I am using the DM542T driver with a NEMA 23 stepper motor.
This is how it is wired.
The program in the Arduino UNO is a basic for loop that alternates between high and low with a delay after each. The motor is not rotating.
I used a multimeter to confirm the following:
24V power at +Vdc
12V on all four motor lines (A+, A-, B+, B-)
5V signal alternating on and off at PUL+
Regardless of what the Arduino program is doing, if the driver has power and is receiving alternating high/low pulse signals, it should rotate.
I have a second DM542T driver connected to a NEMA 17 motor. All voltages confirmed as above on the second driver and also no motion. It is highly unlikely that both drivers and motors are bad so I must be doing something fundamentally incorrect.
