      @Saurabh said in Using FAN Pin as a GPIO in Duet 3:

      Solved the issue, GPIO pin is working when a device is connected to that. Earlier I was checking output on out4 using a multimeter and it was showing almost 0V. Any idea how to detect this pwm signal on out4 using a multimeter or scope?

      Connect a pullup resistor between the OUT- pin and the adjacent positive supply pin.

      ;Gcode using to set output on pin M950 F2 C"out5" Q1000 ; create fan 2 on pin out8 for tickle pulse of frequency 1khz |out8 M106 P2 S1 H-1

      I'm don't have much knowledge of hardware. Can you help me with it? And what more connection can I do.

      Were you using the same cable and connector to connect the Nema 23 motor to the expansion board as you were when you connected it to the main board? If so, and given that you had a Nema 17 motor working with the expansion board (on the same output I presume) then the most likely explanation is that you have a bad crimp on the connector, so that one wire makes contact only intermittently.

      It may help to get a M122 report from the expansion board after trying to move the motor, e.g. if the board uses CAN address 1 then send M122 B1. That may tell you that one phase is open circuit.
