Finally an engineering design to really motivate me to continue learning freeCAD, fidgets are nice but still toys. Subbed to see the end result of the CNC. Weird that it takes one to make another CNC.
The CNC is coming together surprisingly well. I have the frames and gantry welded up, and I can sit on the gantry without noticeable deflection (probably need at least 500lbs to make the gantry deflect visibly, or maybe twice that). Next is to weld the brackets for the ballscrews where needed, and then it's ready for a coat of paint and assembly and wiring. So far, it's gone smoother and better than I had hoped. The beefy gantry rolls really smoothly, and is obscenely rigid. Having a solid design, where many of the kinks were ironed out virtually beforehand, really cuts down on the real-world manufacturing time. Lol. I love the remark about CNCs making CNCs. I often think about how I would bootstrap industry in extreme scarcity (like, a crashed spaceship, could we build a working spaceship from the parts of the larger craft? Or if all supply chains failed, how could we rebuild a modicum of manufactory amidst an apocalypse?) The result seems to always be that, as most parts for very sophisticated devices will need to be machined into existence, there's something of a sequence to the types of tools and devices you need. At first, crude hand tools to make better hand tools, then manually operated machines, then more automatic machines, and finally the specialized equipment to make the finished parts. This CNC is the second-to-last step in the chain. There's a few machines we'll be building in the relatively near future to manufacture the flexible and rigid components of the muscles we'll make for Nephele's upper body, and we'll use most of my existing equipment to make those machines. I'm stoked you brought it up - it's a fun idea I've been toying with as I've worked through the process of building stuff. I even mentioned it during the recording of the narration on a couple of my videos - including this one, but I always cut it from the final video. I'm glad there's like minds out there that are into this kind of stuff!
There's a bunch of Octolapse timelapses in this video. I threw in a little bit of real-time recording of the printer, too, but there's maybe 12 or 15 Octolapse timelapses in this video where the part just looks like it's growing in place. I agree it's a great plugin, and a must-have for UA-cam if your printer's bed moves.

Could you please do a tutorial on designing a planetary geartrain in freecad
Ok. I did, lol. ua-cam.com/video/qsMan12GRtU/v-deo.html
hi nice work in freecad; just hoped for a bit more explanation rather than a speed modeling montage. keep up the designing
Thank you. I appreciate the feedback.
Have you looked at the Octolapse plugin for Octoprint?
The resulting video of the prints are far better.
