I am trying to drill a very small hole with my cnc router. However, I am not sure how to set up Mach 3 for very fine xyz movements when I am trying to zero the tool. I am using a keypad and the "key grabber" for the movements. However , I'd like to be able to push a key and translate either xyz into very, very fine movements, i.e., .001 at a time. I hope I don't have to change the motor or driver configuration settings.
thanks
