued use the variations in the signal? Oh you can you can see if you run little bit deeper, you can see the test rig. Okay,.

A

So that tell us about that: how? How did that work cause more? Yes,.

B

There, it is, you see, it's a really really simple structure: I've, just taken a plate of copper and as a central probe, I have just taken the probe of my oscilloscope, and so it's quite primitive. So, but with this, I could, as I said, receive small variations in the signal. But it wasn't a very low range like the normal range is about eight Pico heart, and here we are more in the range of 10 to far meaning back to a thousands smaller.

B

But the thing is here: I mentioned the probe from the oscilloscope, which has a very sharp relative yeah.

A

B

Normal you one should have this ring, so what our universe found in the literature from Eden and so on was then probably a bigger probe or ring crow. You.

D

B

Give maybe stronger signal yeah.

D

B

Signal is also quite quite noisy and and sensitive against any ENS influences and thing, but this was really just the first half yeah.

A

B

If my thoughts are working correctly, if I soldered every clean, correctly and I, think that is the case so that in principle, I can send you one of these boards. Well.

A

B

Because everything, what happens from here now will probably take place in the soft and the film where and so on which which we can update by internet. Well,.

C

B

C

B

Challenge from here now is to have to make a better signal and then to implement it with the other motive, are handling stuff and yeah.

B

The next thing I'm going to do is try to building a sand or with ring and causes using maybe the Trotter cable, this cable. What I have here on the probe is about 1 meter, maybe getting better. If we go to 20 or 30 centimeters and yeah I hope the ring will bring the clearer signals and at the moment the signal-to-noise ratio is a little bit cause I, think and but there's some hope. I've seen their worth in the Year 2015 a dialogue between a maiden and the guy named Clement.

B

It which also tried to reduce the setup and was probably able to achieve even better results. I have put a link on the YouTube video what he made it is in my lock page the discussion page there. There is a link to that video and there you can see relative good resolution in a range of 120 meter. What he is doing so I think it might be possible in principle, but there will be maybe a fight, a challenge to get better shielding grounding whatever stuff is helpful to get to single Kyra I.

B

Think software so far were so good. So far our and now comes ooh, yeah yeah. This is it the video no.

A

So that shows the capacitive measurement voltage. Yes,.

C

B

And he measured about I, think 10 millimeters and in variation steps of 0.1 millimeters so that you have.

A

B

General that could be achievable at he burger wow.

A

Yeah, that is that's pretty good. I haven't seen this thing. This is good. This went out into the wild and some people picked up on it to actually take some real measurements. Excellent for finding that a.

B

Big applause also to Aidan, we've documented as well as also said willing. He had put all this email discussion with that guy into a PDF file and have linked it to the lock I. Did some detective fish refers to follow all the traces and followed all the things, but yes, we're done yeah so far. It saves me a lot of work to find this and to be able to use somewhere and so on. So it's a typical case of you know.

B

Maybe the saying we are standing on the shoulder of total of giants is a good example. Excellent. After father ADA.

A

You are a giant and I'm going to send you this video okay. This is excellent. That's awesome how we're building a good example of how, because it's documented we're actually able to take the work that was done a couple of years ago and completely take off where we left off at that time, which is good. Very nice yeah mum.

B

I'm, a at one point more that is from about the sampling theoretically, would be maybe able to do some softer filtering stuff like simple Everett ring together. Better signal, but point is that the the Sanwa sampling is quite slow, I would guess or estimate, maybe in the range of 500 milliseconds per Center. That means you have not very much time to get a whole buncha people are doing an average about an equal, thousands or something, but maybe nothing possible in the range of of 10 or something I, don't know yet. I have no real imagination.

B

How fast the torch is moving forward. You said it more slowly. Moving and I mean on the other end. One can can maybe wait at one point until the sampling this time, however, but I'm going to play with them and try to maybe do an average about more samples and from those also get a better signal, but my main hope is on the on the ring sample, and that will be my next step and as I mentioned, if you want I can tell you one of the board's over them. You can also do something. Excellent.

A

Excellent yeah, the speed that we're talking about is about one centimeter per second, which is in English, that's 20, inches per minute for half-inch steel. That's a probably about one centimeter about one centimeter per second right, because that's about 50 centimeters per minute, so about a centimeter per second yeah.

A

How do you know? Let me ask you this question: when you say the you're measuring picofarads, how do you get that value so there's some kind of scaling that you're doing already yeah? How are you doing that.

B

I mounted the thing the probe on the linear drive and then moved it. I marked five marks in a distance of one centimeter, so five centimeters neat and then I move. It forward moved it forward, one centimeter and then the next centimeter and so on, and meanwhile letting lock the the sample data on the on the serial monitor of the arduino ide and at the first place, I get a value which is about eight point.

B

One nine three picofarads interesting is that the same value, which Adan also reported that he gets at one point and first it seemed to be this value. But if you take a closer look and then you feel suis places behind the the Point C, some are more or less regularly the numbers which you can relate to. If you doing the moving forward, meaning getting closer to the plate to the surface, then the values are arising.

B

Constantly, it's not probably not a real senior mini are arriving. It's more like more. Like a parable like we have seen in the video of Clement V Commission assistance gets closer than to 2 or 2 1 1. Our saturation point off, if you go yeah.

A

B

A

How you can be scaling to correlate the two picofarads, so you've got were like I.

