Tuning the Optics (Continued)
Adjusting the Mirrors:
An easy method for identifying exactly where the laser beam hits the mirror is to
place a piece of masking tape over the mirror, as shown in Figure 27a. Use the
least adhesive tape you can find (painters tape or masking tape, something that
will not leave residue).Next, use the “Pulse” button located on the LED Control
Panel to quickly emit a laser beam. The laser beam will quickly burn through
the tape leaving its mark as shown in Figure 27b.

⚠Please use caution, this is EXTREMELY DANGEROUS if done incorrectly.
If the laser is off-target of the mirror, the laser beam will shoot into the room
and hit someone or something. Pay very close attention when doing this test!
The laser beam has no color and cannot be seen, the red color you see is
from the red dot pointer, this is used as a guide for the naked eye of the
direction the laser beam is traveling.

Mirror Brackets:
The mirror bracket works as much like the tube bracket with additional
fine screws for micro adjustments. You will most- likely not need to use
the macro-adjustments for vertical or horizontal corrections, just the
micro screws for fine tuning.
An illustration of the mirror bracket in Figure 27c shows the fine
adjustment screws. Again, use caution and only adjust when the
machine is off. If you find that there is no burn mark on the tape
after a pulse test, make a large target with a piece of cardboard to
see where the laser beam is pointing. Then, use the micro adjustment
screws on the mirror bracket to bring the beam to the center of the mirror.
One, two or all three mirrors may have to be adjusted. Figure 27c Mirror Brack
Fine Adjustment/
Micro adjustments
For Example: If after firing a test shot no burn hole shows up on the tape, make
a large target with a piece of cardboard to see where laser mirror #1 is pointed.
Using just the fine adjustment screws, you should be able to bring the beam right
to the center of mirror #2. After tuning mirror #1 to hit mirror #2 perfectly, adjust
mirror #2 to hit the laser head dead center. Use the same masking tape technique to
adjust all the mirrors, and the tune-up will be done in little time.
Replacing the Lens
Lenses are one of the few parts of the laser that will need regular maintenance and cleaning. Cleaning the
lens is simple when done often but can become difficult or not possible when rarely done.
✎Note: The cleanliness of your lens can greatly impact the cuts and engravings that you are trying
toaccomplish with your laser. If the lens is obstructed with scratches or a film of char, it will not produce a
good quality engraving or cut.
