fan on startup

Hello everyone, I would need to turn on the fan, as soon as my printer starts, can you help me? thank you


  • The command for this is
    M106 S255

    Put it where you need it. In firmware you can put it in
    #define STARTUP_GCODE ""

    so it runs when your printer gets power. Or you put it in the start print gcode. You can also configure slicer to always have fan 100%.

    If you need always fan for some reason connect fan to a power socket so it can not be disabled. Slicers add fan commands easily and will disable it normally at end.
