I’m having a rather strange problem with my Ender 3 V2 that’s causing me to leave it unplugged and as a result underused.

I used to have my printer set up in my garage but one day noticed that the circuit breaker was tripping overnight resulting my refridgerator to turn off (not ideal.) I kept removing devices until I determined that it was caused by my 3d printer despite the PSU being completely flipped off at the back! This is obviously strange behavior and not ideal for a device that is outside of it’s warranty period.

So I’m not sure how to proceed here. Firstly, what type of issue would cause this device to trigger a circuit breaker even when the PSU is turned off? Secondly, is there some way to fix this device that isn’t a major PITA? Has anyone else experienced this as well?

    If it’s not a GFCI or AFCI protected circuit then it has to be overcurrent or a bad breaker (they do stop being able to hold over time).

    For overcurrent, something isn’t right with your PSU and it’s drawing more than 15 amps or 20 amps if yours is in the kitchen.

    For a bad breaker, put your printer on a different circuit and see if it continues to trip. If not, swap the offending breaker out. Pretty safe to do yourself if you don’t touch the bus bar behind the breakers (otherwise it WILL kill you).
