4 First print
4.1 Level the print bed
The first layer is key to a successfully printed model. The factory default setting is a little high in
order to avoid scratching the hotbed with the nozzle, so users need to adjust the distance
between nozzle and hotbed again. After the first-time bed leveling, users may need to level the
bed again in future.
 Rough leveling
Home the printer first (Prepare> Auto home), then it shows the option “Level corners” on the
LCD screen. Put a piece of A4 paper on the platform, click “Next corner”, the extruder head
moves counterclockwise from the bottom left corner to the four corners of the platform. See
picture (4-1, and 4-2).
(Picture 4-1)
(Picture 4-2)
When the extruder head moves to the left bottom, adjust the corresponding knob until the
distance between the nozzle and bed is about the thickness of a piece of paper (about
0.1-0.2mm). Slide the paper back and forth to see if you feel a slight resistance. If yes, it means
the leveling of this corner is finished and you can proceed to level the rest corners with the same
method. See picture (4-3).
