Hi Rich, Switch de-bounce logic in the Arduino would be a nice feature.
I'm thinking that probably I could offload most or all of the motion engine to the Atmel µP. That would be desirable to to keep motors synchronized within a half micro-step while doing linear and circular interpolation. Probably it would also be desirable to process limit switch input in the µP.