B

Then, when I saw that let this happen, I think we subtracted a value of eight point, one nine three of it and then multiplied it by a hundred thousands and then I get a more more economic scaling on my screen, which is to 2 part number like 22, 23, 24 and so on, and when I move in total, the distant of 5 centimeters in the beginning, I'm in the range of value of 20.

B

What I call pentalpha, let's say, 20 pentalpha and if I closed to the to the surface than hire 40 so I have arranged off of 20 up from 20 up to 40 means distance of 20 cent too far in which I as here of the 5 centimeter distance, and it seems that in the nearer range it's getting better or Harbor and in the more distant range, its the bits. It's more noisy or an unclear on like that.

B

But I think this is all not why some meaningful, because we still have not the right cell were set up. So yes, but it was enough for me to see, there's happening something regularly, which let me assume that at least I've soldered to work correctly and also over designed them so far at length of its design correctly.

A

Now I think this is a yeah I think that's really good progress that you actually seeing that with like the oscilloscope probe, which which really has no capacitance, there's very small surface area. I. Think that you have succeeded seeing something with that. That's that's a miracle right there, that's that's great! So we can continue. That's true.

B

As I remember, one point is a report of my anchor stuff where they also did the jump from a smaller diameter of the sampler to bigger diameter, and that seemed also has to had some made. Some resulted in some good progress. No.

C

B

Not mouth but I just wanted to I was ready with soldiering, wanted to see something, and here.

A

B

And I mean when I built the real pro a new sensor, then a smaller second advantage that I have my probe from our oscilloscope back and when I can do. Some memories was my also ii yeah.

A

B

Yeah and by the way, one other things I did my my test run two times. First, I knew the carriage with probe by hand and then secondly, I let the carriage move by the manual height torch controller, which we made last time and when the electronics there is no power, supply and stuff work near it, then it was getting a little bit more noisier than when I did it from from hand. So I guess that the general challenge will be to fight the noise to make better grounding, shielding and stuff like that. Yeah.

A

B

Even there I I could could the continuously arriving or decreasing of absolute also value so is also open. Yeah.

A

No, that's that is great progress, so yeah excellent work, so we'll continue doing that and in the meantime, I can definitely implement your next week. So next week, I'm hoping to implement your manual torch controller solution as well. So that's good and we can definitely get some initial cuts on the CNC torch table. So moving right along really.

B

Cool I mean we are double ways on the safe side, I mean, even if the send caps and ring circuits are.

A

B

Be working what you.

A

B

Seem to be the case, but you can. If then at least you can use my board as a hand, control thing of it. Of course, implemented in this enter as file I can see. The Arduino Nano you've also be a good choice in this setup. So it's useful anyway. Yeah.

A

Because the same board can be made to do like what you design the the other system I mean. Can this be adapted readily to the manual height control? You see.

B

Any I mean yeah. If my BOTS reach you earlier, then you are ready to rebuild the thing with Arduino mega of inputs and stats immediately use this yeah.

A

Okay, excellent work; okay, very, very good, so we'll continue we'll continue on to the next topic here and just keep going thanks a lot. Mm-Hmm next is: let's move to the filament maker work as far as what all has been has happened there who wants to report in on that I haven't studied in detail exactly what the status is Dixon. Do you want to pipe in on what what all has transpired there I.

D

Can pipe in runnin for challenges we kind of uh screaming silence and detailed user. But if you look at the part library, you can see a ton top of this. It's getting populated with pictures and let me take the links that are.

D

Getting populated, there's free CAD files for some of the I guess non printed parts which is good because those are some one for you. Oh ones will probably pay for more work, I, think and yeah. So that's the population happening and I added a slide to the end of the step team meeting, where I just have a small amount of work that was able to I just wanted to check that I uploaded one free CAD file for the extruder barrel that you can see right there that four inch or half inch, oh and.

D

D

I upload the first, the unsimplified there are facing the link to that.

A

D

I upload first, the I'm simplified versions that I got directly from either rational or mcmaster-carr. I can't remember in.

A

D

And that's 929 kilobytes and then I upload, another version which is now the current versions that imply versions where there's no threads or anything. It's there's a smaller space for the threads, the visualize, where they're at but that's down to pod kilobyte I mean.

A

You wanna make.

D

Sure for intending when you described in the parts of application, video on using dis, versioning things so that we can have with the elements, but because that's what you're hoping to have for all be part right. Exactly.

A

So that's that's right! On going from 900 to 5, that's a definite, definite major reduction and just to see how it works. I mean that's perfectly fine, yeah that that represents that's 5 K and it represents where the threads are. So that's exactly what we're looking for and when you do, the saving like when you view it go to perspective view. So it looks kind of more in perspective like when you do screenshots and so forth, but that's exactly exactly what we need so that that connect Wilden.

D

A

D

We use that part of the reference for how to do that. I guess yeah.

A

Is that linked in slide, 16 or.

A

D

Then the one other thing I had in there is some the file names I have made had slashes in them, and OSC length doesn't seem to like that. I'm just wondering.

A

D

Resource has been made for file conventions in regards to at.

A

Sorry say the question again regarding Falcon vent convention for OSC Linux I was.

D

Trying to save some of the file as the way it has named them in the part for library and OC Linux I got unfortunate. Busted screenshot of the air, but I see when X is telling me no slashes and file names, which is obviously this one. Now it usually is. I was just wondering it. um I was wondering if there was a file name convention resource on the wiki, yet yeah.

