Use may selectively perform any one or several steps, but the three steps from left to right must be

performed in order. The step(s) not required may be skipped by clicking the “Skip” button under such

step(s).

After different operations, the following table will guide user to selectively perform the step(s) among

three.

6.2.1 Auto 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. Firstly, carry out the leveling sensor triggering test. Heat the nozzle. After heating, it will prompt on

the screen to uplift the left nozzle with scraper knife. After the test is passed, Triggering

succeeded will be displayed on the screen. Click the “Next” button;

3. Calibration of the triggering distance of leveling sensor. Clean the nozzle and printing buildplate,

and then place the filler gauge (in 0.2mm thick) between the nozzle and the printing buildplate

glass. Click the "Z↑" / "Z↓" button to tune the up/down going of Z axis, so as to make the distance

between the nozzle and the buildplate glass just fits the insertion of filler gauge;

4. Take out the filler gauge, and click the “Calibrate” button. Z axis buildplate glass firstly goes up to

touch the nozzle, triggering the leveling sensor, and then goes down. Then click the “Next” button;

5. It will prompt on the screen to clean the printing buildplate. If the cleaning has been completed,

click “Autolevel” button to prepare to enter the formal execution of auto leveling;

6. The printing buildplate and chamber will be preheated first. After they reach the preset

temperature, the nozzle will be preheated. Finally the auto leveling will be executed. During the

auto leveling, the nozzle will detect 3 points on the buildplate. After completion, it will prompt on

the screen that the auto leveling is succeeded. It also will prompt to clean up the chamber. If the

cleaning has been completed, click "Finish" button. The buildplate will go down to the bottom of

the chamber and return. The auto leveling is so finished.

In following cases, please give up the auto leveling, and select manual leveling, of which the manual

leveling is in higher accuracy.

(1) The leveling sensor cannot be triggered or the triggering fails;

(2) The left nozzle used for auto leveling cannot rebound or the rebound is not smooth;

(3) The auto leveling fails;
