Creality Printer Spaghetti Due to Bed Adhesion Loss

Verify this cause by inspecting the bottom surface of the failed print. If the base is smooth, curled, or shows signs of incomplete contact with the build plate, adhesion loss is the primary factor. Check for fingerprints or oily residue on the plate surface and ensure the first layer squish is sufficient by attempting to slide a piece of paper between the nozzle and bed at all four corners.
