Hello Art
I'm just having Darwin use frequency control. There isn't enough documentation on Mach 4 on how to configure a step/dir spindle as an OB axis. If you or someone can tell me how to do it I sure would like to try it. Right now I have Darwin configured to switch on a relay for M3 and a relay for M4 and just running frequency into a cnc4pc C6 board for an analog voltage to a KBIC speed controller. I looked at the Darwin configuration under Diagnostics and wondered what would happen if I set the Low hz to 1 under Ferq Ctrl and left the Hi hz at 1000. I closed Mach 4 and restarted and now I can do M3 S*** in MDI and I have spindle movement. So changing 0 to 1 in the Low hz window fixed it.
