Yeah temps at both the hot end and the bed seem fine as I turn them on or off.
I’m more concerned that the Mosfets heat up so quickly, basically one or more of them instantly heats up and starts to smell which has never happened before. The Mosfets heat up without me turning on the bed or the extruder, it happens as soon as the +12V power is turned on.
