    Hey,

    so after i got my duet 3 mini now just running fine, im running into a problem with the hotend fan.
    So i set my Hotend fan as a thermostic fan to run if the hotend goes over 45 degrees celcius. The fan also starts running when the hotend hits that temp, but rather kind of slow and making weird noises. If i then set the "Tool Fan" speed in the DWC to 100% it just runes fine.

    this is how im creating the fan in the config.g

      @staticred also setting the fan as not the tool fan did not chage anything for me. If i run the fan as completly without thermostic control it just runes fine.

              @staticred said in Thermostic fan not spinning at 100%:

              If i then set the "Tool Fan" speed in the DWC to 100% it just runes fine.

              This shouldn't control the thermostatic fan at all. I think you have both fans bound to your tool.

                @phaedrux Yes i had the wrong fan selected there. I now changed it to my other fan it works fine.
