Strange shifting behavior--any ideas?
This is happening printing ABS on my mk3s, and has happened a couple of times in exactly this way--with a layer shift very near to the beginning of the print. I might have thought the model was shifting on the bed, but that's not it because I printed 3 parts at the same time and they all show this behavior.
I have no problems with PLA. Is it possible it's something specific to ABS/these prints, or am I looking at a belt issue?
are you getting any crashes?
Have a look at the LCD menu
if this happens again
