Duet 3 2 wire Fan



  • Hello

    i want to install a 2 wire Fan.
    But i have the Problem the Fan is always on.

    I connect it to GND and V_OUTLC1

    M950 F0 C"out4" Q500                               ; create fan 0 on pin out4 and set its frequency
    M106 P0 S0 H-1                                     ; set fan 0 value. Thermostatic control is turned off
    M950 F1 C"out5" Q500                               ; create fan 1 on pin out5 and set its frequency
    M106 P1 S0 H-1                                     ; set fan 1 value. Thermostatic control is turned off

  • v_outlc1 is a fixed voltage and ground is a fixed voltage.

    you need to connect the fan between v_outlc1 an out4 to be able to control the fan with M106.

    seems https://duet3d.dozuki.com/Wiki/Connecting_and_configuring_fans isn't updated to reflect the naming of the duet3.

    vfan = v_outlc1
    vfan0- = out4



  • Thanks works fine.
    pin 2 and last pin.
