Hello all.

I installed a PWM fan for my part cooling. The problem is that the fan is always running even when it is not printing. Can't change on/off state of the fan on Klipper either.

I am using the SB2209 (RP2040) toolhead PCB.

Got it working by plugging the power to the part cooling terminal instead of the PWM terminal.
