FAQ
Q1. The model can’t stick to the hot bed
Solution 1: The nozzle is too far from the heated bed, you can re-do the automatic leveling or continue to adjust the distance
between the nozzle and the heated bed after printing starts, until the first layer can be well pasted on the heated bed.
Solution 2: The surface of the hot bed is too dirty, preheat the hot bed to 60℃, and use a cotton cloth dipped in alcohol or water to
clean the surface of the hot bed.
Solution 3: The model is warped, and the "brim" mode is selected when slicing to prevent the model from warping during the
printing process.
Solution 4: Apply solid glue on the surface of the PEI platform.
Q2. Nozzle abnormality

and re-feed.
