    I had to change my pwm ports because I shorted the ones I was previously using.
    Btw. I tried it with your adjustments but my hotend fan is still not turning on when my heater reaches 50 degrees.

      @maroonds You made the changes to config.g, saved it, then reset the Duet? Run M98 P"config.g" and see if it generates any errors.

      What happens if you send:
      M307 H2 A-1 C-1 D-1
      M106 P1 A2 H-1 S1

        @droftarts It doesn't create any errors and after I pasted the other commands nothing happens and the fan still doesn't turn on at 50 C

          @maroonds Can you post a picture of your board showing wiring? How are you connecting the fan to E1 HEATER, on the pins or screw terminals? Have you checked polarity?

          The command from my previous post, M106 P1 A2 H-1 S1, should turn it on full speed straight away, to test. To be thermostatic controlled, needs to be M106 P1 A2 H1 T50. But it needs to be working with the first M106 command, before setting it to thermostatic control. See gcode dictionary to understand the settings: https://duet3d.dozuki.com/Wiki/Gcode#Section_M106_Fan_On

            M106 P1 A2 H-1 S1

            Screw terminals. I checked the voltages with a multimeter and it has around 0.5V with this command sent: M106 P1 A2 H-1 S1
            And yes the polarity is right

              @droftarts This was my setup on RRF3 (now I'm on 2.05.1):
              ; Fans
              M950 F3 C"e1heat"
              M106 P3 H1 T35 S1
              M950 F2 C"nil"
              M950 F0 C"fan2" Q500
              M106 P0 I0 C"5015" S0 H-1

                @maroonds try S255 . Any reason you rolled back from RRF3? Where the fans not working? Setting the part cooling fan with P0 and not thermostatic or bound to a tool should put it under slicer or manual control.

                As this is a Maestro, I’m not sure if pin A2 is correct for Heater 1. It should be. @dc42 ?

                  @droftarts I don't know what I did wrong yesterday, but now it's working.
                  At least this command: M106 P2 A2 H-1 s255
                  But how can I make it thermostatic controllable?
                  This is my current setup:
                  M106 P0 A22 H-1 S1 ; Part cooling fan
                  M106 P3 A2 H1 T45 ; Hotend fan
                  M307 H2 A-1 C-1 D-1 ; Disables H2

                    The M307 command must come before the M106 P3 A2 command.
