Duet 3 2 wire Fan

[roth]

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

Thank you, have been looking for this information for a while concerning the V_OUTLC1 pin and wiring of 3 wire fans.
