Hello. I have yet to buy and build this robot (but I'm desperately interested and already 3D printed all parts) and I was thinking of ways to use this machine. Is there a way to map the Arduino inputs to control what program the robot runs, ie. running a home position program with one button, running a pick/place program with another button, and running a milling/lathing operations with a final button? Even better would be to connect to an HMI (but that's for later).
