@jay_s_uk Hello, the command was actually commented out, but activating it didn't change anything.
The error message comes:

@axiom so a couple of things about your config.
You only have a hotend cooling fan defined so that will automatically come on once the hotend reaches 45 degrees and will run at a constant speed and won't be controllable thought DWC.

You have the config for your part cooling fan commented out so it won't function. This also results in you have no part cooling fan mapped to your tool (your commented out part cooling fan is F0 and that's what you have mapped to the tool), resulting in the errors you see when the gcode tries to change it, as it doesn't exist.

[axiom]

@jay_s_uk
I do not understand that completely. I don't want to activate Tool 0 and Fan 0, it's just about Tool1 and Fan 1.
I also commented out the M106 command and the controller in the DWC is visible and active.here is also no more error message. But the fan is already running when you start it... could it be a hardware problem?

[axiom]

@axiom even if I comment out all fans, the fan doesn't work...on the other pins..I plugged it into fan1

[axiom]

@axiom I have now rewritten everything to fan 0 and it works....what can be broken on the board...can I fix it?

[dc42]

@axiom how many fans have you connected to the board, which outputs have you connected them to, and what does each those fans cool?

[axiom]

@dc42 Originally I had planned and installed 2 print heads. But for testing only one is active. I have one for the print head (continuous ventilation) and one for the workpiece to regulate).
Everything works too...but unfortunately not on the Fan1 pin...if I adjust it...there is a permanent ventilation. Currently I have changed the sim code and the hardware to Fan0 and everything works... could it be that the Fan1 pin is defective? but how can i fix this? It looks good visually, but I can't look at the back without disassembling everything

[dc42]

@axiom how long was it working for before you found you could not adjust the speed? Did you change anything?

The Fan1 mosfet could have failed short circuit.

[axiom]

@dc42 It worked around 3 months. How coul i fix the shortcut at the fan1 mosfet?

[Phaedrux]

Can you grab a photo of the mosfet? Sometimes they appear damaged.

Otherwise you can use a multimeter to check them. Though they are quite small, so you need to be careful with the probe tips.

https://www.youtube.com/watch?v=RkWy1EirEu8

If they are failed, they can be replaced. https://docs.duet3d.com/en/User_manual/Troubleshooting/Parts#fan-mosfet

They typically fail if the fan short circuits either through the wiring or internally to the fan. Does the fan still work when connected directly to voltage?
