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.
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.
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 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
I’m having the same issue, and I’ve tried all the recommendations, tightened belts, dried the filament, slowed it down, reconfigured (multiple times), even tried resetting to factory settings. I’ve only had it for 6 months, started having issues 2 days after the 3 month warranty ended and I swear this is the last Creality I will ever purchase.
i had this issue, and currently working on a fix, but what happened was after i had stop the print 7h23m when i saw the layer shifted i check the temp on the bottom plate with a thermal temp gauge read 56C. after a few min cooling down then retracted the filament, unplug the cord and turned it on its back, took off the feet and bottom plate and found out both vents were blowing in and no air circulation so i made up a temp fan holder for the mcu , and added a foot riser to the feet and reattached them without the bottom plate stood it back up and rerun the part again, after its 7h23m run it came out fine no layer shifting, i was running ASA so during the print temp was around 34c to 38c on the mcu and the psu was 36c to 38c, so my issue was over heated electronics… you would think they have better ventilation for this, so atm im making my own bottom plate…
Did you ever find a fix? I have this same problem on my K1C, started after I installed the CFS modifications. I’ve found a fix though, not a good one but in device details using Creality print if I change the print speed to “Stable 50%” it fixes it won’t happen. It seem that only the larger prints have the problem so I’ve started using the stable print speed with all my larger prints. It does take longer for the print, but not twice the time so thats come consolation. If you try this, please note that you have to set the speed to the lower settings AFTER the actual printing has started. If you change the speed shortly after sending the print, while its still warming, etc. then at some point it always changes the speed back to 100% standard speed when the actual printing begins. I need to send something to Creality about that and suggest they fix it somehow.
After working through all the documented problem solving steps, I have begun to suspect “chain droop” where the chain hits the case on the left side of the printer. I’m trying to figure out a simple way to determine if that’s what causes the layer shifts.
The chain doesn’t hit the lid, it is hitting on left side just below the lid. I don’t disagree with you about firmware, but I have absolutely no way to identify anything in firmware as a potential cause. I can only hope that the tech team is looking into the cause for these layer shifts, as it sure seams that a lot of K1 series users are having a problem with it. I’m just trying to find simple changes I might be able to make myself to stop whatever is happening when the layer shifts happen. I pulled the PTFE tube out of the chain, and printed some clips that attach the tube over the chain. The tube actually helps hold the chain higher, but it’s not enough to ensure the chain doesn’t crash the side of the case. After manipulating the print head manually, I am beginning to think the chain is too long and could easily remove two or three links however I’m not sure what the control wiring that runs through the chain would not become a problem with fewer links. Again, just looking at what I can do to maybe stop the layer shifts. I surely welcome any hints, tips, advice or solutions anyone else could and would share about this problem.
