Mirror Alignment Procedure
Steps:
1. Gantry Alignment
2. Preparation
3. Verify centering and no clipping at
Mirror #1
4. Align Axis A-B (Y-Axis) using red dot
generated by the Alignment Laser
(fig. 36).
5. Align Axis B-C (X-axis)
6. Centering on focus lens. (Z-axis)
Materials needed:
• Thermal paper (supplied). When supply
is exhausted, purchase adhesive
backed thermal paper.
• 2.5mm hex wrench (supplied).
Step 1: Gantry Alignment
The first task of mirror alignment is to
ensure that the Gantry is perpendicular
to the Y axis rails. Often misalignment
occurs when the Gantry is bumped or
moved while the motors are in a locked
state.
1. To verify alignment, push the Gantry all
the way forward until it contacts the
front stops and backward until it
contacts the rear stops.
2. The Gantry should touch the stops at
the same time on both the left and
right side. If it touches evenly, move to
Step 2: Preparation.
3. If the Gantry does not touch both
sides, the motor connector under the
tube guard needs to be loosened.
a. Do this by removing 3 screws of the
Tube Guard and lifting the Tube
Guard up off of the posts. (see Tube
Guard Removal, page 70)
b. Loosen the screw on the left side of
the motor connector.
c. Shift the Gantry tight against the
front stops and hold evenly.
d. Tighten the screw on the motor
connector while holding the Gantry.
e. Replace the Tube Guard using great
care not to damage any wires or the
Laser Tube.
4. Rerun the four corners mirror
alignment test to see if further
alignment is necessary.
Step 2: Preparation
Prepare your tools and workspace.
1. Power On Dremel LC40 Laser Cutter:
The machine must be powered on to
continue this procedure. Allow the
machine time to boot up the touch
screen operating system.
2. Gather Tools: A 2.5 mm hex wrench
(supplied) and thermal paper
(supplied) are required to perform the
mirror alignment procedure.
NOTE: DO NOT over-tighten or over-
loosen adjustment screws. Tightening or
loosening any of the three adjustment
screws on the mirrors or the red dot
diode will move the position in a
particular direction depending on the
positioning of the other screws. Some
experimenting is required to understand
the relationship of each screw and how
adjusting one affects the alignment
laser's red dot positioning.
When adjusting the screws, use the
absolute minimum turn of the hex wrench
to move the red dot or the mirror into
position. If one or two turns of the screw
from the just seated screw position does
not move the red dot into position, it is
recommended to release all three screws
back to the just seated position and start
over. Over tightening the screws can
damage the mirror holding plate. Check
for any loose screws at either the mirror
holders, the lens, or anywhere on the
Gantry to ensure efficiency during
alignment procedure.
