      I updated fan 2.

      However I haven't managed to make fan 1, which is the extruder cooler fan stop and turn on when the heater turns on.

      ; Heaters
      M308 S0 P"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin bedtemp
      M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0
      M307 H0 B1 S1.00 ; enable bang-bang mode for the bed heater and set PWM limit
      M140 H0 ; map heated bed to heater 0
      M143 H0 S120 ; set temperature limit for heater 0 to 120C
      M308 S1 P"e0temp" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin e0temp
      M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
      M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
      M143 H1 S280 ; set temperature limit for heater 1 to 280C
      M308 S10 Y"mcu-temp" A"MCU" ; defines sensor 10 as MCU temperature sensor
      M308 S11 Y"drivers" A"Duet stepper drivers" ; defines sensor 11 as stepper driver temperature sensor

      ; Fans
      M950 F0 C"fan0" Q500 ; create fan 0 on pin fan0 and set its frequency
      M106 P0 S1 H-1 ; set fan 0 value. Thermostatic control is turned off
      M950 F1 C"fan1" Q500 ; create fan 1 on pin fan1 and set its frequency
      M106 P1 S1 H1 T45 ; set fan 1 value. Thermostatic control is turned on
      M950 F2 C"fan2" Q100 ; create fan 2 on pin fan2 and set its frequency
      M106 P2 H10:11 T40:70 ; set fan 2 value

        If configure that fan to non-thermostatic control can you then set it's speed using it's DWC fan speed slider?

          Or send M106 P1 S1 H-1 That should turn it on full blast.

              @phaedrux That's the problem. The extruder fan, NOT the part cooling fan is running full blast. Allways. Usually these fans turn on after T45celcius automatically

                Sorry, can you clarify which fan is connected where?

                What happens when you send M106 P1 S1 H-1 ?

                  Sorry but I don't understand what you mean by that.

                  I was wanting you to verify that whatever output you were using was still working.

                    Ok. First things first.

                    Phaedrux, I sent M106 on config file. Nothing changed. Fan stays ON no matter what. FAN 1 was added as option on DWC screen, but it cannot be controlled, which is correct, as the fan is connected in a non PWM output.

                    dcwilt, the extruder heater fan and the motherboard fan are connected in a NON PWM output, but they allways stay ON, full blast no matter what....
                    I wanted to turn them on via thermostat, as they should work. Am I missing something???

                        Yes, M106 P1 S1 H-1 will disable thermostatic control and turn the fan on. Send M106 P1 S0 to turn it off again.

                        Fan1 port is indeed PWM controllable.

                        Fan0, Fan1, Fan2 are controllable. Plus two more always on fan ports.

                        Which are you actually plugged into?

                        Fan0 1 2 can be used as thermostatically controlled or by the slicer to set speed for part cooling.

                        The always on ports are... always on.

                        If you send M106 P1 S0 and the fan won't turn off, then either it's plugged into a different port than you are expecting, or the fan mosfet has been damaged and failed in the on position.

                          It sounds like you are referring to the "always on" fan outputs - they are not controllable.

                            I have plugged those two fans on the allways ON ports.
                            So, after reading your comments, I assume that they cannot be thermostatically controlled???

                              They cannot be controlled in any way. They provide power to the connected fans when power is supplied to the board.
