The avr processor family is more than adequate for human interfacing, a single axis controller, or a tool changer, as I expect you're finding. The 20 MHz parts are even overkill for some of these tasks. I don't see any Xmega macros in the latest Eagle "Atmel" component library. (I'll have to check up on device availability, and make one, one evening.) With up to three hardware quadrature decoders, and fancy PWM hardware, it is tempting to put a cpu and at least one H-bridge on a board, if only to gain familiarity with the newer sub-family. There seems to be widespread [AVR|Arduino] familiarity amongst EMC2 users, so there may be scope for cooperative development of useful modules.
