Newbie here. Working the initial configuration and the motor will only turn one direction, Mach3 Program Run page shows numbers increasing and decreasing. Using a laptop USB to UC100 to breakout board to DM542T drivers to stepper motor. I'm only troubleshooting one drive, once I get this working then I'll work on the others.
Any help would be greatly appreciated.

Have you assigned the step and direction pins correctly?

what Pins are you sedtting mach to out put step and direction signals from?

@natefoerg,
Thank you for the reply. It turned out I did not have those configured correctly. I went by an incorrect video that had me using +5v for the PUL+ and DIR+ pins with the pulse and direction wires going to the PUL- and DIR- pins. The correct way is to have gnd going to the PUL- and DIR- with the pulse and direction wires going to PUL+ and DIR+.
This is all a big learning curve so thank you again for the help!
