TESTS & ALIGNMENTS
3. Position the Laser Head: Move the
laser head into the upper left corner
(Location A) of the workspace, see
Figure 32.
4. Close the lid.
5. Using the LCD touch screen display,
test fire the laser (
by tapping Test Fire
on the Home screen) from the Test
Fire screen. The Fire button will
appear after all of the system checks
are passed. Press the button one time
and observe where the spot lands on
the thermal paper. If the spot does not
appear, repeat. If it still does not
appear, change position so it is
possible to look through the openings
in the tube guard and confirm that the
tube is actually firing.
6. Repeat Test Fire in other three
corners: Without removing the thermal
paper, repeat firing the laser once in
each of the other corners of the
machine (Lower Left B, Lower Right C,
Upper Right D). See figure 32.
a. Open the lid.
b. Position the laser.
c. Close the lid.
d. Repeat as in step 5. Observe which
mark is from which location.
7. Check Results: With the forth corner
test fire complete, open the lid and
observe the thermal tape. The four
burn marks should overlap each other
(see illustration). If they do not overlap
nearly perfectly, the mirrors will need
to be aligned.
8. If the dot is perfectly aligned a second
test is to place thermal paper under
the air nozzle on the honey comb at all
4 corners. Fire the laser using test fire
and verify that a smooth circle appears
on the paper. This ensures that the air
nozzle is not clipping the laser path. If
it is, fine-tune the nozzle by loosening
the set screw and adjusting.
9. If the mirror alignment test is not
successful then perform the Mirror
Alignment Procedure on page 65
10. If the mirror alignment test is
successful the laser cutter is ready
for use.

All 4 spots should be
within the diameter
shown in figure
above. Ideally
exactly on top of
each other.
3 spots together, 1
spot apart indicates
the gantry has one
corner physically
higher or lower than
the others.
