Prints were turning out great then for unknown reason this started happening
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
