6. Laser focus adjustment
The effect of engraving or cutting largely depends on whether the laser is focused or not. Most of the existing laser engraving
machines on the market use zoom lasers. It is necessary to turn the focus nut while staring at the laser spot to observe whether
the laser is focused. Staring at the laser spot for a long time can hurt your eyes (even with goggles), and it is difficult to distinguish
small changes in focus, so it is difficult to find the best laser focus.
In order to solve this problem, we abandoned the traditional zoom laser and installed a fixed-focus laser on our engraving
machine. The focus is at the thickness of a fixed-focus film of the laser, and the fixed-focus film is attached in the package. When
using, only need to adjust the laser.
The following is the specific operation:
A. Move the laser head to the object to be engraved or cut.
B. Place a fixed focus film on the object to be engraved or cut.
