Hi, New To This
Check in Mach3 top Config, Ports Pins, Motor Outputs, the pin assignments should be as below, also make sure all the Step, Dir ports are
assigned to the same port, then click on Apply, OK
SIGNAL Pin SIGNAL Pin
STEP X 2 DIR X 3
STEP Y 4 DIR X 5
STEP Z 6 DIR X 7
STEP A 8 DIR X 9
You may need to setup the Config, Motor tuning after you get them working, to calibrate the Steps Per (number of step's to move 1 inch),
Velocity ( max speed with no missed steps) and Acceleration ( start speed with out missing steps)
If you change any of these remember the Save Axis Settings for each Axis.
Hopt this Helps, Chip