A

Not know but I don't have it I think I think what you have, let's just keep going with it we'll get there I think we can handle this with just doing reasonable file names like LFX, with climate, film and extruder nipple, black iron, excellent yeah.

A

So, let's see what about Roberta also says: what about CAD files with same object but with different position: how to put them in the library like different positions like different viewpoints, different modifications, they could go simply up, I would say just upload them over an existing file. So if you show something interesting like even if it's recoloring parts in a different way or adding an exploded, part animation or whatever anything that you change, you can simply upload as a new version and just make the notes that that's what's happening in that specific version.

A

So that's does that answer the question Roberto.

A

Hopefully, hopefully that answers it and continuing on Roberto log here, so we've got yeah, so he piped in this this this one right here, but this is this- is what we're trying to do here so basically label all the parts for that particular module so like here, for example, we have I, see we didn't really say who has what outside of the working document. So let's go back to the working document.

A

And look at the allocation of the different tasks.

A

Okay, so on alignment, film and extruder.

A

Page we have the working back from last last week. Do we have that there? It should be there what we were allocating people to. So, let's just open up that document here.

A

Yeah, so here is what we have so, for example, Roberto here big box, enclosure plus hopper. So then we have the resulting product right here. That's that's excellent work right there and on his log. So that's what we wanted to have from everyone just to keep good track of what all the parts are covered already like it. These are already linked. What I'm expecting here? Look at that final assembly with sketches without sketches. Let's go to this one. Ok, so Roberto has done some good work here.

A

So let's just take a look at a download of that.

A

So so far, what we're seeing is is the complete workflow that we discussed last week, which is label all the parts linked to the files, then for each one of these I would be expecting that to go to the wiki and to the actual free CAD file, as it does so.

A

This diagram here shows me that all these parts are do have links and therefore this looks like it's very complete and then you look at the final assembly here of 20 parts and it is there so after downloading that I'm going to just double click on that. Let's look at what the final product looks like in free CAD.

A

So that's great work and therefore the other people who are working on on the same on the clothes some right here so Abe will Cassie IO, Israel and Dixon yep.

A

The idea would be to do what Roberto has done on that. Let me see this is opening up here. ah Look at that! So that's Roberto's product and that's looking very sweet, very nice.

A

So, yes, you can see all the different pieces I'm going to hide and unhide them, but basically there should be yep stripping. All the parts corner panel corner panel, extruder case front panel, hopper, knob, side panel and bracket and bottom panel wow, that's great!

A

So that's exactly what we're looking for and then once we have this I mean this is like pretty much ready to be printed. I guess in full, so this is pretty good. This gives me an idea like I could take this download all the files and start printing.

A

Now the one thing for printing so say: let's go back to the document right here so also, if I go to Roberto's log I would want to see okay, excellent, so there's all the all the files for the free CAD and the next step would be also just export the individual files and just say: okay, the same thing, but that STL and the so then then I can go down this list download the 20 SDL's and hit print now the numbers of them like in this diagram. We should have a corner panel.

A

I think this is that you print each one of them just once, because they're breaking broken down looks like what we have here is they're broken down to the individual part such that the printing is just simply one one print of each, and that is good yeah and then, on this specific case, the next would be some of the heater element, but that's another module. Isn't that so, if we go to so you have a thermal components like this: the extruder barrel, auger and flange.

A

Once that is done, we can append that like here we have that box blocking out the extruder barrel and so forth. So that is pretty good light. And if we have that now the auger, let's see the auger yeah. So that's all in Dixon's work, the auger plus flange extruder barrel and a way to mount the auger to the to the drive motor I, guess: spooler, I guess in this system.

A

What I'm seeing is that we kind of missed the the motor drive part, which I think I'm going to just add that I'm going to add that to Dixon's since you're pretty much.

A

ah So in this working document, what you see this is good working by Roberto, but yeah that this is in the working document itself and just keeps skipping up every time, I press it yeah.

D

A

We're supposed to paste in the finished finished assemblies into the document, but that's that's really good, so what I can do is literally I mean if I get it the first chance to start printing I can start printing these all these elements and what I meant to say is that uh-huh extruder electronic module visual index so this here, what I'm seeing is yet part of the this is I. Think where is that aid was that electronics by Abe?

A

That's correct, so he's part way done through the visual diagram, with all the parts linked to the files so for Roberto he's the farthest along and the next step on this here would be just to export and link to all the STL files. As soon as that's done, I mean I can I think I can start printing this within a week or so once I give the cluster. So the main goal for me is get all the cluster going this week, so I can print things in math, so we've got competing devices to be printed.

A

There's the torch table, there's more printer parts and there is now the filament maker. So, as you see that the 3d printer is a very, very important tool, in fact, we'll be printing, some of the the drawer rail guides for the brick press, also using the 3d printer, so good work, excellent, excellent.

A

Now do we cover everybody, that's the progress of everybody. That's in the meeting right now or anyone have any other.

A

Maybe about the cluster? Yes, sir Christian, why don't you fill us in where we are on that? That's an exciting project that has major progress and please go ahead and fill us in the word exactly. You are.

A

We cannot hear you see if you can maybe unmute yourself or restart, restarting typically works or otherwise.

A

We need your voice and a quick reminder. In the meantime, everybody please slot your timesheet. If you have done work here, we've logged seven people this week. I think there should be a couple more.

A

Christian yeah, you see if you can draw there, you go. Please go ahead, we can hear you Wow.

