FAN Wiring Duet 3 MB 6HC

Hussain

Hello,

I am using a Duet 3 MB 6HC to control my 3D printer and am in the process of wiring the machine and getting things working.

I have read the documentation on wiring fans but I have a few questions still.

I need to wire a part cooling fan which is Fan 0 and a cooling fan for the hotend which is Fan 1. Fan1 can be linked to the thermistor of the nozzle.

I am using a 24 V power source.

For wiring Fan 0 which is a 12 V fan I plan to use out_4. My fan has a 2 wires. My jumper pins have 12 v and the center pin connected for out_4 to out_6.

Can I connect the red wire of fan to V_outlc1 or to out4? what's the difference between those two pins?

Attached image of the board below.

For my Fan 1 which is 24 V fan I plan to use out_2. This fan is also 2 wired. I plan on having the red wire connected to V_fused and the black one to out2. is that the correct way to wire the fan ?

Thank you for your help!

@Hussain the V_OUTLC1 pin on each header is the one where either the 12v or 24v +ve comes from.
The duet boards switch things on and off using the outx pin.
So for a standard 2 wire fan, the +ve goes to V_OUTLC and the -ve goes to outx

thank you so much for your response!

I assume the same is true for Out 2 for Fan 1 where V fused is +ve 24 v and out 2 is -ve.

Thanks again!
