Maintenance

Mirror Alignment

The general procedure is to start from the mirror closest to the laser, use mirror adjustments to get the beam in a consistent position, then use bolts and translational adjustments to place the beam at the center of the mirror.

Mirror 3

1. Remove nozzle
2. First get consistent position by raising and lowering bed, and firing laser to find deviation.
3. Once consistent with changing Z position, move the beam position to the center of the tube.
4. Re-check concentricity by moving Z up and down.