E

Okay, um absolute free prints, Leicester and Britain and I'll research about how how we get to this.

E

How much done open software by now and we've come to the conclusion that for for hosting does different printers, so we will use octave print. This is open source already, and it's been around for a few years now it's pretty pretty refined. It is also like those mentioned before it has the option to load the software up to the softest gcode after the SD card, so there's nothing new or special that we have to do for them.

E

So we we took. This is the basis, however, the biggest problem about that is that it's only designed for one printer at a time. So it's not really a class turret, simply a management system for single printer. So.

A

E

Working on was the of the management how to expand this for most printers, and this is possible. It has been done, however, only on a small scale, no more than two with documentation, as far as I could see so I have to ride on scripts that automate the process of pulling the the printers together and that's exactly what I did.

E

I can't demonstrate this right here, because form I don't have a 3d printer and for the other, this only makes sense if there are multiple 3d printers, of course, because otherwise this kind of software won't making sense right.

E

That's that's the reason why we need to set up this thing on your PI, as here.

A

E

Mm-Hmm, so I can use this scanner RF, written and patent. This thing automatically detects all of connected 3d printers that sense them g-code, that analyzing that sense basic information and one on five for mullen, and it's just sending back the printers name and somewhere and stuff like that, and the name is then written down and kind of organized an internal file, a little file and the setup is then corrected accordingly to the amount of 3d printers and also according to the mains of 3d printers.

E

So they all have individual names given to them on the firmware. So we can take keep you apart and give them two names like for four different types of filament or for several extruders and stuff like that. So we can speak them um yeah!

E

That's what I was working on that that's one thing, and another thing is how just shortly share my screen for that.

E

You know I've written additionally a little web server, because each instance that immense is a 3d printer, will then result in in an own in an own website in its way as black, but not not an online website, but an HTTP things yeah, and this is a problem because then we have let's say 10 or 20 websites that are apart from each other and with different URLs, and that will be just pain, so I work on a unifying website that pulls them all together.

E

And that looks a bit like this at the moment. Can you see it yeah.

F

E

So up just it's pretty basic. Actually, it's a little food shuttle looks pretty nice. We've got here a few settings, so we can get four new devices here and we stop the machine. I've got a big copy right here, we'll fill in what's what's necessary, we can put in here widgets or stuff we think is necessary for for the rad lab configuration and stuff, and one button is here. The first button is a 3d printer managing the cluster and it only dummies they will be created dynamically.

E

According to the 3d printers I had known, I have just observed symptoms and when I click on them, they dynamically load. So, oh, no, no here is the octoprint and we can work upload to the system and then to the SD card. We have temperature here and, of course this will take the default settings for different printers.

E

We have to talk later on how this will exactly look like and when how we're switching between those it will automatically load the most current system- sauce not everything's loaded at once, because that would be a lot with huge load for the full Raspberry Pi. But each but each cap here we belowed it's only when clicked upon you.

B

E

This will optimize the efficiency and will make this much more scale. Blasting yeah.

A

Wow, very cool Tony out what language are you programming, this integration? This.

E

This is pipes last, so it's mainly tighten, but it yes, it's actually not that difficult. It looks so nice only hit because of because I was using bootstrap that that's all I've just copy pasted a bit of bootstrap that it just looks nice it actually pretty simple. It doesn't involve any JavaScript except automatically loading.

E

Of course this needs JavaScript, but this is only to make it even more efficient, so it's just too until abides or something like that, so it's as simple as it can be as it can be, so it can just do all these things on the Raspberry Pi, without any kind of lag and with scalability up to maximum.

A

Very nice, very nice, do you have looking at your log? Do you have any where's the source code? For that? Do you have that upon move yeah.

E

Yeah screen sharing so yeah upload the zip file I'll eat that, in my in my log and.

B

E

Are this on my on my passion to get this web server and stuff load loading after all of this, in a step-by-step process and I've created a wiki page on how to make out of the occupy image? That's the basic of the octoprint to make all of this the system I have right now I get additionally to that. There are all the all the flattened, scripts and stuff I braided. However, there are mainly untested, so they will be just there and they will be 1/4 updated and it's about 400 kilobytes.

E

So it's pretty simple. It's pretty basic! Actually like I said hTML is as simple as possible. The HTML sites themselves are only 2 to 5, kilobytes I. Think so.

A

E

To nothing young.

A

E

Enticing scripts don't take up much of space five or six kilobytes people are queuing up for scanner for 3d printers. That's basically all asking us just little management. Tiles III need four for expanding the keys for the default setup. Excellent.

A

Yeah and I see you have the link to the source code or no the instructions for take. Let's see some of these instructions, how to create point of imperfections.

E

Myself, those are nicest thing, go, go blank again and then set it up like like instructions and work. So it's as simple as possible until construction yeah. So then.

C

E

My current status and for further working I just need your. It comes from how exactly the pre difference should be managed and, of course, on testing it upon your printers or at least one printer, to look other sub 25. The speedy bruisers excellent.

A

And, let's see so, that's um I just downloaded your print cluster extract here. So if I take a look at your print cluster data, that is it yeah. So how do I take that and install that in my computer? So so.

E

Of course nothing for your computer, it's for your reply and instructionals operatin in there are pretty accurate about that. But.

