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:
Just a suggestion, move the cable chain to the carriage, not the top of the z. It can cause issues, might not, but it is a possibility.
Thanks for the suggestion! Flipping the cable chain from vertical to horizontal shouldn’t be too difficult.
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.

I went with drag chain setup and it is working great.
I found it over on Thingivers.

oh that’s sweet. Printing one up this evening.
Yesterday, I got my relay cutting the tool on and off now.
Nice, Don’t walk away from it though!
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
No way. I don’t even like to let my MK3 run overnight, and that fancy hot glue gun on a robot arm is way less scary than my DW660.

I also like to live dangerously…

Dang!
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.
GitHub renders STLs in the browser. Check it out!
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.
My rebuilt case prototype, with a case fan at (what will become) the top.

I chose the fan because it had a mechanical drawing. It was wrong.

Dang all the way to a V8… I usually get to about 3 and call it a day. It will be a great feeling when you work it all out and have a finished box!
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…
