After 9 days of printing (almost non-stop) and another week of assembly (evenings), here’s my machine moving on its own!
I used the tape-measure cable chain trick for X and Y. That’s the clicking sounds you hear in the video.
TODO:
Connect the step-down to power the Raspberry Pi from the RAMBo's power brick.
Connect the relay for turning the tool on and off.
Trim up the wires to an appropriate length
Design an enclosure for the RAMBo and Raspberry Pi with mounts for the relay and power brick
I'd like to use some small-diameter acrylic rods to bring light from the status LEDs to the surface of the case - same idea as an edge lit acrylic sign. Do you guys think that'll work?
You could probably keep it the way you have it, just needs an L bracket coming off one of the top bolts. If that makes sense. Hang on, I can draw something on my phone, I’ll update in a couple minutes.
There we go. I can’t tell how much room there is, might need to be a U shape, but you get the idea.
Today, I started working on designing a case for the electronics. I haven’t tackled auto-squaring end-stops yet, but that won’t really affect how I design the case.
I spent the day measuring my RAMBo, LCD, and Raspberry Pi, and transferring all of that in to Fusion 360. I printed a few layers of bits and pieces to make sure all my screw holes lined up and everything was laid out properly.
Oh, and I made a thing to “route” light from the status LEDs through some acrylic rod to the outside of my case, just like an edge-lit sign. https://www.thingiverse.com/thing:2945100
Ugh! My Fusion design got corrupted… It won’t even open the previous version. I learned a lesson - save often, then export & use real version control if it’s something you really care about.
I have lots of STLs I can measure, so it’s not a total loss. I posted in Autodesk support, but I’m starting over while I wait for a response.
Yeah, it’s a pretty good way to store stls. It’s not as friendly to share as TV though (searching, or just exploring remixes or looking through tags is a great way to find projects on TV).
Yeah. I’m just using GitHub for version-controlled storage, not collaboration or publishing.
Fusion 360 froze while editing a sketch and my whole “file” (blob of data in their cloud) got corrupted, so I had to start over. It wouldn’t even roll back to a previous version. Now I export the f3d and stl every time, and git commit / git push.
I cringe whenever I learn how any other version control system works. I’ve been using git (but not usually github) since we switched from CVS about 10 years ago. I hate every other vcs. I guess that makes me a snob…
