Question #: 14482

Question: On Mach3 USB the port number is 3 but i dont see the motor output pin numbers for the stepper side? could you please provide this for me? maybe a sketch of all the pin numbers the way Mach 3 sees them?

Current Solution

The step and direction terminals on the Mach3 USB controller are the terminals labeled XP, XD, YP, YD, ZP, ZD, AP and AD. The P is the pulse or step terminal and the D is the direction terminal.

The configuration for the motor outputs are already configured in the Mach3 configuration file that is available on that product page:
