Great to hear you like the idea, I have been away from the project for a week
I'm thinking contraptor is the first step in a bootstrapping cubespawn set! sequence like this:
Start:
Minimum Requirements: Hand drill, miter saw, drills, (other tools) parts and raw materials…
Prefered tool set: Powered Miter saw and a drill press + other stuff
build jigs for drilling aluminum angle, drill 'em
lather, rinse repeat for other basic parts
Add cubespawn frame (12 sticks of 80/20 1010 aluminum 449 mm long(17.677"), 8 corners, 24 bolts)
Build cubespawn frame, use contraptor motion, make cubespawn parts
Finish cubespawn mill
Make a CNC contraptor set
Make Linear steppers on cubespawn
Use contraptor for custom functions within your cell-set
and someday: melt down the handmade cubespawn and the handmade contraptor sets to re-use thier materials in the furnace, re-melt, and extrusion cubes… ;-)
Now you may ask: "Why not just stick with the contraptor?" and I reply: cubespawn is what you build once you've committed to a design, contraptor is how you explore that designs specifics… different, complementary FMS tools! exciting stuff! I wish the Shan Zhai Ji (山寨机) builders would now join us and advance the design…, maybe we can contact them…
