While performing the laser alignment all persons present in the room
during the performance of this procedure must be equipped with adequate
eye protection (Lexan safety glasses, eyeglasses or goggles), and that no
one looks or places any part of his or her body into the path of the laser
beam.
This procedure requires that the laser be operated with the
engraver’s door safety interlocks defeated or with protective covers
removed. While the laser power levels are reduced from those of normal
operation, they are sufficient to inflict eye injury or burns.

Before you start…
Direction
Many of the instructions provided in this procedure will have a direction given,
such as left hand side or right hand side. Unless otherwise stated, these are all provided
as though you were facing the machine from the front.
Table Positions
For the following procedures the table will be broken into four (4) positions. Each
position is identified by its relative distance to the laser source and corresponds with the
mirror to adjust for that position.

Mirrors
The three (3) adjustment mirrors used for alignment are on the left side of the
engraver. The mirror numbers correspond directly with the positions on in the bed; for
example, if the lens carriage is in Position #1 than you will only adjust Mirror #1.
Jogging the lens carriage
When moving the lens carriage on the engraver you will be use the “Jog” mode
on the keyboard. When asked to move the lens carriage into a position you only need to
move it as far as practical. Move the carriage as far into the requested corner as you
can while maintaining the ability to see the red dot pointer on the alignment target.
Laser Jog Power
Set the lasers Jog Power to a level that is high enough to mark the tape but not
so high as to burn a large hole in the tape and target. Setting the lasers “Jog” power is
detailed in your machines owner’s manual. 10% is a good starting point.

please move on to procedure B. For all other alignments this procedure must be
completed.
Step 1: Remove rear panel
Locate and remove the eight (8) 5/32” Allen screws which secure the lower rear
panel to the engraver. Remove the panel from the engraver.

over the alignment target represents a piece of masking tape placed on the alignment
target.
Step 4: Make burn

Step 5: Make burn
Use the Joystick on the engraver’s keypad to move the Lens Carriage to Position
4 on the bed.
Step 6: Make burn
To fire the laser in Jog mode, Depress the Fire Laser key (indicated by Arrow in
picture below) and move the Joy stick to the left or the right. This will need to be done
fairly quickly as it takes little power to burn the masking tape.
