5.4.3 2nd Mirror Alignment

After ensuring the laser is well aligned between the 1st mirror and the 2nd mirror, check the
alignment between the 2nd mirror and the 3rd mirror.
1. Use the direction arrows on the control panel to send the 3rd mirror to the left of the bed along
the X axis.
2. Place a piece of tape on the 3rd mirror's frame.
DO NOT place the tape directly onto the mirror.
3. Press Pulse to manually fire the laser and observe if the laser is at the center of the masking
tape on the 3rd mirror. If so, the 2nd mirror and the 3rd mirror are aligned; if not, continue to
step 4.
4. Adjust the 2nd mirror's set setscrews accordingly as in
Page 81.
5. Use the direction arrows on the control panel to send the 3rd mirror to the right of the bed
along the X axis.
6. Repeat steps 2, 3 and 4 until the beam is well aligned.
7. Retighten the nuts on the setscrews.
