I have a problem with my Creality Ender 3 printer. When I start printing, the first few levels go fine. But then the extruder starts slowly moving in the wrong direction and after a few minutes the extruder is completely out of its original position so the whole printing is ruined.
I tried to start again but it is doing the same thing all the time. Calibration and modification of the bed does not help. Can you advise me on how to fix this situation?
