Please check whether the laser beam is all vertical to the working table’s center and four corners. If yes, please continue to check step two of beam verticality below.

If not all vertical, please adjust the laser beam path (directly adjust the third reflective mirror). Please refer to below video to learn how to check the verticality of laser beam. Please go to step 4 and step 5 of above video directly or you can skip to timing at 03:24 of the video

1) When the laser head move to four corners of the working table, check if the laser beam lasers to the same position of the third reflective mirror.

2) When the laser head moves to four corners of the working table, check if the laser beam can vertically go through the acrylic.

Make sure the laser path can meet above two requirements. If not, please adjust the verticality as following instructions (for 3rd reflective mirror)

                                                               3rd mirror mount

Adjust screw A: Loosen the nut and rotate clockwise, then the laser beam will moves left; if you rotate counter-clockwise, the laser beam will moves right.

Adjust Screw B: Loosen the nut firstly. If rotate clockwise, the laser beam will moves upward; if rotate counter-clockwise, the laser beam moves backward.

Adjust screw C: Loosen the nut. If rotate clockwise, the laser beam will moves forward and right; if rotate counter-clockwise, the laser beam moves backward and left.

White screws D: Please loosen these three white screws before adjusting Screw A/B/C. After finish, tighten these three white screws (and lock all nuts of screws)

Verticality Step 1:

Adjust Screw A/B/C so as to change the angle of the third reflective mirror. If the laser beam comes out from the bottom center of the laser head, it proves that third mirror is in right 45°. 

Make sure the laser beam comes out from bottom center of laser head, like below:

Verticality Step 2:

Pulse a laser beam on 10mm acrylic, check if the line is vertical or not
