The fourth step: Optical path adjustment between the second and the third reflecting mirror.
First, move the laser head to the left of the X axis, put the test paper in front ofthe hole of the laser
head, press "Pulse/Run" key slightly and check the spot. Then move the laser head to the right of the
X axis, press "Pulse/Run" again, and check whether the two spots coincide with each other, if coincide
and the two spots are within the hole of the laser head, then optical path is correct. If not, please adjust
the screws on the second mirror holder to reach above standard
（
Attention
：
the principle of optical path
adjustment is the same between mirror 1 and 2, 2 and 3
）
. Then adjust the location of second mirror
holder (Y-axis direction) and the height of the laser tube, to make sure the spots are within the hole of
laser head (center is better). Below Figure:
