Print malfunction

Prints were turning out great then for unknown reason this started happening
Should be cylinder shaped and for some reason bed moves forward and print continues

Is it the same file that was sliced before? Or did you slice it again? I feel like it might be a slicer issue. try re doing that and see if it helps. Make sure nothing is snagging the filament. I could easily be the extruder or something else but simple things first

Has it only happened once or is doing it constantly. I have had a print do something like that and then repeated the print and it was fine. Sometimes the code gets corrupted.

Found out a bearing was seized causing the table movement to be restricted. Freed up bearings and works as new again
