1St Mirror Alignment - Omtech PRO 2440 User Manual

6.4.2 1st Mirror Alignment

After ensuring the laser is well aligned between the laser tube and 1st mirror, check the alignment between the 1st
and 2nd mirrors.
1. Tap "manual" in the main menu.
2. Use the direction arrows on the control panel to send the 2nd mirror to the back of the bed along the Y axis.
3. Once set, place a piece of tape on the 2nd mirror's frame.
DO NOT place the tape directly onto the mirror. Turn on the machine and set the power level to 15% or
lower.
4. Tap to fire the laser. If the laser is not centered on the 2nd mirror, you will need to adjust the 1st mirror's set
screws accordingly.
a) To adjust the mirror, loosen the nut on the screw and then slightly turn the screw either clockwise or
counterclockwise. Each screw adjusts a different position or angle.
b) Keep track of which screw you are adjusting and the direction of adjustment. Do not turn the screw more
than ¼ turn at a time and, especially at first, test the position of the laser after each adjustment so that you
learn the effect of each change.
c) Test until the beam is well aligned and then retighten the nuts on the screws once all adjustments are
completed.
5. Use the direction arrows on the control panel to send the 2nd mirror to the front of the bed along the Y axis.
6. Once set, place another piece of tape on the 2nd mirror's
frame. DO NOT place the tape directly onto the mirror.
7. Tap to fire the laser and, if necessary, adjust the set screws on
the 1st mirror. Test again until the beam is well aligned and
retighten the nuts on the set screws.
