SV04 Bed Leveling Guide
1. Inspect the right extruder at first.
- Loose the 4 screws on both sides with H1.5 Allen screwdriver (Just loose, don't unscrew completely. If you do not know what is the appropriate condition you can tighten it first, and then loosen it for 1~2 turns to make sure the right side extruder can be adjustable up and down freely)
- Rotate the black leveling knob on the top of right extruder to check if the slide board can be adjusted to the top or the bottom. (If the slide board cannot be adjusted to the top or the bottom, please adjust according to SV04 Right Extruder Knob Adjustment Guide. You cannot do the next step until the slide board can be adjusted to the top or the bottom.)
* The top and the bottom position refer to the pic on the left.
* If the position can be reached please adjust the slide board of the right side extruder to the middle.
2. Stay in Step 1 condition(the whole slide board can be moved up and down to the end), tighten 4 leveling nuts under the heated bed and then screw back 1~2 turns clockwise.

4. After auto home, click Auto Z-align and wait the printer to auto leveling X axis.
5. Click AUX leveling to leveling the four corners.
6. Put a piece of A4 paper on the heated bed.
e.g. If you click 2 on the screen, please put the paper on position 2 of heated bed at first.
7. Keep the A4 paper back and forth continuously, and rotate the leveling nuts under the heated bed to adjust the distance between the nozzle and the heated bed.
* When you keep the A4 paper back and forth,the nozzle would leave scratches on the paper, but the paper can still be removed, that indicates the distance between the nozzle and the hot bed is appropriate.
* All of 4 corners should be adjusted. It is recommended that you adjust in diagonal order from 2 to 4, from 3 to 5 (numbers corresponding positions on the heated bed, refer to Step 6)
* Four corners are a group. It is recommended to repeat adjustment 2~3 times/group, because when you adjust one corner, the rest of corners would be also adjusted slightly.
8. Click the number 2 nozzle icon on the screen after completing adjustment of number 1 nozzle.
9. Repeat the paper measurement method from step 7, rotate the top knob on the right extruder to adjust the distance between the nozzle and the heated bed.
