How to remove and put back the laser shield.
Use the focal gauge board to adjust focus (for the new hand).
When the laser shield of the laser module, the focal gauge board and the laser engraved object are attached to each other, the focusing is completed. Grasp the hole of the focal gauge board with your fingers, and drag the focal gauge board out.
Use the aluminum plate to adjust focus (for the adept).
Slide up and down to adjust the focus, find the position of the smallest spot, flashing spots appear as shown in the figure.
After focusing, put the laser shield back under the laser module.
