Unlike the software overtravels, which define the perimeter of an area
from which the cutting tool may not exit, programmable zone 3 can define
either an area that the cutting tool may not exit or an area that the cutting
tool may not enter. This is determined by the current tool location when
programmable zone 3 is made active.
It defines an area that the cutting tool may not exit if the tool is currently
inside the zone when the zone is activated.
It defines an area that the cutting tool may not enter if the tool is
currently outside the zone when the zone is activated.