A

E

Can describe it to the right now. In short, if you open this the file, you have an accurate screen sharing and also come from what you're doing, but if you unzip it there's a reason II and inside this readme there is everything you have to do this thing to get going. So it's pretty simple as that. If there are any further questions like I said, the wiki page is actually even more accurate. The reason is just the most simple, most simple steps, so.

A

You're staying playing the the readme of how to create the printer cluster image, so basically you're you're, creating an SD card right with the operating system for the Raspberry Pi. Is that correct.

E

Maybe maybe a penis formulated that, but it's particularly at I, will create the private cluster image with that at the moment, there is none, so I'll upload a modified version of the occupy through the to the side. However, as we want to be at Sanford as possible, I want also to document on how I've created this image.

E

So this is how the image is created, and this is nothing I, do on the image but I've just right up to its the SD card, hood up the pie and then I follow the instructions left here by a SSH like I, like a also set in there. Scroll down you'll see a what kind of of orders. How do you say edit? What kind of light out to the lines I put in to get the software? Exactly like this with me on.

A

E

A

Oh yeah right, so let me let me just clarify for everyone so how to write an image to the SD card and then how to create a printer cluster image. What's the difference between the two.

E

These, the the write to the SD card means I'm, taking a blank, hard drive or SD card investigate the it's kind of the HDD or SSD of the of the of the reserve is be SD card, and this has to have some kind of operating system. So the basic operating system we need on the on SD card is the occupy. So I put the SD card into my computer and I've written a little weekly page there as well. Writing the image to the SD card.

A

June 30th entry they're right here, yep, so how you do that exactly mm-hmm and.

E

How I put this on with all the limits and after this is written, I can just insert this hard drive or SD card into the Raspberry Pi right.

A

E

It in so it just opened up by default, and it will just yeah like I said it will good up and it will get into the network and there RSQ provided either an Ethernet, cable or you put in the credentials of your Wi-Fi. This is also described in the SIM card set up yeah, so it will be automatically be inside your router inside your network story, and you can then SSH to it. So this means a command line, command line, connection to your Raspberry Pi, and then you can do all kinds of things.

E

You can also do the subscreen there's, however, no quiso, it's no! It has no fancy desktop, it's just a wide wide blinking line, indium putting ours and so on, and the others you need to get the sip software I have is just left on the second wiki page. So the Paris thing is more general. You can set up any kind of operating system for the PI would first, you can actually set up all the Linux with those commands. Well, okay,.

A

Sorry, I wouldn't.

E

Advise in this D card I would advise in USB stick, but it works basically the same and the second one is actually making out of the specific occupy image. Our.

A

E

Image we will use for a black, especially for 3d printers like for me, laughter, yeah,.

A

Yeah one comment on the rap lab, so that's the replicating self-replicating open source, Fab Lab, that's a term! We used actually a long time where we haven't used that term of ret lab. But it's that's. That's for anyone, who's wondering what rep lab is it's another name for open-source microfactory open-source Fablab for everybody actually.

E

Use this term because I found this most often it seems to be the most universal term. You have for this yo app just use this, because I thought maybe this server I, don't think it will be kind of it will be overheated because of simply the two printers it manages, and so, especially at all its tributes. The the file to the SD cards and chips will be idle, so I thought. Maybe this is kind of viewable. Also my design of the of the main of this website.

E

We can add other, maintaining and managing functions, or maybe just widgets for for, measuring or or just converting files not like that yep. So this is kind of the main brain of the author of the Rev lab, maybe in future yeah I'm just waited to be adaptable in that way, right.

A

And as far as the print cluster data that zip, the thing you showed on your screen share, that's what actually goes on your laptop right, no.

E

Not not destined nothing, nothing on the laptop actually after you dude set up this. You download the zip file. You also unpack this onto your sd card, and you can do this actually also the command line. There's one for Margaret.

A

Called down again.

E

A

E

A file from websites which W get looking.

A

E

How this is use is pretty simple command and you can then get it directly from the wiki and then you can unzip it, and then you can just move the files that are inside this accordingly to the step-by-step tutorial as a veterinary output there, where to put a well how what pilots going where okay.

A

So so, just to get the architecture clear here, so we're going to use our laptop with our C Linux or Linux, and we're going to create the SD card that then is used to install the operating system on the Raspberry Pi. Once we have that we're going to communicate with the Raspberry Pi via the laptop and then have the Raspberry Pi we're going to put on this other printer cluster software onto the Raspberry Pi through the through our laptop. Is that correct? Thank you. Okay,.

E

We have figure in it too, to make it our special. Our special OS, however I'll at the end, I'll load up an image. That's already finished, so you only have to make a do step. One so jump has to put this into your laptop and set this up, and everything else will then be fine and already done so. This is just for the expert or those who, like the transparency, to do all themselves, yeah, it's more less for the on a logging, yep.

A

E

A

E

A

And as far as within our print cluster, here we were on the June 27th date. We've got the full build materials that I need to order and get on with that. Okay, I'm.

E

Gonna actually about the hopper side, so, like, like Marshall, said at the beginning, we're using this wireless communication between the difference between your upper principle printers it's kind of like a like a wire connection, at least from software side, as there's no differentiation, it's just taken to to rate your wave and then and then connected to each switch otherwise loop. This way and they're different channels, you can adapt. So every every 3d printer will be on its own channel.

E

You know and yeah, as you can see, on the under on the block materials will have one one USB port for call for everything for every 3d printer than one one USB two to tutorial and then put in the wireless on on the side of the thoroughfare PI one last receiver on the side of the printer and, of course, an SD card on the side of the printer and that's actually malas. It yeah.

