Massive Layer Shift on MK4
Hi everyone,
I have an issue with a my most recent prints. I have tried printing it about 8 times and every time have a massive layer shift. Not just a tiny shift due to an issue with the belt. I'm talking of a 1-2cm shift (see images). Previously the printer printed fine.
I have tried many things to resolve the issue but without any success:
- rechecked x+y belt tension
- recalibrated x+y axis
- cleaned nozzle
- re-sliced model
- used different infill patterns
- reduced printer speed to 50%
I'd appreciate any hint or tips, as I don't know what the actual problem could be. I don't think it is a physical shift of the print, as the printing plate is still well in position after failure.
My printer also has a MMU.
Thanks a lot and best regards,
Phil

Unfortunately, I too have exactly the same problem.
No problems at all when running as a straight MK4, but after I added the MMU3 and updated the firmware, I get a massive layer shift, always in the X axis. It happens about one in every 3 or 4 prints.
I am running prusa3d_fw_MK4_MK4S_MK39_MK39S_6_1_3.bbf.
The image shows 2 failed attempts at printing these 2 pieces.

I also have this problem. I have the problem on multiple prints and on multiple MK4 printers and on my XL (no MMUs). I am wondering if it is the memory sticks, the bgcode file format, or my mac. Keen to hear if anyone has solved this problem.

Yes, I have the same issue, mostly with boxes. It is a recent occurrence, only the last month or two. Models that printed with no issue before, are now having issues.
With the boxes, at best, I now have a seam at the top layer of the bottom. At worst, a huge offset.
To be honest, I don't think there is anything that can be done on our end until Prusa releases a fix.
