About this guide

• As a result of replacing the mirror holder (Pic 1), there may be a significant deviation in the level 2 laser path.
• To avoid machine damage from laser offsets, it is recommended to recalibrate the laser path following the replacement.
• Follow the steps below to verify any deviation in the laser path and learn how to calibrate it if necessary.

How to do it

#1 Check the second-level laser mirror

Check its installation:

• Position the mirror's reflective surface inward, displaying alphanumeric characters outwardly.
• The reflector notch should snap right into the lower left screw on the holder as shown in Pic 2.

Check the gap:

• Examine the 1 mm gap (highlighted in red in Pic 3) between the adjustment plate and the fixing plate (highlighted in green in Pic 3).
• If the two plates are too tight, loosen the fastening screws by turning them counterclockwise. Afterward, increase the gap by turning the adjustment screw clockwise until the gap measures roughly 1 mm.

Make sure that both of these checks are met before testing the level 2 laser path.

#2 Level 2 laser path test and calibration

• Please refer to the 5:07 mark in the video below for testing and calibrating the level 2 laser path.
• Specific timestamps for the test and calibration:
  • Level 2 laser path test: 5:07 - 6:08
  • Level 2 laser path calibration: 6:09 - 8:19
