Hi, Tybrenis
First thing to try is in motor tuning set the Step & Dir Pulses to 5, Don't forget the Save Settings, (This gives your stepper control more time to see the Pulses sent out by Mach).
If that doesn't help, In Ports & Pins, Motor Outputs set the Dir & Step Low Active to a different State (X to Check or Check to X), By clicking on it, Don't forget the Apply, (Some stepper controls are sensitive to leading and Trailing Edge Pulses).
Steps Per sets # of steps to move 1 unit whether Inch or MM.
Vel. sets Max speed (Try 50 to start, Set it up till it misses steps back it down some till no steps are lost)
Accl. sets rate from dead stop to max Vel speed. (Try 10 to start, Set it up till it misses steps back it down some till no steps are lost)
Others may have more specific information on your control.
Hope this Helps, Chip