A

So I'm, looking at the bill of materials and it's about $85 that would be 4. That's a 4 channel hub so to control for printers.

E

Right then, that's about it's right. It's.

A

About I love that so it's real! No, that's good! What.

E

I wanted to say: buddy is be happy with the are cheaper options out there, but I wasn't quite sure of their quality. So this is just an amazon link. There are prices about half of this they can be used be this is the problem just should be powered. There are other options out there, so other I don't know how out of this would work with the other options, just figure out for yourself I'm, just not in the American market I'm, not searching that much different hardware, so I can't you.

A

E

um I, don't know whether they are places when this is this available for cheaper price yeah.

A

Yeah yeah very nice, very nice, so next step would be for me to get all the parts and put the system together. So I can test it here and get you that I have to do the new firmware for the 3d printer, so it can identify itself so that you can see the name of the printer I can send it to you but yeah. This is great great work. So please continue.

A

What is your next step right now, so you're we're going to work on the getting the whole image for the complete system or we're not yet I can.

E

Do that, but that's not actually in the difficult state state stage, this can be done within an hour, actually I'm kind of waiting. For you, though, because I need to now kind of feedback on how the structure there are several options, especially for the year for the occiput itself. You can set it up in different ways and I need the kind of default setup that I copy for each instance and I have to know how this should be made in a most optimal way. Right.

A

E

Additionally, it probably would be best if you give me an SSH connection to respond to PI as soon as you su set it up. So I can test the stuff on it because, like I said that the scanners, totally untested and I just need to get it through the step-by-step and explaining this simply won't do and I.

A

E

It will work out of the boxes that simply that's not how coding works. That's right.

A

E

You'll have to test it right, so.

A

How do I give you an SSH connection to the Raspberry Pi? How do I do that.

E

After it's connected to your tree, rather you can set it up, so it is called port forwarding. You can do this on your router and you just set up one specific part, and this is then reachable through the internet and don't panic. This ledge is pretty secure. So it's a secure as your password is for you, you send me, hopefully a pretty good password and then I can log into it, and I can communicate with it like I'm sitting. Next to it. That's that's kind of the warning out there. So pretty easy.

A

So as long as my internet is online and the Raspberry Pi is powered on, you can actually test excessive.

E

A

E

That's that's what I was aiming at very.

A

Nice, so you can actually be making a connection to the printer. You can literally be controlling my printer from your house. Yeah.

E

Yeah I could actually do that. That's a little thing. I wanted to to add, as a kind of bummer to the record system. I can't set up a real, secure way to share this website. I've set up in a secure way everywhere. This is this has several reasons.

E

Main reason is that the octopus has a security system on its own, but this is means that on each click you do a bar on each each printer, your your choosing, you have to login separately and I, think you will agree that that would be just inefficient than just a pain, yeah.

A

E

Just stupid so which, if you want to share this over the Internet as long as it's in your heart, it's no problem, but if you want to share it over the Internet, you will have to set up some really complicated stuff, and if you want to do that, you should contact me again about that, and this would take actually pretty much time and I. Don't think that that's really worth it.

E

But if you say this is important and just look at it, I'll write an API, no, the left, so maybe we can just at this age. This connection I am also using. Maybe we can send over this connection, just a command that can set up the printing process as well about the nice Greek. So just that's! What giving the single yeah.

A

Yeah yeah now that's very interesting in terms of how you can have yeah towards a remote print cluster like, for example, as an enterprise opportunity. You can actually be renting your print cluster through a remote interface to other people. They want to use. It they'll be very interesting that that.

E

Could be done, how hurt there should be another layer of security, so just kind of a page- that's locally there, and there should be in kind of an enterprise page about that. That could also make the pricing stuff. So, like I said this layer of security is only for internal Wi-Fi where, where, where there's a secure, password available or just plugged in into the Ethernet, so nothing with the implant. That would be horrible because of improve accessibility, pretty bad yeah.

A

Yeah, yes, that's very good! Well, that's excellent work, so what I'll do is make sure I can get to that step. Maybe push that up. My priority could be I got to get you that information first, it's that it's about the identity, information and I basically have to do them. Get the Raspberry Pi establish here soon. The.

F

Ants are going to order that next.

A

Thing yeah give it from Amazon em.

E

Yes, I I suppose. Actually you just call me on some point when you have to Raspberry Pi and I'll, explain to you how to open their stage, but maybe you can just help me with the next step on how they should look like exactly. Okay,.

A

E

Yeah I propose that yeah.

A

Yeah, definitely all right so with that said, let's see in the meantime, until that happens, do you want to do any of the the linemen filament extruder work, I.

E

May look instead, but I'm not quite sure on how hot I can get them to that I. Think I can't do that. Maybe what I wanted to ask you is I've got two little prop projects on that one one of the API and once the what are some convert is a conversion so I thought about. Maybe you could just upload there an effort, FC STD file, and this would just be converted into the SDL equivalent and it directly uploaded into the octopi not into the SD card at the octopi repository.

E

So you can just use this directly and don't have any kind of conversion going on, for that. Would that be of interest yeah.

A

So would that be pretty much immediate? You can load the the free CAD file pretty much into the Raspberry Pi, and that will do the conversion and how long would it take? It would be quick, yeah.

