Fan control (manual)



  • Hello everyone.
    I have no control of the Part Fan (the one on the right hand side that cools the plastic that has already been extruded) from the LCD of my Ender3 printer

    Going to Control\Temperature\Fan, I should be able to ask the fan to operate at any speed I want, ranging from 0 to 255. Whatever setting I put in there generates no action whatsoever from the fan.

    If I introduce the same commands into a gcode program on the SD card, and run the program, then the fan does as asked.

    What have I missed?
    How can I recover (or obtain) control form the LCD screen (i.e. in a manually controlled way)?
    Anybody who can help me, thanks a lot
