I recently had a similar problem in the middle of a print. it hit an end stop and grinded on the side, made a terrible noise.
It turned out to be one of the pullies on the short belt and axis bar got loose. I replaced the black setscrew with the silver ones that came in a little bag, and tightened it a LOT.
when, off try spinning the motor on the X and Y and see if it directly drives the print head, if there is slippage, your pully is loose. Tighten it and run it again.
For me, it was this pully on the left side.
Best of lucks.
Is the fan running and blowing air across the electronics?
Can you post a video please?
