Warning! 

• Wear safety goggles during the entire aligning process.
• Avoid attaching the tape directly to the mirror.
• 8 mA or 11% 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.

The laser emitted from the laser tube bounces off Mirror 1 and reflects off Mirror 2. This means that when the laser tube is properly aligned with Mirror 1, lining up Mirror 1 will align it with Mirror 2. 

Tools Needed: Masking Tape

Step 1: Open the cover and gently move the X-axis rail along the Y-axis to send the 2nd mirror to the back of the bed as shown.

Step 2: Attach a piece of masking tape to the mirror’s frame.

Step 3: Put on safety goggles, turn on the machine, and set the power level to 11% or lower.

Step 4: Close the cover.

Step 5: Fire the laser.

Step 6: Check that the burnt hole on the tape is at its center.

If not,

Step 7: Cut the power to your laser and open the rear access door to expose Mirror 1 as shown.

Note: If the last burnt hole is way off-mark, you may need to loosen the mounting bolts of Mirror 1 to slide it into a better position before fine-tuning the setscrews.

Step 8: Carefully turn the setscrews on Mirror 1 to adjust the angle and position of Mirror 1.

Note:

• Each screw adjusts to a different position or angle.
• 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. Test the position of the laser after each adjustment to learn the effect of each change.

Step 9: When finished adjusting the setscrews of Mirror 1, repeat steps 3–8 until the burnt hole falls perfectly at the center of the tape.

Step 10: When Mirror 1 is well aligned, tighten the setscrews on Mirror 1.

Step 11: Gently move the X-axis rail along the Y-axis to bring Mirror 2 to the front of the bed.

Step 12: Attach another piece of tape to the frame of Mirror 2.

Step 13: Repeat steps 2–8 until the burnt hole on Mirror 2 is at the center of the tape.
