TESTS & ALIGNMENTS
Mirror Alignment Overview
Observe all provided warnings and safety instructions when using
the Dremel LC40. Failure to do so may result in fire, equipment
damage, property damage or personal injury.
Fig. 31
Alignment of the mirrors is performed
before the Dremel LC40 is shipped.
However, before the laser cutter unit is
used for the first time and periodically
during its use, the mirror alignment
should be checked and adjusted if
necessary.
Misalignment most often occurs when:
• gantry is manually moved while the
motors are locked,
• air assist nozzle is displaced,
• main laser tube is replaced,
• mirrors / lens are replaced, or
• during shipping.
Alignment of the mirrors is necessary to
be certain that the path of the main laser
is perfectly parallel to both the Y and X
axis of the laser in all extreme corners of
the machine. Due to tolerance of the
mechanical assembly, every laser must be
aligned. The goal of alignment is is that
the laser beam should enter the lens as
perfectly centered and perpendicular to
the focus lens as possible. Improperly
aligned laser beam will result in the focus
point being out of line with the centerline
of the laser head (Fig . 31).
