General Mach Discussion / Re: Motor and driver problems. Please HELP

Yes, thank you this is my first post. I have a metal shop in Thousand Oaks CA. Just bought a used router table (not working) and trying to get it operational. The motors appear to be uni-polar (6 wire). The drivers are old but am told they are working. They have built-in power supply. I have the documentation for the drivers. There is a "RUN" potentiometer and a "STOP" potentiometer on the drivers. There are also "+" and "-" terminals for step and direction. Right now I have the step "+" wired to pin 2 and dir. wired to pin 6 (X axis) and "-" wired to the COM pin with both "-" terminals jumpered. I am running Mach 3 through a CNC4PC C10 breakout board. The motors are responding to the up & down arrow keys. The documentation describes the symptoms I'm experiencing and suggests to change the signal timing. Not sure how to do this. By the way, I have 3 matching motors and 3 matching drivers.
Thanks,
Randy
