The printout shifts by 10mm along the x-axis in the middel of the printout  

RE: The printout shifts by 10mm along the x-axis in the middel of the printout

Bearings are probably seizing on the rods - but may be mechanical interference that high up. Add the fact the offset started down near layer one according to the filament extrusions on the masking tape.

Then again, with so little to go on, it could have been a cat.

What profile are you printing that with? your image doesn't look like its setup for the standard Prusa bed and it doesn't look like the G-code viewer.

Was this sliced for some other printer?

RE: The printout shifts by 10mm along the x-axis in the middel of the printout

Maybe you're in on something. I thought I was using the MK3 profile, but the printer gives me a warning that I am printing with another printer.. 

RE: The printout shifts by 10mm along the x-axis in the middel of the printout

I'd like to know if the print was removed from the bed then returned for the photo op. Or if it it was in that offset condition when the top shifted back.  In any case, a stall happened, either once, or twice. And my guess is the extruder case is too tight on the bearings. Or a cat.

Hello, it was not removed from the bed. If you see closely it went wrong alleredy at the first layer, there is an offset between the first layer, and the support.

I'm reprinting with the standard profile for prusa mk3+ for PETG. Looks better. Will post the result 🙂

Hopefully, you are successful.  Strange things happen during prints.  Sometimes are they are repeated.

The two offsets indicate bearing seizure. Add a drop or two of light machine oil on the two X-axis rods, either side of the extruder, but within range the the print moves so the oil works into the bearings. 3-in-1 or sewing machine oil or razor oil work well as a temporary fix.

Looks like a layer shift in the first layers and maybe a crash detected later on in the print. A crash detection will home the extruder and than it will start at the right place according to the gcode. But that will wrong because of the earlier shift.

Like Tim said, you have a mechanical problem somewhere.

RE: The printout shifts by 10mm along the x-axis in the middel of the printout

And a crash will not recover as cleanly as expected because once a crash happens, the printer has lost all knowledge of where 0,0,0 is. One or more of those zeros now has an undertermined offset due to the motor stalling and losing counts/steps.

Success! I’m not sure what did the trick, but I switched to Prusa profile for PETG. I will oil the bearings. Thanks!

Sometimes we don't know why we are successful.  Just accept it.

Very nice Print.

if you're having to use tape to get adhesion, you might want to look into that.  I made that mistake early on and it ended up my zOffset was way too high and I had change extrusion width and other things to try to get adhesion.  With PETG and a clean(dawn plus a good scrub) and then windex original as a release agent, you shouldn't get good adhession without having to have tape/glue.    For small parts with less contact with build plate I'll still use some glue or layerneer or magigoo just to ensure that first layer doesn't come loose.
