4028 running at 100% at 1-100
So I just upgraded my bearings to ceramic, while doing those i also updated to the new toolhead beta2. I left my 4028 fan plugged in and did nothing to firmware, but now my fan only runs at 100 %. It is wired as said in ratrig using the bed heater as ground and i have the added fan part in user overrides to use pin PA3 for the heater, the blue wire back to ground on the original part cooling fan pin, and the positive to a always on pin. This is how it was before upgrade and worked fine, no idea on what else to check
