Check the temperature setting before printing, PLA filaments have lower extrusion temperature;2. Check if the plate surface has been used for a long time, it is recommended to replace it with our new one to ensure an strong first layer adhesion;3. If the first layer has poor adhesion, it is recommended to re-level the print substrate to reduce the distance between the nozzle and the surface plate;4. If the effect is not good, it is recommended to try printing the draft before printing.
