Recording the Quick
Start Program
Follow the instructions in this section to record the quick start program.
Clearance moves
CAUTION
Use clearance moves to avoid collisions between the probe
and the part.
Clearance moves are necessary to create CNC paths around the part and
other obstructions. For example, to safely move the probe from point A
to point C, insert a clearance move at point B.
If the clearance moves are omitted, the probe will move in a straight line
from point A to point C. The resulting collision could damage the probe.
