6.1.1 Manual leveling

1. Click the “Leveling” icon. A prompt dialog box will be popped up, prompting to clean the printing

buildplate and chamber to prevent interference with the leveling operation. If the cleaning has

been completed, click "OK" button to formally enter the manual leveling operation;

2. Heat the nozzle first. Clear the residual material on the nozzle with tweezers or brush after the

heating. Screw down the 4 rotary knobs under the printing buildplate to prevent the nozzle from

colliding with the glass plate during the leveling. Click the “Next” button last;

3. According to the prompts on screen, rotate the rotary knobs under the printing buildplate with

hand respectively, and meanwhile measure the distance between the nozzle and the buildplate

glass plate with filler gauge (in 0.2mm thick). Pull the filler gauge back and forth and adjust the

filler gauge to just pass through the distance, and then click the “Next” button;

4. After the 4 points on the buildplate are adjusted for the first time, “Redo2-5”button will be

displayed on screen. Click this button to repeat the leveling;

5. After the completion of the second manual leveling, “Finish” button will be popped up on screen.

Click this button to lower the buildplate to the bottom of Z axis, and then return. The manual

leveling is finished.

NOTE:

• Before the leveling, press the four magnet blocks with hand to make them be fully seated in the

magnet holes of the hot bed, so as to exclude the gaps between them;

• The residual material on nozzle cusp should be cleared before leveling;

• Before leveling, the printing buildplate should be cleaned up without any printed piece, large piece

of glue or other foreign matter remained on it;

• Before leveling, the chamber should be cleaned up to prevent a collision when the buildplate is

being lowered;

• Be careful to prevent scald in operations as the nozzle is in high temperature during the leveling.

6.1.2 Z calibration

1. Click “Zcalibrate”icon to pop up a prompt dialog box, prompting to clean up the printing buildplate.

If the cleaning has been completed, click "OK" to formally enter the Z calibration operation;

2. Calibrate the left nozzle first. According to the instructions on screen, place the filler gauge

between the nozzle and the glass buildplate, make coarse tuning with the "Z↑0.05" / "Z↓0.05"
