7. 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.
8. Reposition the Laser Head to “Close” Position: Now that we have a burn mark on our
thermal paper from a “far” ring of the laser, we want to re the laser from the closest position. Move
the laser head to the far left of the machine and test re again.
9. Re-Position X-Gantry back to “Far”: Jog or manually position the laser head to the far
right where you did the rst test re.
10. 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 #2 (not the red beam diode) to move the burn mark over the red beam.
11. Repeat Until Aligned: Check your results by repeating this process until the two burn marks
are both center and perfectly overlapping each other.
