The crippled motor crippled work on this last week while opportunity remained open. Now I expect to disappear for at least a week and don't know what to expect after that. Really bummed to not do more functional testing because ... I think it would have been fun and exciting. And because I was sprinting for the 'ibles CNC contest and missing that means loss of reward for the sprint. Whine. Pout.

Anyhow...

I did cut the revision mentioned a couple logs ago and assembled that for fit testing and taking notes for assembly instructions and further revisions.

That rev eliminated the remaining blind screws. Now the spindle clamp -- which should be easy to modify/replace -- can be separated from the Z axis without disassembling the slide. Experimentally, it uses some intentional interference to bias which way an otherwise loose fit tightens up. Assuming the material will deform a bit. It seems to work in hardboard - to the extent that it feels solid but no real testing until I don't know when.

Also: I was able to tile the parts within Ponoko P2 dimensions. Likewise for the next rev ready to cut, but NO PROMISE re future revisions.
