Printing position sudden shift

Hi all

I’ve been struggling to print this file and this has occurred on some other prints too. The printer seems to suddenly go way out of position and ruins the print. Things I’ve tried on my Creality KC1 printer so far is to tighten the belts, update to most recent slicer Creality software available (which when i did initially seemed to fix the problem) but now its back.

Not every print is going wrong but this print has now failed 3 times at around the same point.

Any ideas folks where i should look next???

Thanks in advance

I’m having the same trouble trying to print a gridfinity case that is nearly bed-max size. It’s failed 3 times, with 2 different filaments, at about the same layer, using Creality Print 5 and 6, and it’s driving me crazy. The first two times, I heard a loud CRACK sound when the layer shift happened.

Same thing in my case. Any clue how to solve this?

my printer is the K1 Speedy and i have the same problem and it is only 3 weeks old ??

I’ve had this problem with 2 different prints. The first one I resent the model from the slicer and it printed OK. But, I don’t think that was the answer.
The 2nd time I finally got it to work by doing 2 adjustments. I loosen the drive belt screws to allow the belt to auto tension. Retighten all screw and I think this would have worked (procedure on internet). My thoughts are the print head jump the track because the screw(s) were loose. Just to be sure that I did everything I could, I also adjusted all the speed setting to 50% of default speeds for this model so the movement wasn’t has violent. The print time for my model went from 4 hours to 5 hrs, but it printed 4 times with no problems.
I think my issue was some loose screws. I hope this helps.

I also got the same issue. it always happen with parts that are very big. Do you think it could be the slicer that accelerate too quickly and it slip?

I am currently printing entire bed of small gears and it they have all shifted right after the first few layers. This is a first time seeing this. Not good
