Right in the middle of an absolutely massive print this x axis shift occurred. MK4 printer. Printer ran a calibration just prior to print. Once my tears dry up, and I buy some more filament, how do I prevent this from happening again when I retry this?

    Had slipping issues for taller prints as well. Brought the print speed way way down and it seemed to work.

      It's a 48h print with variable print speed. I wonder if the variable speed threw it off somehow. I will check my belt tension. Will be a little disappointed if that's already off since it's a fairly new printer. Will try the reprint without variable speed and maybe I'll simplify the design elements a bit.

        If belts are tensioned not too tight and not too loose;

        The next thing to look at is the drive gear on the x motor- if it’s a bit loose, it could slip.

        Another thing is the hotnend mount- if it’s Loose it can wiggle back and forth as it drags on the part.

        Then, finally; if none of those seem off; check the x motor itself for voltage and overheating.

        Belt tension should be checked regularly and definitely before printing on a new machine. It being new doesn't have anything to do with belt tension.

    Are all belts on the printer tightened properly? Did you print via Octoprint? Sometimes this may happen if there's a short network / WiFi issue. Can also happen with some brands of SD cards. So if you have another one available that might be worth a try.

    And can't you save your print by simply grinding off the superfluous filament? If parts are missing you might also add some glue or putty to fill the gaps. If visual appearance is important for your part you could also apply some spray paint or acrylic paint.

    Belts being too tight is just as much of a culprit as belts being too loose. Tension your X axis belt correctly.
