Question 5:................................................................................................................................ 38
When the machine is leveling, the nozzle moves to the left, it can be leveled normally. When
the nozzle moves to the right, it is found that the distance between the nozzle and the
heated bed are very far or very close. If the spring is adjusted to the extreme position, it still
cannot be leveled. What should I do?...................................................................................... 38
Question 6: After the machine heats up, the filament is discharged normally. However, when
the printing is performed for the first time, the curling occurs on the platform. After printing
several layers, the filaments get out of the platform. What can I do...................................... 39
