[ Manual N2&N2 Plus - How to Level the Heating Bed - V1.0 ]
#Warning: If you want to level your heating bed by yourself, please carefully follow this instruction. Incorrectly adjusting your printer may damage the whole heating bed.
1.If necessary, home the Z-axis and adjust your Z-offset. Use a feeler gauge to check the resistance between the bed and the nozzle. We recommend using the middle of the bed as the reference position.
With a good Z-offset there should be a small amount of resistance when passing the feeler gauge between the nozzle and bed. The print head should not lift when the feeler gauge is slid between the two.
Depending on the model, there are either 13 or 9 sets of screws. Please check to determine which model is being adjusted.
2.Disable the motors from the Utility section on the touch screen. Move the print head to each point shown. Use the feeler gauge to check if there is the same amount of resistance as at the center point.
If resistance is greater, or the feeler gauge cannot be slid between the nozzle and the bed, and then the bed will need to be lowered at that point.
If the resistance is lower, or now the resistance cannot be felt, the bed will need to be raised at that point.
3.To raise a point in the heat bed, loosen the nut in the middle of that point by two turns.
4.To raise the heat bed by using a 2.5mm hex wrench to turn the nylon tip screw CLOCKWISE. Use a feeler gauge between the nozzle and the plate to check the gap in between them. After the bed rises to the desired height, lock the screws in the middle by tightening the M3 nut. After the middle screw is tightened, turn the nylon tip screw to normal tightness (about 20Kgf.cm).
5.To lower the bed by rotating the nylon tip screws COUNTERCLOCKWISE. Keep the screws at relatively the same height, and then tighten the nuts.
6.Perform the same procedure to each point when necessary.
7.Redo Step 1 to check if all points are at the same height. If not, please adjust it accordingly. If yes, please make sure that all screws are tight.
