      Hi, im sad to tell u that i shorted by mistake two of the PWM outputs (fan0 and 1), and they stopped working. Fan 0 not even turns on, and fan 1 cant be controlled anymore by the M106 Command, so there is a chance that i blown the pin of the uC.
      Is there any way to use one of the expansion pins as a PWM output?

        It sounds like you've damaged the fan mosfets.

        They can be replaced with some difficulty.

        You can use an expansion pin for a PWM signal, but they can't drive a fan by themselves. See here: https://forum.duet3d.com/topic/24053/assigning-fan-with-m950-to-expansion-pins/2?_=1630692789984
