Using FAN Pin as a GPIO in Duet 3

[Saurabh]

Hi Sir @dc42 , I've Duet 3 6HC V1.0 I want to use FAN out pins(out4, out5, ou6) as a GPIO out pin. Tried configuring the pins using

; configuration
M950 P0 C"out4"
M950 P1 C"out5"
M950 P2 C"out6"
 
; console
M42 P0 S1          ;  turn on pin out4 
M42 P1 S1          ; turn on pin out5
M42 P2 S1          ; turn on pin out6

But there is no output.
Tried Inverting pin. Nothing works.

How can I use this pins as a digital output pins?

Thank you.

Can you post your full config.g?
Can you send M122 and M98 P"config.g" and post the response?

What are you trying to control?

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.
