I've been wanting to come up with a proportional (further you push, faster it goes) joystick based controller for Mach 3 and I'm having a little trouble with the last piece of the puzzle. Basically, this means that I won't need to stop and switch "speed" settings on a pendant in order to drive quickly across the table and I'll be able to drive two axes simultaneously on each joystick.
I programmed a PIC chip to translate the analog input from the joystick to digital step/direction pulses. I'm now trying to figure out how to interface those signals to Mach 3. I made the mistake of assuming this would be a simple task (a hazard of living so much of my life on the road is that I have lots of time to program stuff like this, but very little time to work on actual hardware).