E

So it would just be a button on the website, like you know it. When you can upload someone something on the website will look about like that, it will be uploaded and then it will be converted in internal algorithm and then it will be pushed into the repository debt. That's containing the uploads of the octoprint, so you can at once upload it onto your sd card itself. Yeah.

A

E

Of course, gone off, yeah.

A

That process, if that workflow, can be made on clear and no just easy workflow for that yeah yeah. That would definitely be interesting, so we don't have to generate STL files. Whenever we work we just we can just remain at the freecad and send them there directly. I can.

E

Do that it would take half a gigabyte on the system. However, it's one point a gigabyte at the moment, so it's pretty pretty there's not much. Space left as far as I can see are anything for free ten upon it. So this is pretty big.

E

The process would, of course, put the system into a kind of a high working state, but I don't think it'll take too long, so I think.

A

E

Possible that I think I can do this within the week. Yeah.

A

I think that it appears that that might get in a way of the scalability of the Raspberry Pi system. Do you think it will.

E

Well, you shouldn't do multiple at one step: that's that's the thing that could actually really be a problem. However, if you do this only one at a time, so it's nothing to like you, you just there are not ten persons loading up at once, but there's one person that says: ah I've got an SPF, see I can't bring.

A

Her here sorry.

E

um I guess I just just just file my file, so I, look at this file and I've got this file and it's then I don't know. Maybe it will take or something like that. That's just an estimation. I think that will be enough.

E

Maybe it may be five seconds, and so it's only a problem if there are multiple dysfunction at once, I think that that would be a problem. Maybe.

A

E

Have you have to decide whether this distance still useful or not I can't quite I can't quite say that if.

A

It I mean if it doesn't decrease performance, I called.

E

On them upload so only for few seconds on the on upload itself,.

A

E

That there will be not nothing really that would that would slow it down. As far as I can see it, the.

A

Conversion would take I mean it's that's a second, that's a fraction of a second or next few seconds.

E

Probably a few seconds, but outside of that it will take your.

A

E

Time that would be measurable, I, don't think so. Okay,.

A

So I think that's probably how does everyone else feel about it sounds sounds like that's a good good way to go for convenience of printing, so you don't have to keep twice the number of files on the wiki, because now we have to maintain there's the free cat file and then there's the individual print file STL so to combine it into one I think that would be. That would be quite desirable. It seems to me right now, unless once we find some other things that may not work about that, workflow yeah don't be good.

A

Let's go with it now: oh okay, yeah and phase it yeah. And it's like one thing at a time. Can you actually do that yeah yeah I mean I, think I think you're doing doing work pretty rapidly, so I think that would be it'll, be good good to implement that as we get this Raspberry Pi in-house here mm-hmm, let's do it. Let's try it it'll, be great. Don't.

E

Set it I'll do that and a little last question as well. Maybe someone has a spin experience of death because I haven't and if it is a problem, we should of course document that and.

A

E

I have maybe someone has done this when it's printing, so the other Reno is taking G code from somewhere and just printing and printing and doing stuff what is happening if you send from different source so like I'm, sending with my scanner I'm sending a code. This is nothing that would stop the machine or something like that is just resetting a string or something like that.

E

So just sending bit of text, but would it kind of disrupts the workflow and then just stop altogether or would it just be implemented in the current process, as one line would be caught back and then it would just go on like like, like net nothing happens, or what exactly would happen? I'm, not quite sure about that in rows.

E

If it's serving something, then we should got warm up about the use of the scanner, because every printer in the debt that's connected and when, when it's generous use, should of course be them in a suspended state or something like that, so nothing gets gets disrupted. Sorry.

A

You're talking about a scanner.

E

Yeah, sorry, sorry I remind my passing script. What I call scanner that that means it. It's collecting name.

E

A

E

Printers name, but this of course means I sent some kind of G code to the to the printer one of the what happens if this triggers? Actually, at the moment, printing I read.

A

Sure yeah well the way that I don't know how octo print octopi works. But if you look at my screen, if you use I've been using cura, so you start the print before you print you can have you can type in commands and in basically command-line to send g-code commands to the 3d printer once you start it just runs through your file. That's that's all it does, but also lets you stop the print and I and I.

A

Think that probably if you wanted to send some g-code commands, while it's printing I, don't know how it does that it might have that capacity. If not, that would have to be added.

A

Are you actually savvy enough that you can go into octo print and actually start modifying that and.

E

This is not enough, I also princess my auto script for for managing and analyzing what kind of.

F

E

Files there are you.

F

E

A pretty strange world I can't think of what this will exactly. Do I yes.

A

E

No scenario in mentem I hadn't Google that and giving any answers about that yeah.

A

E

I just want to maybe you.

A

Know I, don't know an.

E

Awful word: printing: it is symptoms, temperature, yeah,.

F

E

The kind of question I mean so are operating. You can sense on command that this will be any problem that that's used. You've tested that.

A

um Are you asking me or are.

E

Certain in the in the jet, no.

D

E

So yeah it's kind of from different use people because it's taking the commands from the SD card, so.

E

So it's kind of taken from different part. All that say it's take. It takes us from now source so seeing what this exactly would do well, I think we'll have just to to run it, but the sounds were hopeful that it just will carry on and send you the current text.

E

A

What it, what can yeah we can like if you need to do certain things within G code, I, think the workflow is, you can modify the g-code file beforehand. Would that work for you? You think, because another.

E

This has nothing to do with. The workload is just also looking for 3d printers in the debt that I attach to the pipe. No very.

