Warning! 

• 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.

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: Use the direction arrows on the control panel to send Mirror 2 to the back of the bed along the Y-axis.

Cooper screws: Mirror 2 Setscrew
Black frame: Mirror 2 Frame
Central mirror: Mirror 2

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 15% of the maximum power 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 Mirror 1's mounting bolts to slide it into a better position before fine-tuning the setscrews.

Silver bolts: Mounting Bolt
Cooper screws: Setscrew

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 you have finished adjusting the setscrews of Mirror 1, repeat steps 3–9 until the burnt hole falls perfectly at the center of the tape.

Step 10: When Mirror 1 is set, use the direction arrows on the control panel to send Mirror 2 to the front of the bed along the Y-axis.

Step 11: Attach another piece of tape to the frame of Mirror 2.

Step 12: Repeat steps 2–9 until the burnt hole on Mirror 2 is at the center of the tape.
