• If the filaments do not stick to the print platform:
• Please check if the nozzle is far away from the print plate, you can adjust the platform upward by offset adjusting function.
• Because of the different ambient temperatures in different regions, the temperature of the heat bed can be increased appropriately to increase the adhesion of the filaments.
