duel 3 mini fan

peter247

O.K , Slowly wiring up my Duet 3 mini and understand the jump from the duet 2 wifi and the duet 3 mini.

I have 24v fans same as Vin , So question 1 , What two pins do I use GND and outx- or V_outlc1 and Gnd , I think that is a lower voltage pin , But why GND and OUT minus ?.
Question 2 , By default is the jumper set for 12v fan 3 / 4 and Vin 5/ 6 ?

@peter247 V_outtlc1 and out- for two-wire fans that you want board PWM control on.
There is an extra ground because out- is the side that does the switching, not the input voltage (outtlc)

probably. Choose what you need

The fans need to connect to the positive voltage side and the negative voltage side, not to ground.

V_OUTLC1 and OUT3- for instance.
