Three-Point Buck-In Procedure Using One Target
Figure 49 - Three-Point Buck-in Using One Target (Recommended Setup)
1. Position and secure the laser.
Position the laser as shown and turn the lever on the magnetic base to ON to lock it securely to the
metal surface.
2. Coarse level the laser.
Turn the selector switch on the laser to LASER & SCAN and turn the light switch for the bubble level
vials ON. Using the coarse micrometers and observing the position of the bubble levels, coarse level
the laser so that the laser plane is approximately parallel to the surface.
Note: At this point in the setup procedure, it is beneficial to perform the following coarse buck-in, particularly
if the levelness of the machine is in question.
a) With the laser in non-scanning mode, hold a tape ruler at the Near Position (see Figure 49). Point
the laser until it strikes the ruler and note the exact location where the laser beam hits.
b) Move the tape ruler to Far Position A (see Figure 49). Point the laser beam at the tape ruler and
adjust the center of the beam to hit the same location obtained in Step 2a.
c) Repeat this process until the laser hits the same location on the tape ruler in both the Near
Position and Far Position A.
d) Place the tape ruler at Far Position B (see Figure 49) and rotate the laser beam to hit the tape
ruler. Adjust the laser so that the center of the beam hits the same location recorded at the Near
Position.
e) The procedure is complete when the laser beam hits the same location on the tape ruler
for all
three of the target positions.
