Solved Tool Fan turns off at first layer (first Duet project)

[dysseus]

Hello Makers,
I realized my first Duet 2 project. All the base functions are running and are ready to print.
My latest and first unsolvable (by me) problem is that when I start Cura code my Extruder fan turns off when the printer starts the first layer. I assume that it will turn on after the first layer and that the part cooling fan and the extruder fans are connected somehow. Otherwise the extruder fan starts at 45°C as it should.

What went wrong with my setting?

Can you share your config.g and the sliced gcode file from cura? That will show us what is actually going on.

and here's the beginning of the gcode

Edit: I think line 27 M107 overrides the parameter of the config and turns the fan off, even if it's over 45°C...
