About this video tutorial

• This video tutorial aims to provide step-by-step instructions on how to test for optical path deviation and calibrate it accordingly.

💡Rationale for optical path calibration
1. Check for Deviation: Detect whether the laser path through the third optical path hole has deviated. If there is no deviation, calibration is not needed. If there is a deviation, calibrate the machine’s optical path.
2. First Optical Path Hole: If the laser is not detected through the third optical path hole, check the laser tube at the first optical path hole to ensure the tube is functioning correctly.
3. Second Optical Path Hole: If the laser passes through the first optical path hole correctly, check and calibrate the laser position at the second optical path hole.
4. Third Optical Path Hole: After calibrating the laser position at the second optical path hole, check and calibrate the laser position at the third optical path hole.
