8.3 Laser Path Alignment
A properly aligned laser beam is important for the overall efficiency of the machine and quality
of its work. This machine went through a complete beam alignment before shipping. When the
engraver first arrives and about once a week during normal operation, however, it is recommended
that users confirm that alignment is still at acceptable levels and that the mirrors and focus lens have
not shifted due to the movement of the machine.
•
Performing a beam alignment can expose the operator to small amounts of
radiation if performed carelessly.
•
Follow these procedures correctly and always take caution when performing
a beam alignment.
•
Perform a beam alignment at low power levels: 15% or less. Any higher
percentage will cause the laser to ignite the testing tape instead of marking it.
Be sure that you set the Max. Power (not Min.) to 15%
You will need to place a piece of tape at each stage of the laser path, marking it to confirm that that
stage remains correctly aligned. When it is not, you will use the laser tube’s brackets or the screws
on the back of the misaligned mirror to correct the problem. Once the provided tape runs out, we
recommend masking tape as it is easy to manage and use.
