The process is similar for triangular-shaped cantilevers, with the
exception that the laser will be obscured twice as it moves left to right
(over the two beams). The process is shown in
Figure 4-21 .
Figure 4-21 Steps to aligning the laser on triangular cantilevers
A potential error during the alignment process is to turn either of the
positioning controls too far in the wrong direction and to thereby lose
the laser spot altogether.
Figure 4-22 shows the positioning controls
when they are well out of alignment. The left-to-right knob will be
visibly tilted when the lateral alignment is far out, and the laser housing
will be moved to one side when the front-to-back alignment is out. The
easiest way to recover is to roughly center both controls again, moving
