      HI Guys Here I am one more time 🤣🤣🤣

      I have a problem with my Hotend fan, not working. I disconnect it and test it with a 9 volts battery and it woks. The layer fan is working properly ,but not sure if I have something wrong on my setting . Here is my config.g . Thanks Much

      
      ```; Fans
      M950 F0 C"out4" Q500                   ; create fan 0 on pin out4 and set its frequency
      M106 P0 C"Layer Fan" S0 H-1            ; set fan 0 name and value. Thermostatic control is turned off
      M950 F1 C"out3" Q500                   ; create fan 1 on pin out3 and set its frequency
      M106 P1 C"Hotend Fan" S0 H1 T45        ; set fan 1 name and value. Thermostatic control turned on for Hotend

        Have you changed anything in the config recently?

        Try changing the S0 to S1 in M106 P1 C"Hotend Fan" S0 H1 T45

        If the fan works otherwise, check the wiring between it and the Duet for continuity. Check the crimp at the board connector end.

          I did change it to S1. Is there a way to send a gcode and test manually on my board ??

            Yes you can test it manually by sending

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