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?
No one has said it yet, but the most common cause of a breaker being thrown is an overload or a short. It looks like you’ve determined it isn’t an overload since it happens when the device isn’t turned on. That indicates that you may have a short. The two likely places are the PSU (since it’s supposed to be turned off) and the cord (since the PSU wouldn’t matter). If the cord is replaceable, I’d try that first. After the cord I’d see about replacing the PSU. Hopefully it’s a standard part and not something you have to buy from Ender if they still carry it. Another thing to check is if it’s the outlet. If you try it on a different outlet and get the same problem, it is likely the device.
The cable is an interesting point, as I haven’t tried a different cable. Since there’s a non-zero chance that it could be responsible, I’ll try switching it next time I plug it in. I suppose the cable they shipped me could be bad.
