CO2 Laser Alignment
CO2 laser alignment should be checked
periodically to ensure that the engraver is
operating at optimum peormance.
Complete this procedure if any of the
following behaviors are observed:
• Laser power appears weak in certain
areas of the table, especially when
moving from le to right in the
engraver
• The engraver is unable to eectively
cut through materials at or around the
recommended settings.
• Optics in the lens assembly fail
prematurely.
• If the engraver has been moved to a
new location.
Or if any of these components have been
replaced:
• Laser tube
• Mirror #1, #2, or #3
• X-axis assembly
• Red dot diode
CO2 Laser Safety
The laser assembly used in the Fusion Pro
CO2 engraver can cause serious and or
permanent injury if safety procedures are
not observed.
Do not fire the CO2 laser with any of the
engraver panels removed.
Do not place any part of your body in the
beam path while the laser is in operation.
Do not defeat the safety interlock system
in the engraver.
It is recommended that eye protection
such prescription eyeglasses, Lexan, or
other polycarbonate safety glasses be
worn by all those present for the duration
of the laser alignment procedure.

The CO2 laser alignment consists of three
(3) parts:
• Pre-alignment to ensure that the CO2
laser and red dot diode are coaxial.
• Cutting laser alignment.
• Perpendicular alignment
Pre-Alignment
1. Turn on the engraver, and let it
complete the startup process.
2. Install the laser alignment target over
the window optic on the le side of
the lens carriage and place a piece of
masking tape over the target:
3. Press the Gear icon on the display to
enter the Settings menu:
4. Press the Alignment button to enter
the Alignment Mode menu:
The Alignment Mode menu allows you to
move the lens carriage to specific table
position and fire the laser without the
need to send a job to the engraver.
5. Ensure that the laser power is set to
10% and press the Activate button
once to fire the laser.
6. Look through the top door, or open the
top door if needed, and observe if the
laser marked the masking tape.
7. If the laser did not mark the tape,
close the top door and press and hold
the Activate button while observing
the masking tape on the alignment
target. As soon as you observe the
laser marking the tape, let go of the
Activate button.
In certain situations the CO2 laser
alignment may be very poor, preventing
you from getting a burn mark in position
4. If this is the case, attempt to get a burn
mark in position 1.
8. Once a burn mark is observed on
masking tape, press the Red Dot
Pointer button to turn on the red dot:

17000 - CO2 Laser Alignment

1. Inspect the location of the red dot in
relation to the burn mark le by the
laser.
If additional viewing space is needed to
observe the alignment target, the y-axis
bellows can be disconnected from the
x-axis assembly.
2. For an accurate alignment, both the
red dot and burn mark should appear
in the same exact location on the
tape.
3. If both the red dot and burn mark
appear in the same exact location on
the tape, move to the next section of
the alignment procedure.
At this point in the alignment procedure,
the goal is that the red dot and burn
mark are aligned with each other. The
position of the red dot and burn mark in
relation to the center of the alignment
target is not important.
4. If both the red dot and burn mark do
not appear in the same exact location
on the tape, remove the lower rear
panel of the engraver and locate the
red dot diode to the right side of the
laser tube:
Adjusting the Red Dot
1. Adjust the red dot so that it is
centered over the burn mark on the
masking tape made by the laser using
the three (3) Allen adjustment screws:
2. Once the red dot and burn mark
appear in the same exact spot, install
the lower rear panel of the engraver
and move to the Cutting Laser
Alignment procedure
Cutting Laser Alignment
It is very important that the laser and the
red dot are coaxial prior to beginning this
process. You will not be able to properly
align the laser if the red dot and the
cutting laser are not coaxial.
For alignment purposes, the table of the
engraver is separated into four (4)
quadrants or table positions. The
location of each quadrant or position is
determined by the relative distance from
the laser.

Table Positions
There are four (4) mirrors in the Fusion Pro
CO2-only engraver, all of which may need
to be adjusted while aligning the cutting
laser.
Each of the mirrors in the Fusion Pro
engraver are referenced by number in
this procedure and correspond to a
specific table location. When adjusting
a mirror, ensure that the correct one is
being adjusted for that specific table
location.

6. Once the red dot position is centered
on the alignment target, move the
carriage back to position 1.
7. If the red dot position is still centered
on the alignment target while the
lens carriage is in position 1, move to
Adjusting Mirror/Position 3.
8. If the red dot position is no longer
centered on the alignment target
while the lens carriage is in position 1
aer adjusting position 2, adjustments
to mirror/position 1 will need to be
made again.
9. Move between positions 1 and 2,
adjusting the respective mirror for
each position until the red dot is
centered on the alignment target at
both positions.
In some cases, this process can take
several back and forth movements be-
tween positions 1 and 2. Ensure that the
correct mirror is being adjusted for each
position.
Adjusting Mirror 3/Positions 3&4
1. Ensure that the red dot pointer is
activated.
2. In Alignment Mode, press Top Right to
move the lens carriage to the top right
corner (position 3) of the engraver.

using the three (3) Allen adjustment
screws located on the back of mirror 3:
Mirror 3 Adjustment Screw Guide
6. Once the red dot position is centered
on the alignment target, move the
carriage back to positions 1 and 2.
7. If the red dot position is still centered
on the alignment target while the lens
carriage is in positions 1 and 2, move
to the Perpendicular Alignment.
8. If the red dot position is no longer
centered on the alignment target
while the lens carriage is in positions
1 and or 2 aer making adjustments
to mirror/position 3, adjustments to
mirror/positions 1 or 2 will need to be
made again.
9. Move between positions 1, 2, and 3,
adjusting the respective mirror for
each position until the red dot is
centered on the alignment target at
all three positions.
In some cases, this process can take
several back and forth movements
between positions 1, 2, and 3. Ensure that
the correct mirror is being adjusted for
each position.
Perpendicular Alignment
Once the mirrors have been aligned, we
need to adjust for the perpendicularity of
the cut. By making these adjustments, we
can ensure that the vector cut is as close
to 90 degrees as possible.
This is a very important step for
customers who do a lot of cutting with
the machines.
Failure to verify the perpendicular
alignment can result in poor vector
peormance and premature failure of
the optics in the lens carriage.
1. Ensure that the red dot pointer is
activated.
2. Use the Focus menu to raise the table
up, stopping short of depressing the
autofocus plunger.
3. Remove the alignment target from
the lens carriage and place it on the
table, directly under the lens tube.
Move the target so the red dot is
centered on the alignment target.
Once here, place a piece of masking
tape over the target to ensure that it
does not move.
4. Using the Focus menu, lower the table
3-4” (75mm - 100mm).

18. Raise the table while watching the
location of the red dot. If the red
dot moves o of the center of the
alignment target, repeat this process,
until there red dot does not change
position when raising or lowering the
table.
