3. The nozzle part and heated bed can produce high temperature when the printer is
working ,so do not touch them by hand to avoid being scalded.
4. Before the automatic leveling, prepare the leveling sensor and an A4 paper and clean
the nozzle, insert the leveling line; After the Autoleveling , remove the
leveling sensor, then adjust Z0.
5. In the event of an emergency, please turn off the power immediately and contact our

Common Problems
B
Use Part
B-5
1. What to do after automatic leveling?
3. What is the printing temperature of the common materials?
4. The first layer can not normally stick to the platform.
5. The nozzle block
2.When the nozzle is too close or too far away from the hot bed after leveling?
Remove the leveling sensor, then adjust Z0,install the filament, then preheat the nozzle to 210 ° C,
preheat the hot bed to 60 ° C, feed filament and start printing.
Click once to move the nozzle 0.1, Z+ nozzle moves up, Z-head moves downwards, the software automatically saves
the value after clicking, and the value is saved until it is leveled again.
①. The nozzle is too far away from the hot bed，please refer to the nozzle is too close or too far
away from the hot bed
②. Select the Brim when attaching platform to slice，increasing the value of the line according
to your neded,Set hot bed temperature to 65°
