Layer shift
I have recently ran into a problem with random layer shifting. I did not manage to spot why it happens.
Sometimes it is just one layer and the print continues s usual, just shifted.
Sometimes it seems like the printer is constantly walking sideways for couple of layers and that stabilizing again. Yesterday, I saw the process and could not determine why it is happening, not rough sounds, no grinding or unusual sounds whatsoever. I have checked the tension and it seemed fine. Today I will check the grub screws once again, but they seems fine too. The machine has been running for a long time now since I have build it during pandemic. Maybe I could swap the motor for one on the Z axis? I am running active cooling on motherboard and drivers (large Noctua fan), as well as passive heatsinks on the XY motors. I am printing around 200mm/s with PLA and default accel. I have figured that it tends to happen around 3 hours of printing.
