Print cooling fan isn't working
I followed this instruction: https://os.ratrig.com/docs/guides/4028, but i can't get fan work ,it spins and not turning off, when i connect PWM wire, print fan LED turns greenish, but not bright as controller fans LED, when i run M106 it activates 24V output in toolboard. I dont know where is problem. when i plug in PWM cable in controller fan pin it turns off.

How is the fan wired up? Where is it getting power, ground, and PWM signal?
did you try
Yes, no success.
Maybe defective board?
Not terribly likely but you could move the blue wire up a port and change what pin is controlling the fan in printer.cfg
Can You help me with that? Maybe hotend fan socket can be used, because now its working from toolboard?
Oh, from toolboard? Hm
That isn't how you have it wired up
Nor how you have it in printer.cfg
RatOS 2.1 solved it. Looks like there was glitch in installation.
Thank You!
