Solved Part cooling fan and extruder fan are constantly on
-
I am trying to set up my part cooling fan and extruder fan, but it appears that out4/5/6 on my board are constantly on. It is a Duet 3 MB 6HC, and the jumper for out4/5/6 is jumped for 12v. The fans I am trying to run are also 12v. M106 is giving me no control over them also. Any help would be greatly appeciated! attached is my config.g file also

The config looks ok
; Fans M950 F0 C"out5" Q500 ; create fan 0 on pin out5 and set its frequency M106 P0 S0 H-1 ; set fan 0 value. Thermostatic control is turned off M950 F1 C"out6" Q500 ; create fan 1 on pin out6 and set its frequency M106 P1 S0 H-1 ; set fan 1 value. Thermostatic control is turned off ; Tools M563 P0 D0 H1 F0 ; define tool 0
Have you tried setting up with one of the other outputs?
Photo of the wiring?
It's possible the mosfets are damaged and failed fused in the on position.

@phaedrux Thank you for the reply. I have tried all of the outputs 4/5/6, which are all of the PWM controllable outputs to my knowledge. Attached is a picture of the extruder fan and part cooling fan wired to output 5/6

You have them wired incorrectly, you want the 2nd and 4th terminal.
Check the wiring diagram here, https://duet3d.dozuki.com/Wiki/Duet_3_Mainboard_6HC_Wiring_Diagram.

@rushmere3d Ah I see it was wired to v_in + gnd thats why it was always on with no control. Thank you so much! They are working fine now
