Actually I'm working on something like what you suggest already, and others have done it as well. On the other hand, real-time control on a cheap microcontroller is not as easy as it seems. Everything has its limitations, and what is just right for one application is overkill for another, or inadequate for something else. The CNC/motion-control market is big but by no means homogenous. -- Phil Mattison http://www.ohmikron.com/ Motors::Drivers::Controllers::Software
