5.3.4 3rd Mirror Alignment
• Wear safety goggles during the entire aligning process.
• Avoid attaching the tape directly to the mirror.
• 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.
After ensuring the laser is well aligned between the 2nd mirror and the 3rd mirror, check the
alignment between the 3rd mirror and the workbed.
1. Unplug the air assist hose from the laser head.
2. Place a piece of masking tape across the bottom of the laser head and press it onto the nozzle
with some force. This will leave a ring mark that can help you check the accuracy.
3. Lay the tape right under the laser aperture and on top of the laserable scrap.
4. Press Pulse to manually fire the laser. You should be able to see a small mark on the tape. If it is
not noticeable, press Pulse again.
If the burnt hole is at the center of the masking tape, the 3rd mirror and the workbed are
aligned; if not, continue to step 4.
5. Adjust the 3rd mirror's setscrews accordingly as in
6. Repeat steps 2, 3, and 4 until the hole is at the center of the masking tape.
7. Retighten the nuts on the setscrews.
