¶ Phenomenon:
¶ During automatic leveling, the leveling module hits the heating bed or the nozzle does not lift after contacting the heating bed, dragging and rubbing on the heating bed
¶ Solution:
¶ 1. Check whether the leveling module is installed correctly
¶ 2. Re-flash the motherboard firmware and automatically level again.
¶ 3. If the leveling stops after the heated bed rubs for a certain distance, it is usually caused by belt stretching. Please check whether the three belts are deformed or stretched. If the belts are deformed, replace them with new ones.
