Mo-Co Dolly, Rough Assembly

A test assembly of the in-work motion control dolly. Not everything is bolted down tightly yet, this was just to see if it would all go together, and when it did, if it would run.

And run it did.

Took a little more power to drive the carriage than I thought it would, but the motor shield on the Arduino didn't even get noticeably above room temperature (unlike the other one whose bridge I burned out with no load on the motor -- oops).

The Delrin coupling seems to be a tiny bit off-centered, but it's just a fit-up problem -- close enough to proceed with finishing the assorted aluminum bits and wiring up the limit switches.
