4-44 Setting Up and Using Laser Alignment Fixtures
The gridlines on the front panel should assist you in determining the
approximate movement(s) needed to rough the machines in. Gridline
spacing is 0.3 inches (7.5 mm). The following table shows recommended
moves based upon the gross movement of the laser beam on the sensor
head. Gross movements are discussed in vertical terms for simplicity.
Remember, you are seeing the extended centerline of both machines (see
figure below).
