This is really impressive

I love it! Good work :)

[@Evezor]

Thank you!

I'm trying to rack my brain what those 10 awesome little fellas could do :) I think a small production line producing something that has a "functional" use would be best. First manufacture base parts then clean them up, assemble and screw them together. I've been recently looking into velomobiles and bicycles. The PodBike is a great example of a lightweight and very energy efficient vehicle that protects you from the rain and might get people to stop driving their big heavy cars so much. But it also shows how expensive velomobiles or more efficient bicycles are. The Podbike optimizes that with an chassis bend out of aluminium and riveted. I realize this is a bad example since it's too big (2.4 x 0.8m) but that is the kind of application where open and distributed manufacturing could really lead to dramatic changes. Anyways, thanks for the video!

Thanks for the ideas. I'll figure out something I'm sure. Food is another kind of easy one.

@@Evezor Oh I've got it! Of course! :D Build tooling that makes battery packs out of 18650 batteries. I think that could be done. The raw price for 18650 cells is like $250 / kWh while finished packs with BMS are like $1000-2000 per kWh. My guess because of the required manual labor and large variation in requirements for cell configuration and current capacity. The parts aren't too large and the tasks aren't that complex. You need to weld tabs and fuse wires to the battery, place them in a certain configuration, tape them together and connect to a BMS. Then put them in an enclosure / wrap them (3D printed enclosure?). If you had a manufacturing path that could also be parameterized to change configuration of batteries and test them this could not only be super interesting, profitable but also a key component to more widespread adoption of cheap solar panels and off grid power. You think that could be done with the evezor? What is also missing is an affordable smart battery like the yeti where you can directly connect cheap 300W solar panels to it and get stable voltage out without having to worry about chargers, BMS or things.

any ideas why one is out of sync with rest?

[@Evezor]

That specific machine has a cheap chinese arduino clone inside and the crystal is very out of spec. They're all a little different, but that one is very much slower than all the others.

[@theodoreburns1330]

Just found this and this stuff is amazing! What do you think is the max payload of this arm? I'm planning on designing something similar (although with a much smaller budget haha) And maybe you could have all 10 work in conjunction to make more clones of themselves! Although that would be no small feat.

Hello from Russia! I can translate the web interface and instructions into Russian, but I don’t see where the language data is stored on GitHub, for quite some time nothing was updated there, even on Thingverse. Sorry for my English if there are any errors. Best Regards Eugene

[@Evezor]

Thanks Eugene! I haven't published the code I'm currently using yet, mostly because it's still very rough and too ugly. I hope to push some more updates in the next week or two. As far as the design files go you can get the latest files directly from Onshape. I've got all the links to those pages on my site at evezor.com/source at the bottom of the page.

[@sdqf]

Evezor thanks for quick reply! Waiting code. oneshape allows you to output stl files to print? Which controller are you using, maybe Ramps? I saw the Marlin source code on Github. Managed to switch to 32-bit?

[@Evezor]

@@sdqf Yes, you can output to stl files from onshape. Also yes, i'm using marlin and the boards can be whatever flavor you like, but you need to break out the reset pin from the stepper driver if you want to have proper homing with the encoders. I'm working on some other hardware that's 32bit but it's still in the preliminary stages. I likely will not be staying with marlin as it doesn't have some of the functionality I'm looking for (and likely never will.)

[@sdqf]

Evezor understandably. Thank you for your project, you have done a great job!

[@sdqf]

Evezor I am subscribers for GitHub and your Site, waiting updates.
