      Some Help Please, I've been at this for 3 days !!
      Wiring is sound,
      Fan 0 Part cooling
      Fan 1 Hot end

      I cannot make the part cooling fan work.
      If I swap connections the part cooling fan works but the hot end, hot end fan and LED's on the smart effector will not.

      This is driving me spare, any assistance would be appreciated.

        Can you paste the results of M115, please.

        So you cannot control the fan from DWC using the slider?
        The fan works directly connected to the PSU?

        Try taking the F500 out of that line, it will make it use the default PWM frequency of 250
        From the GCode bible https://duet3d.dozuki.com/Wiki/Gcode#Section_M106_Fan_On
        The F parameter sets the fan PWM frequency, in Hz. The default is F250, which works with most fans, Try F100 or lower if you find that you can't control the speed of your fan.

        HTH

          Sounds to me like you have borked (technical term) the fan 0 output.
          I don't know if the Maestro has extra fan outputs but if it does, I would use one of those spare outputs and see if you can get it going that way. If that works then it is likely a defective output FET on the fan 0 line.

            Hi Paul many thanks for your reply,

            M115
            FIRMWARE_NAME: RepRapFirmware for Duet 2 Maestro FIRMWARE_VERSION: 2.05.1 ELECTRONICS: Duet Maestro 1.0 FIRMWARE_DATE: 2020-02-09b1

            Fan works fine connected to PSU

            On Fan 0 the Fan does not work at all.
            If I connect it to Fan 1 it works and I can control the speed with the slider in DWC
            However the hot end ,hot end fan and LED's on the smart effector does not work on Fan 0

            I can change the Part cooling fan to Fan 2 and it works but is really under powered.

            Thanks Kenny.

              Do you have the voltage select jumper for Fan 2 set to the correct position? On the Maestro, fan 2 is separately selectable between VIN and 5V.

                Many Thanks for that, Nope I had not, Thankfully now working,
                Any Thoughts on why Fan 0 is inop?
                Thanks Kenny.
