Note: When installing, please make sure that the X-axis beam is parallel to the front and
rear beam profiles. You can use the rectangle on the scale for auxiliary adjustment.
Without parallelism, the Y-axis will be difficult to move and affect the engraving effect.
4. Adjust the X-axis beam to make sure it is parallel with the front
and back frame.
5. Tighten the X-axis synchronous belt.
Tighten the thumb screw
Note：
Synchronous belt needs to be tightened, otherwise it
may cause the problem of engraving misalignment.

Note: Install the laser module
at a vertical angle (90°).
Note:
① It is the most appropriate position to feel a
little friction between the POM wheel and the profile
when rotating the POM wheel.
② If the wheel rotates in the air and does not fit
the profile, the eccentric nut can be adjusted
clockwise from the direction of the screw head with
an open-end wrench.
