Blower fan changing speeds for split of a second
Hello All,
I have changed the firmware of the printer to 3.6 and since than (might be from before but I just realized), the blower fan peeks speed for split of a second every 3-4 seconds.
anyone have a clue where this is coming from ? Changed the fan back to the original prusa one, same situation.

it is something with the electronic board as the led light above the fan socket is blinking even when the fan is unplugged...

this is normal and a known result of the PWM changes to the firmware. I'm not sure if it's a bug or intended as such because the PWM changes introduce challenges in detecting the fan RPM.
