PWM fan wiring



  • Want to make sure that I'm wiring this fan up to the duet3 the correct way since they are so easy to fry. I have a 4 wire fan. Black wire>Gnd, Yellow wire>Voutlc1, Blue wire>Out4, Green wire>out4.tach.

    The firmware

    M950 F1 C"out4+out4.tach" ; create fan 1 on pin out4
    M106 P1 S0 H-1 ; set fan 1 value. Thermostatic control is turned off

    That looks sensible, but I haven't seen your fan pinout. Do you have a link to the fan?
