Found the machine halted, saying power had failed. Started a recovery but it made a total mess. 13 hrs wasted.
Was printing from USB.
The mess is on the part in the low right side of the pic. Best I can do for now, I’m not physically there.
It looked like it was restarting ok, it re-homed and came down on top of the messed part, but then nothing it printed seems to have stuck. My first guess would be that it was a couple layers higher than it should be.
So what can I send to help debug this, and what size UPS do you recommend so I can get back to production?
