Tools You May Need:

Flat Head screwdriver

Allen Wrenches - 2.5mm and 3mm

1 Roll of Masking Tape

1 Safety Goggles/Glasses SAFETY INFO: C02 Laser Radiation, PPE, & Fire Suppression

3mm Allen bit and extensions for Tube mount backside bolts

Hardware Functions at the Tube Mount Brackets:

Left and Right Movement- Lateral	Up and Down Movement - Vertical
There are 4 total silver screws (2 for the front and 2 for the rear bracket) that use 3mm Allen Wrenches. Loosen (do not remove) all 4 and adjust the tube evenly in a lateral direction to move the pulse spot of the laser beam on the Mirror #1 tape. Once the spot is centered on the lateral plane, tighten the 4 silver screws.	To raise or lower the tube, loosen the grub screws (circled) with a 2.5mm Allen wrench and then use the thumb wheel to raise and lower the tube. Then once done, tighten the grub screws. Try to raise and lower the front and rear of the tube together. Each bracket will have its own thumbwheel and grub screws.

Hardware functions at the mirrors:

	Gold Knobs are the adjustment knobs, the silver bolts are for holding the mirror in position.

 

Get familiar with Control Screen:

      On LCD panel, set the output power to the recommend power from the table in the above section. You will need to set the min and max power. You will use the Pulse button to fire the laser, the longer you hold or the more times you press the button the more laser power will be used. Too much laser power will catch the tape on fire or blow right through the tape.

 Laser Beam Alignment Procedure  Basic Overview:

Before you start adjusting the mirrors, please loosen the stop rings on the three gold knobs and then loosen the silver bolts.  After you are done adjusting the mirror, tighten the gold stop rings and then silver securing bolts and check the beam path again by pulsing the laser into tape. If needed, please repeat the Laser Beam Path adjustment steps. Note that when you are tightening the silver bolts, the mirror alignment may be affected so you have to counteract that prior to tightening the bolts.

1. Check the Tube to tape on Mirror #1 standoff pulse spot as an initial health check of the tube position. Adjust as needed to center the Laser Pulse.
   
2. Then Check Mirror #2 to Tape on Mirror #2 - Adjust and Verify that Laser Pulse spot is in the center at both the near and far locations
   
3. Then Check Mirror #3 to tape on Mirror #3 - Adjust and Verify that Laser Pulse spot is in the center at both the near and far locations

You will need to place tape on the Mirror #1 standoff and pulse it to check that the pulse is centered. If the pulse is not centered, use the adjustments on the Tube Brackets to center the pulse up.  For this part of the alignment, the Red Dot was blocked by sticking tape over it. The dust cover was also removed for more clearance (130w and 100W tubes only)

Place Tape On Mirror #1	Laser Pulse Centered on Mirror #1

Stick a small piece of mask tape on the mirror #2 and then use the button on the Alignment screen to move mirror #2 to the Upper Left position of the bed.

      Pulse the tape on mirror #2. If the pulse is off-center, loosen the two silver bolts on mirror #1 and adjust mirror #1 and pulse again until the burn spot is in the middle of the tape. Depending on where the pulse is at the start of this procedure, it may not require any adjustment. You may need to replace the tape a few times as you dial in the pulse position. Once you have the pulse centered with mirror #2 in the Upper Left position go to the next step.

      Once you have the pulse spot centered in the Upper Left position on the Mirror #2 standoff, its time to move mirror #2 to the Bottom Left Position using the Alignment Screen and adjust mirror #1 again. Since Mirror #2 is further away from mirror #1 now, the error in alignment will be more pronounced and the adjustments done on the mirror adjustment screws will move the pulse spot even more. The goal is to center the pulse spot on the mirror #2 standoff in the Bottom Left position and then check again at the Top Left. Once the pulse spots are centered at both positions, tighten the silver bolts to secure the mirror. Then recheck one more time prior to moving onto the next step of adjusting mirror #2 to the tape on mirror #3 since tightening the silver bolts can shift the alignment some.

      Similar to what was done in step 2, we now need to get the pulse spot centered on the laser head Mirror #3 Entry hole position. This time we will adjust Mirror #2.

Mirror #3 In Bottom Left position	Tape on the Mirror #3 Laser Head Entry Hole

      Pulse the tape on mirror #3. If the pulse is off-center, loosen the two silver bolts on mirror #2 and adjust mirror #2 and pulse again until the burn spot is in the middle of the tape. Depending on where the pulse is at the start, it may not require any adjustment. You may need to replace the tape a few times as you dial in the pulse position. Once you have the pulse centered with mirror #3 in the bottom Left position go to the next step.

      Once you have the pulse spot centered in the Bottom Left position on the Mirror #3 Laser Head Entry Hole, its time to move mirror #3 to the Bottom Right Position using the Alignment Screen and adjust mirror #2 again. Since Mirror #3 is further away from mirror #2 now, the error in alignment will be more pronounced and the adjustments done on the mirror adjustment screws will move the pulse spot even more. The goal is to center the pulse spot on the mirror #3 Laser Head Entry Hole in the Bottom Right position and then check again at the Bottom Left. Once the pulse spots are centered at both positions, tighten the silver bolts to secure the mirror. Then recheck one more time prior to moving onto the next step of adjusting the red dot since tightening the silver bolts can shift the alignment some.

Adjustment Notes

Reference Image

Adjust screw A: Loosen the nut and rotate clockwise, then the laser beam will moves left; if you rotate counter-clockwise, the laser beam will moves right. Adjust Screw B: Loosen the nut firstly. If rotate clockwise, the laser beam will moves upward; if rotate counter-clockwise, the laser beam moves backward. Adjust screw C: Loosen the nut. If rotate clockwise, the laser beam will moves forward and right; if rotate counter-clockwise, the laser beam moves backward and left. Silver bolts D: Please loosen these three white screws before adjusting Screw A/B/C. After finish, tighten these three white screws (and lock all nuts of screws)

Why Adjustment is needed	Targ Result
	Adjust Screw A/B/C so as to change the angle of the third reflective mirror. If the laser beam comes out from the bottom center of the laser head, it proves that third mirror is in right 45°.

Place a piece of 10mm acrylic under the laser beam. Pulse a laser beam into the acrylic, check if the line is vertical or not. See the table below for expected results

Compare results	How to Adjust Until Correct

Once correct, tighten all the adjusting screws and white screws and move the laser head to four corners to test the laser beam verticality. If the problem still exists, please contact with our tech team in time by email:  support@thunderlaserusa.com .

1.Use the buttons on the laser machine screen to move the laser head on the approximate middle of the honeycomb table.

2.Place a piece masking tape over the left side of the third mirror laser head, and pulse a dot on the center, like below.

3. Use the three adjustment screws on the Red Dot Pointer Mount to move red dot to the mark dot on the tape, like below.