A

E

And and well I hope, maybe this wouldn't disrupt anything but I'm actually not sure, because when it's printing and I'm sending a code, he sent me your names make with this, would disrupt or or or just ask sir after done or something like that, and then with it would take an hour until the script ends. That would be pretty bad. Maybe 10 hours is a big project and now.

A

E

That would be a pretty what.

A

To test that as we go along and not only other thing, I can say for Oliver is: if Oliver you want to start testing some stuff with Christian as well, please feel free to coordinate between yourselves as well, because you guys are probably act up in one or two hours of each other yeah I.

E

Don't know actually maybe yeah, maybe we can look into that so yeah.

A

Okay, but my tasking.

E

Loggia pretty good yeah.

A

I got it: I got to get the Raspberry Pi here as soon as possible and get it on Amazon and do that? Okay, excellent! So let we can move on then.

E

Yeah I think I'm done here. Sorry for that took so long. Thank.

A

E

Monopolizing it yeah.

A

No, that's good, that's really good progress and and that's a powerful function that we can get and then start spreading the open-source print cluster to the world. That's really good! Yeah.

A

So to conclude the meeting here, then we got to talk about work, work allocation, so there's, let's see who else's is left here, definitely work to be done so Dixon, Roberto and I. Oh, let's see so.

A

A

So, let's cut the print cluster Limon, filament extruder, so yeah we wanted to get some progress going. Just like Roberto did for the big box. Enclosure continue on on all the parts.

A

Let's see so I. Oh, did you yeah? Let's see.

A

Do you'll have for you guys who are here? Do you have enough to go on to continue the work? Let's see Cassie tension mechanism. Can you guys prioritize what Roberto did in terms of so get the get the two dimensional diagram with all the parts and then start filling the labels around it? Just like we have in this document here on slide three and four. We have examples, but let's, let's draw this up at least three through five here this one being the most complete here fully complete.

A

We need to start doing that, for the other one, so next class would be just to start populating. I think this document would be good to work in right in this document here, and you have to set up a new document, but basically take slide six and put in the next. These are all labeled here already, so please continue working in there.

A

Roberto's process is a good guide. That's right for everybody else, so Dixon.

A

You can continue along that iOS got it Roberto. Do you want to pipe into I mean if you don't have anything to do the only thing I can say so you got the STL files to to update but feel free to take on the next. You know the very next one steal it from somebody else who hasn't done. It.

A

A

Yeah going to page, let's go to page yeah, yeah I mean I, guess your barrel, that's vixen, Israel thermal components. Israel started to do some work on the thermal components there. That's that started in in progress and.

A

Then school mechanism- Cassie yeah, will I'd let see you has will done anything on.

A

This yeah yeah, so there's some there's some work here, but we could do the follow roberto's process to the other ones. They'll be they'll, be good Roberto. If you want to jump in to any of the other ones. That's that's.

A

Oh I can say by the way we got to get all these parts in so and drawn up, so we can pretty much do the actual, build and I can actually start printing the parts pretty soon as far as like next week or so so does anyone would that have yeah yeah Roberto I mean please just take.

A

You know, take the next one like whichever ones not started. Just just do it like we, we all want to coordinate so whoever's watching this. A Roberto will Cassie I, o Israel Dixon, look into this working document as the place to coordinate where all the work is. So we know that now here Abe has started this dock, but all the other ones. Please start them right away here: extruder barrel, auger, flange, thermal components, spoiler, electronics, tension mechanism, spool mechanism, so.

A

Yeah, so so please just work right in there and and just take on the next next one. That's not been done. Let's give this get this done as soon as we can, so we can build it just to review on um just in the working working document, critical path for the meeting.

A

The way we're going at this, so here's the filament maker I didn't put too many other steps here. Let's see oh wait it's this would be in a real length to the actual document there yeah the filament maker we've been studying right now, where the CAD phase, the green line is where we are currently as soon as we have all the CAD we're kind of moving through the CAD. We need the full model and part sourcing and build, but at the same time here.

A

We can actually start some steps. We can literally start well I guess on a pant. We can start pretty because I don't have available printer since I'm printing other things. We can start 3d printing, so I'm going to put that in here.

A

If it would, let me 3d printing of parts right there yeah, so please continue on that. I would say Roberto that I think the best one to take take on is which one which one has the least least progress.

A

I would say, jump in just pick one and just dive right in and and if, if we use this document that everyone knows that we can work on this document, what idea is like there's more than one person can be working on on each one of them, so so just maybe Roberto maybe take on the work with Cassie. Take on the tension mechanism and rollers I know she's got a lot of the parts. Maybe do the detail. Diagram like you have and continue working with there.

A

So I would say perhaps join Cassie's effort here on on the roller, the tension mechanism rollers, so whichever okay, so thank you very much, then I think that kind of wraps up the meeting for the week I think all together just great progress on all fronts. We're definitely moving along and we'll see you next week then, and please use the OS, see the 3d printer, open source, ecology, Network page continue.

A

There I haven't really looked at what the updates there are, but I always post the meeting up on a on the main development group, which is the network that open source ecology org. So you can also keep posting there yeah. We had a little down downtime on the wiki, but we're past that there was a service outing and we couldn't get it back online. Okay! Well, thank you very much for everybody, we'll talk again next week, so the next meeting would be regular time, which is Tuesday, 1 p.m. central USA time.

A

So thank you very much and take care till then.
