Part Cooling Fan not working

[TRATOON]

My part cooling fan is always running at a certain speed and doesn't change at all with commands (M106) or using the DWC.

Here is my config:

Have you used that fan successfully elsewhere to know that it accepts PWM speed control?

You can try altering the M950 Q parameter higher or lower to see if you get better control.

[TRATOON]

@Phaedrux I have already tried increasing Q value (250, 10, 5000, 1000, 10000, 100000, etc.) I have tried a known good fan, still 100%. I just read this post https://forum.duet3d.com/topic/18350/duet-toolboard-fan-issue and the user had a similar problem they said that they put their fan on the PWM pin. Right now, I have a two-wire fan on out 1 connected to GND and VOUT is this correct or do I switch wiring.

How exactly is your fan wired?

[TRATOON]

@Phaedrux My part cooling fan has + wire to out 1 +VOUT and the - wire to GND it's a two-wire fan.

[Phaedrux]

Then yes, you need to switch the - wire to the pin labeled "out1" on the wiring diagram, which is the pwm capable pin.

Attaching the negative wire to ground will just be always on.
