8. Re-Position Focus Head back to “Far
”
:
Use the thumb screw to loosen and position the
focus lens as far down as it will go.
9. Check Results:
There should be two observable burn marks on the thermal paper. If they
overlap perfectly you can move on to the next mirror. If they are apart, adjust the three 2.5mm hex
screws on Mirror #3 (not the red beam diode) to move the burn mark over the red beam.
10. Repeat Alignment Test:
To ensure your laser is aligned, repeat the alignment test by test
firing the laser in all four corners and checking that all the burn marks perfectly overlap each other.
4. Close Safety Lid:
Safety measures should make it impossible to fire the laser with the safety
lid open. Regardless, never intentionally fire the laser with safety lid open.
5. Test Fire the Laser:
Press the Fire Laser Icon button on the touch panel. You will see a burn
mark on the thermal paper.
6. Adjust Red Beam:
Using your 2.5m hex wrench, make micro adjustments to the three
adjustment screws of the red beam diode, and position the red dot exactly over the burn mark.
7. Reposition the Focus Lens to “Close” Position:
Now that we have a burn mark on our
thermal paper from a “far” firing of the laser, we want to fire the laser from the closest position. Move
the focus lens as far up as it will go. Test fire the laser again, leaving a second burn mark.
