Thanks Andy. Thats a whole class in cnc science all by itself. I think I'll see how it runs in PDM. That mode sounds interesting, and would lend itself to CCS speed control a bit smoother. I'm also trying to setup a spindle-at-speed signal based on the i/o diff of a lowpass filter. Theory being that if the i and o values being a close enough, the spindle is at whatever speed command was issued. But that will need a minimum speed detector. Doable, put everything in low gear and feed the motor 20hz and see what the tach says. My hal file is growing. :) I've not figured out how to set the pdm frequency yet, but I'm sure its in there.
