Two Fan Layer 12V PWM over Duet2 Wifi 24V.
-
Good morning
My current setup is a Duet2 Wifi with a Deux5 powered at 24volt.
Since I have to replace the layer fan because the current one (24v) It started to make a hellish noise, I wanted to know if from the Duet or the Duex5, it was possible to power only the layer fans (I will put 2 side by side) with 12volt voltage. I have several that I can use, 2-, 3-, and 4-wire...all very similar to each other...and I didn't quite understand, from the documentation, which is the best solution for more precise and especially safe control.And if so--what should I do.
The fans, for convenience, I would connect them to the Fan3 and Fan4 connectors.
While I will keep the extruder fan on the Duet, connected to the Fan0 connector.I would then have to connect a set of LEDs (9 LEDs in series) powered at 24volt that would light me under the extruder. Right now I have them connected to the Fan2 connector on the Duet and I control it exactly like it was a thermostatically controlled fan.
Any recommendations?Thanks

@bernardomattiucci Duet 2 doesn't supply 12V to the fan connectors; it's selectable between VIN, 5V or external supply, and any voltage applies to all fans. So you will need an external 12V PSU. Wire it like this: https://docs.duet3d.com/en/User_manual/Connecting_hardware/Fans_connecting#duet-2-using-12v-fans-when-vin-is-24v
For the 24V LEDs, you could power and control them from a spare heater output.

Ok.
This is definitely more important and urgent than fans.So I'd better move it to Duex's E2.Heater connector.
Do you have any idea how to activate this output thermostatically?
Meaning. I want E0.Heater on the Duet to start regularly... and when the temperature of E0.Heater exceeds 50°C, only then do I want the LEDs connected on E2.Heater to be turned on...Led solved
Thanks
