I appear to be on the bleeding edge of mach control. I am using the latest version with smoothstepper with a pendant on lpt2, SoundLogic breakout and homann designs digispeed and ModIO. Everything was working until I threw in smoothstepper. I now get a change in the DRO readout in MACH when I jog but no pulses to the gecko 320's. I know its a smoothstepper problem but what? I am using SoundLogics pins, all of the lights on smoothstepper act as they should. Mach is communicating with smoothstepper.
