check the alignment. Briefly the logic is to have a perfectly straight beam path from Mirror 2 (Back top left) to mirror 3 (Left end of X axis). From mirror 3 to mirror 4 (the one in the lens carriage). Mirror 0 is for the red beam. Mirror 1 only controls where the beam hits the lens. If mirror 1 is adjusted incorrectly you may be hitting the air nozzle at the bottom of the lens assembly. If beam adjustment is necessary it may be easier to remove the lid for better access to the optics and to see what your doing. The first step is to check your machines alignment. We will check it in 4 places P1, P2, P3, and P4. (Diagram 1) Mirror 2 Mirror 3 P1 P2 P3 P4 Mirror 4 Back of Mercury To start place a piece of tan masking tape, transfer tape, or small white label to back of mirror 3’s housing. (Cover the hole the laser beam enters to get to mirror 3) Turn on the machine while holding down the Start and Pause key on the Control Panel. Remember to always wear safety glasses while doing any open beam tests.

Press the function Key and wait for the RAM test. It will take only a couple of seconds. Press the right arrow (2) until the display looks like this. Press the Down Arrow (3) until the display looks like the one below. Power should now read 5% 2 1 3 You are now ready to check your beam alignment. Position the X axis in PI (figure 1) The X axis should be pushed all the way back. Close the Lid . Pull the x axis arm toward you und look at the back. There should be a small brown/black burn mark. If there is not repeat blue above until you burn a small spot. If you burn a big spot you will need a new piece of tape and repeat again. Press the ENTER key fo about a second. A small amount of smoke should be seen Figure 2 shows a correct burn. Remember to always wear safety glasses while doing any open beam tests.

Small burn mark Figure 2 Position X axis to P2 (Bring it all the way forward) Put a small pen mark to the side of this dot so you will know which dot was fired first. Repeat steps in to create second dot. If the dots are on top of each other you are done with mirror 2. Please go to next page If not continue with this page. Blue If your dots look something like this you need to adjust mirror 2. Please note your Red Dot will NOT line up with your burn marks. Do not attempt to line Red Dot up it will NEVER be in the same spot as the C02 beam 1 2 Dot 1 is from P1 and 2 is P2 P1 dot will never move. We need to adjust the dot at P2 to hit the one from P1 Remember to always wear safety glasses while doing any open beam tests.

I bought mine at OSH Sears sells them as well as most hardware stores, Disconnect 3 wire clips 1 Black and Orange 2 Black and Red . (On older models the Black and Red wires will be in the back right) The B&R are the lids interlocks . The B&O is the Door Open LED. You will need to locate and press the release on these connectors and pull apart. The Grey Ribbon cable going to the control panel is snug. It pulls out by gripping the connector, or cable at the connector, and pulling down. (1) (2) (3) 1 2 3 Remember to always wear safety glasses while doing any open beam tests.

Tape the acrylic lid closed and remove entire lid. Lean the lid against the right side of the machine so that the Ribbon Cable can be plugged back in. It is keyed and can only be plugged in one way. Make sure the lid is propped so it will not slide . Place two of the lid screws as shown above in booth of the BLACK and wire connectors Black RED DO NOT insert screw into and connector.

1. First closest position to the mirror (P1 or P3) burn mark will not move. 2. We move P2 to line up on top of P1’s burn, and P4 to line up with P3. 3. The mirrors are aligned by adjusting 2 of the three screws on the prism mount. One screw moves the beam path up and down while the other is left and right. 5. You need alignment more accurate. as small of a burn mark as possible to make Place a piece of tape on the back of mirror 3’s sheet metal cover covering up the round hole. Do a test fire as described in . blue text on page 2 If your results are not similar to the above you will need to adjust mirror 2 so that only 1 burn mark and the red dot are visible on the test tape.. 4. The red beam will not line up with the burn marks. However, we adjust the screws and watch the results by following In other words if the P2 is .06” high and .03” left from P1’s burn, we will to move the red beam .06” down and .03” right. adjust the screws You may find it easier to put a pen mark as far from the red beam as P2 is from P1 Adjust the prism mount to move the red beam so that it is on the target spot you drew. the red beam’s motion.

(Looking from back of laser with lid off and cover removed) Screw 1 Up and Down Pivot Screw - do not adjust Screw 2 Left and Right Prism Mount Screw 1 Screw 2 Pivot Screw Mirror Once mirror 2 is adjusted we will now repeat all the steps to check and adjust P3 to P4. Do not forget to remove tape from back of mirror 3. Place your tape over the lens carriage opening. (The hole on left side of lens carriage.) As before P3 burn position will not move. Your goal is to get the dot from P4’s firing to line up on top of P3’s. The difference here is P4 is so far away the beam gets quite large. The burn mark will take longer to form and the dot is much larger. Burn in P4 1st to make visibility easier. Adjust the prism mount of mirror 3 using the offset screw driver. Follow the same process as used on mirror 2. Repeat until P3 falls on top of P4. You are almost done. Once you have adjusted the prism mount run the P2 burn again. If it lands on top of your original P1 burn your done. If not re-adjust to correct. You may wish to use a new piece of tape and run P1 and P2 again. Repeat as often as necessary until P2 line up directly on top of P1 Lock Screw Lock Screw Lock Screws must be tightened when adjustments completed. Adjustments should be made with lock screws snug, they may need to be loosened slightly if adjustment is made on screws 1 or 2 in a clockwise direction. (Please note tightening up Lock Screws may affect beam alignment adjust alignment as necessary) Remember to always wear safety glasses while doing any open beam tests.

Rub it to leave an impression of the opening. Make sure you remove the tape from the side of the carriage and fire for 1-2 seconds. Remove the tape from the bottom of the air nozzle. The burn mark should be near the center of the impression of the air nozzle opening. If it is close to the edge you may be hitting the air nozzle and not getting full power. You will need to adjust mirror 1 to move the beam away from the edge. Once completed re-check P1-P4 once more. Any adjustments at this point should be quite minor. To adjust mirror 1 you need to open up the back and left side to adjust Mirror 1, and Mirror 0. Mirror 0 is to position the red dot only. Mirror 1 only determines that the beam hits the center of the lens. Figure 5 Remove the 4 screws as shown below in figure 5 and open as in figure 6.

How to set Origin 1.Turn unit On while holding down two Red Control Panel Buttons. 2.The display will eventually say "Run Test Pattern" press the Right Arrow once. 3.The display will now say "Set Origin" press Enter 4. Press Auto Focus 5. Press the Arrow keys to position the Red Diode beam in the corner of the rulers as accurately as you can. Write down the X and Y values displayed on the control panel display on a piece of paper. 6. Press Enter 7. Turn Off Laser wait 10 seconds and turn it back on. 8. Set up a job with a small vector rectangle so that the top left corner is .5" from left, and .5" from top. Run the job. 9. Measure your results. The left and top edge of the rectangle should be .5" from the material edge. 10. If not repeat step 1-9. However this time rather the watching the Red Diode add or subtract your actual error in location from the X and, or Y values from Step 5. Press the Arrows to move it to display the corrected numeric X and Y location. 11. Repeat until you have the desired origin set. Keep the correct numbers written down below for future need. If Origin needs to be set again in the future you can use these numbers rather than using the Red Diode method as above. X Y . To align the Red Beam adjust the prism mount for mirror 0 so that the red dot hits the burn mark on the tape on the bottom of the air assist nozzle from your final test of mirror 1’s adjustment.
