g. If the red dot does not match the
new SpotB2, tweak the red dot
(not M1) as in step 7.
h. Move the gantry to A, close the lid
and *Test Fire*. Observe the new
SpotA2. It should be only a little
closer to SpotB1.
i. Note: If at any time spots become
confusing, shift the paper or
remove it completely and start
with a clean piece. Spots will have
to be redone and *Test Fired* at
both A and B.
j. Continue this cycle of:
i. Fire Spot B,
ii. tweak the red dot,
iii. Fire Spot A,
iv. adjust M1 while the gantry is
at B
v. until the spots created are
perfectly on top of each other.
The spots on M2 may not be
perfectly centered, but should
certainly not extend off of the
edge of M2.
Step 5: Align Axis B-C (X-Axis)
using Alignment Laser's Red Dot.
Alignment of the B-C axis is often much
easier than the A-B axis due to proximity
of the gantry and experience learned on
the first axis. It cannot be stressed
enough that the A-B axis should be
aligned before attempting to align the B-
C. As with A-B and M1, once B-C is
aligned, do not continue to adjust M2.
Further adjustment of M2 will negate the
alignment of B-C.
1. Open the lid.
2. Place Thermal Paper as before on
Mirror 3.
3. Move the Gantry to Position C.
4. Note that it is possible that Mirror 2
can be adjusted far enough out of
range and potentially damage the
rubber of Mirror 3 when the laser is
fired. Look for the alignment Laser. It
should give an indication of where the
beam is pointing. Adjust Mirror 2 so
that the red dot is hitting the thermal
paper.
5. Close the lid and tap *Test Fire*.
Without removing the paper it may be
necessary to mark this spot. This is
SpotC1.
6. Adjust only the red dot beam to match
the SpotC1. As this is the furthest
distance it will take extremely small
movements of the screws to move the
red dot.
7. Move the head back to position B.
8. Close the lid and tap *Test Fire*
observing and marking the spots as
necessary. This is SpotB1.
9. As before if SpotC1 and SpotB1 are
not exactly on top of each other adjust
the red dot using Mirror2 this time to
adjust the location of the red dot half
way to SpotB1.
10. See steps above and repeat this cycle
of:
i. Fire Spot C,
ii. Tweak the red dot,
iii. Fire Spot B,
iv. adjust M2 while in position C.
v. until the spots created are
perfectly on top of each other. The
spots on M3 may not be perfectly
centered, but should certainly not
extend off of the edge of M3.
