    You need to Enable the servo circuit. Quick look at the manual tells me you use pin 9 on the Digital inputs.
    The way this is done is using relay that turns on all the the drives at same time using the Enable OUTPUT of PMDX. So when Mach3 is Enabled it takes control of the motors.

    So Relay Coil is controlled via PMDX using Enable OUTPUT. Then Run the wire from VDD on drives thru the relay contacts and back to Pin9.
