5 Maintenance
Place a piece of tape at each stage of the laser path. DO NOT place the tape directly onto the mirror.
1.
2. Turn on the machine.
3. Set the Max. Power (not Min.) parameter to 15% or lower. Any higher percentage will cause the
laser to ignite the testing tape instead of marking it.
4. Press Pulse to manually fire the laser and confirm that the stages remain correctly aligned.
When it is not, use the laser tube's brackets or the setscrews 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.
5.3.1 Laser Tube Alignment
The laser tube is where the laser beam is generated. Once emitted from the tube, the laser hits the
1st mirror first. Follow the steps below to check the laser hits the 1st mirror right in the center.
• Wear safety goggles during the entire aligning process.
• Avoid attaching the tape directly to any of the mirrors.
• Less than 15% of the maximum power (not Min.) should be sufficient to leave a
clear mark without setting the testing tape on fire.
• Always make sure the path is clear between the laser and its target. Never
allow foreign objects between the laser and its target. Always close the cover
before firing the laser. Do not look directly at the active laser through the
cover during this procedure.
To test the alignment of the laser tube with the 1st Mirror:
1. Cut out a piece of masking tape and place it on the mirror's
frame. DO NOT place the tape directly onto the mirror.
2. Turn on the machine.
3. Set the Max. Power (not Min.) parameter to 15% or lower.
