6. Allow time for any isopropanol to evaporate and then reassemble the
lens tube and place it back in the mirror housing, securing it with the
retaining screws
Laser Alignment
Tools Required:
• Phillips screwdriver
• Masking tape
• Mirror release tool
Time Needed: 30 minutes - 3 hours
●
Ensure cooling system is running before firing the laser
Overview
Working from the laser tube along the optical path to the lens and laser focus,
masking tape targets are placed over the various optical elements. The laser is
fired to mark the targets and adjustments are made based on the location of
the marks at various gantry positions.
When all the mirrors are adjusted correctly, the laser beam enters the top of
the lens tube parallel to the axis of the tube, and at it’s centre for all positions
of the head on both gantries. The lens position is then adjusted until the beam
is a tightly focused symmetrical dot at the focal point of the lens
The optical path is quite long, and high precision is required. When adjusting
the position of mirrors, the tube and the lens, make very small adjustments and
re-test the alignment.
Preparation
1. Access to the laser tube compartment at the rear of the machine is
required - move the machine if necessary (take care not to pull out the
cooling or air assist hoses)
2. Ensure the water cooling system is running
3. Make at least three masking tape targets, as explained below
