    The "FanExtender" seems to work propperly.
    I can put a fan on the 2 left pins and can regulate the fan via inerface.
    How to control the fan on the 2 right pins?

    Hello

    That is a question I´m searching an answer for since more than 3 Year now. I cannot get that to work.

    Best regards

    Hi there. I got my second fan (above my stepper drivers) running by typing "M42 P8 S255". Switching it off is " M42 P8 S0" (all done in pronterface). P8 is the (RUMBA)boards pin for the second fan, S255 and S0 is the speed (check if your board uses the same pins). These two lines you can add to all of your slic3r generated gcode by inserting them in slic3rs "CustomG-code" windows.
