Controller fan and part cooling fans not working.
My controller fan does not turn on. I also cant control it on the dashboard. Does it turn on by itself on a given temperature?
Also my part cooling fans dont work. I can control them on the dashboard, but nothing happens.
I havent printed anything yet. Are the fans working like they are supposed to do or is something wrong?

please upload your debug.zip. And also show us pictures of how you have your system wired up
I use a max EZ board and the controller fan is on FAN3 port.
Controller fan only moves when stepper motors are energized. Like after homing or a movement.
okay thank you. what about the part cooling fans? I can adjust the slider from 0 to 100%, but they dont turn on?
Is the configuration correct?
What did you choose in configurator?
