All,
I have a unipolar stepper driver that I'd like to connect to a USBCNC controller.
I believe the step / direction inputs to the unipolar driver use a common ground (common anode?). The USB CNC has a common 5V (common cathode) system. It that the purpose of the pullup disables?
Can you guide me to the orret wiring?
