A: This problem occurs mainly because the heat is not dissipated quickly enough, after the high temperature consumables are extruded from the nozzle, they are not cooled down quickly enough, and will change their shape in the process of cooling down slowly. To solve this problem, you can refer to the "Object Overheating Problem" mentioned earlier. If this problem occurs at the very beginning of the printing process, you can refer to the "First Layer Off Platform Problem" mentioned earlier.
