Check whether the light spot is normal.

Under the normal working condition of the laser, move the third reflector to a distance of 1500mm from the light exit.

Place the acrylic plate in front of the third mirror, perpendicular to the laser beam.

Press the button briefly multiple times and observe the shape of the light spot. Under normal conditions, the spot is a solid circle. If the spot is abnormal, send the test video to the after-sales staff.

Suggestion for the best setting: the light spot of the third reflector should be at the same point in the four corners of the workbench.
