Beam mode quality becomes poor

1 Screw loose

The beam shaping mirror (M100/M150 and M2-100/M2-150 laser sources) is displaced or rotated due to screw looseness. Generally, the reasons are as follows:

1. Disassemble without permission.
2. The shaping mirror is impacted.
3. Hold the laser shaping barrel in one’s hand while moving the laser source.

2 Manually rotate the dimming screw

The effect of beam spot becomes poor, the power drops as well.
