Figure 7-8. Second axis positioning of optics
Place the optical square vertically on the machine near the reflector
(Figure 7-8).
Make sure that one of the optical square's slots points toward the laser
head and the other slot points up.
If your machine has T slots that run along the machine's travel path,
place the optical square so its side is parallel to one of the T slots.
To do this, place two base plates (p/n 10782A) against the edge of a slot
and butt the optical square's mount against the base plates. This ensures
that the optical square is parallel to the machine's travel path.
