##To adjust beam alignment, adjust the mirror orientation by turning the thumbscrews on the mounting plate. Turn only a small amount and re-fire the laser to get a sense of how sensitive the mirror adjustments are. | ##Placing tape or targets on each mirror, moving the mirror to nearest position of the previous mirror. | ||
###[[File:Laser-mirror-alignment.webm|none|thumb]]The thumbscrews on the rabbit mirrors are in a different location than this video but the principles of alignment still apply. The thumbscrews change the yaw, pitch or roll of the mirror plate. | ##Fire the laser at the nearest position. Move the mirror the farthest position and fire again. Compare where the burn marks are - if they are at the same spot, the mirror is aligned along the gantry. If there are two burn spots, the mirror must be aligned. | ||
##Check the beam alignment of each mirror at the nearest and farthest extent that the gantry will allow. This will ensure the beam is aligned along the entire travel pathway of the mirror. | ##Adjust the mirror alignment | ||
##To reset Z height on laser head - Move Z axis bed to top. Put down piece of paper.
