How to use a LED Strip with Duet 2 WiFI?

I think you're overthinking it. The fan ports use PWM by switching the negative side and don't require the 4 pin that a true 4 wire PWM fan does (though that is an option, it's not what you need for a simple LED strip).
Just connect your LED string to Fan2 and control it like a regular part cooling fan.

M106 P2 S255thanks soooooo much

I have a 24v psu so I use a 24v led strip. I first used a fan output, however the voltage drop caused an issue with my other fans. I switch to using heater output 2 and it works flawlessly.

In config. g

No longer used in RRF3.

I have a question here too.
I use that code to configure my LED strip:
M950 F3 C"0.out6" Q500 M106 P3 S0(And I have two macros to turn in on and off via the web or display than.)
So the "controller" is called "Fan 3" on the Display. Is there a way to rename the object? Like I can rename a tool? (563 S"BlaBla")
Cheers, Chriss
-
@Chriss Yes, M106 C"LEDs" would give it the name LEDs.
-
Thanks! Workes as expected.
I expected that in the "M950" because that is the configuration of the object to me and "M106" the "on/off" only. So I did not looked into the docu of M106.
Anyway: Thank you very much for the fast answer.Cheers, Chriss

M42 P2 SxxxDone! When I boot the board the pin is setted "high" and the LED stripe is immediately turned on with the maximum pulse width. How can I set to let the pin low when the board starts?

Make sure the M42 code is in the slicer startup code and NOT in config.g
I put M32 in my slicer start code which calls beg.g and M0 in my slicer end code which runs stop.g
Then I have M42 P2 S255 in my bed.g and M42 P2 S0 in stop.g and cancel.g

already done but the stripe turns on when I boot the board even without m42

@the_dragonlord can you share your config.g file?

uh, I forgot to say that I'm using a PWM fan not an heater.....sorry....

Which fan header and where is the gcode defining the pin?
-
@the_dragonlord your problem is you have m106 P2 S1 H-1 and you should have m106 P2 S0 H-1
-
@the_dragonlord but I recommend you use a heater and not a fan

i can't use a heater because I have to trigger a mosfet to drive the stripe and overriding a heater pin it gives a level of tension not enough for the mosfet to switch. Ay niw I'm using the Fan 2

excellent, thanks!

@the_dragonlord I'm driving the LEDs directly from the board so that I can control the brightness. But if you are driving a MOSFET, then the fan is a better option I guess.
