Very nice, Mark. I'm really impressed that you managed to fold this carriage up into such a nice compact unit. And you are really making some great progress. Did you print anything yet?
I've also made some progress but not really thought it through completely... I know I'm facing imminent collision of corexy belt terminations and Z-lift assembly on my version. I'm also thinking laser rather than needle-cutter at this point although their needs for Z-lift range are really quite similar. But, impatience wins, and I couldn't resist printing the main carriage body last night. I seem to work better printing some physical stuff for fit-check and looksee
Worked most of [rainy] yesterday on the CAD stuff... I'm still quite awkward while learning my way around in Onshape... but I finally got to the point I could create an STL

Then I started printing late last evening... it was at 48% when I went to bed. Woke this morning to a finished print... took about 6-1/2 hours (0.25mm layers, 15% infill, and 3 perimeters)

I'll try to populate a basic gantry mockup to see how well things move mechanically before migrating it to my current CoreXY machine. It'll be a trick, I think, getting all the belts attached so I can drive it around... but I really don't have anything better or more pressing to do, so I'll keep piddling with it to see how far I can get before crashing into the wall...
