The problem went away. I tried moving it to a corner and it worked, but also two more prints since then back in the center also worked.

I guess I'll never know what it was. I'm going to do a thorough maintenance anyway.

Odd that it always happens at the same z level. Try regenerating the g code. Please let me know what the final solution was.

See step 28 here:

Then the same for X.

Cheerio,

I don't see how that could explain the weird symptoms but thanks. I'll definitely check them out.

P.S. I call them set screws.

@mchahn

It would appear you have a loose screw, a Grub screw some call it. I call it an Allen screw, it's the one that tightens on the arbor of the stepper motor. check those first.

They are on the X and Y axis.

I'm having trouble with print shifts on my MK3S+. I've tried three times to print the same gcode. See the attached image. The reason I call it a mystery is because it happens sometimes in X and sometimes in Y but always at the same Z height. Also I printed a tower and there was no shift.

I'd think it was something on a guide rail or belt at one position but the inconsistency in X and Y rules that out. And I don't see how a problem with the Z screws could cause lateral shifts. I'm trying to print it now at a different bed location but I doubt that will help. Does anyone have any idea what could cause this?
