12V LED Strip ond Duet 2 Wifi

xenon2008

Hello!

Can i connect a 12V LED Stripe to a controlled FAN Output?

I have 24V System, but when i wire +/- from the Controlled Fan Output to to Buck Regulator (12V), and from the Buck Regulator to the 12V LED Stripe, that should work?

And if yes, what have i to set in the Firmware?

Sorry for my Bad English, i am a German User with terrible English Skills

Thanks & Kind Regards

Yes that should work.

How do you have the buck converter wired up to the fan ports?

See here for an illustrated example

LEDs: https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+5:+Upgrades/54#s225

Your english seems very good.

Be aware that the regulator should be in the + (positive) (red) side. The buck regulator should have its own ground, NOT to the fan output.

The fan output PWM switches the ground - (negative) (black) side. The fan output negative should be wired directly to the black wires from the LED strip.

Define that fan port as a fan, then use normal fan on, or fan off, commands to turn the LEDs on or off.

I don't quite understand that now ...

I have a 12V Fan connected with a Buckregulator as described here

how do I have to attach the LED strip where exactly or the buck converter?

Kind Regards

Buck regulator input + (red) to + of an always on fan outlet on the Duet.
Buck regulator input - (black) to - of an always on fan outlet on the Duet.

Buck regulator output + (red) to the + of the fan itself.
Buck regulator output - (black) will have no connection.

Fan - (black) to the - of the controlled fan outlet on the Duet.

Which Duet board do you have? Duet 2 Wifi? Duet 3 6HC? I will post a wiring diagram.
