      Goodmorning everyone.
      I missed something, and reading the documents I didn't understand.

      • duet 2 wifi;
      • tronxy x5sa;
      • all the fans are 24v two wires.
        Can you explain the connection I have to make with the radiator and hotend cooling fans to be controlled from the web console and gcode?
        Thanks for your help.

        the default setting from the configurator should produce the required config.
        did you make any changes to that?

        check the wiring diagram.

        the fan headers have a v_fan pin which is the red wire and the other is the black wire.

          Fan0 is typically the part cooling fan and Fan1 is the hotend heatsink fan.

            I connected them here,
            fan.png
            they turn on at start-up that of the hotend turns on when it reaches temperature.
            But I can't control and / or turn them off.

                  M950 F0 C"fan0" Q500 ; create fan 0 on pin fan0 and set its frequency
                  M106 P0 S0 H0 T45 ; set fan 0 value. Thermostatic control is turned on
                  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

                  you configured both fans to be non controllable.

                  change first one to

                  M106 P0 S0 H-1

                    Thanks a lots

                    the new configuration will be like this then

                    M950 F0 C "fan0" Q500; create fan 0 on pin fan0 and set its frequency
                    M106 P0 S0 H-1 T45; set fan 0 value. Thermostatic control is turned on
                    M950 F1 C "fan1" Q500; create fan 1 on pin fan1 and set its frequency
                    M106 P1 S1 H-1 T45; set fan 1 value. Thermostatic control is turned on

                    Also I wanted to ask if there is any other optimization I can do for the speech fans.

                    I was advised to keep the hotend fan off when printing both PLA and PETG. How do you manage them?

                      i dont think you used the right words here. do you mean noise?

                      PLA wants cooling.
                      pets wants a little bit of cooling

                      That is managed in the slicer fan setting

                          what do you mean by optimizations?
