17.10 Presetting with a 3-D touch probe
Overview
Refer to your machine manual.
The machine tool builder can disable presetting in
individual axes.
If you try to set a preset in a locked axis, the control will
issue either a warning or an error message, depending
on what the machine tool builder has defined.
The following soft-key functions are available for setting a preset on
an aligned workpiece:

respect to the current preset (possibly a manual preset
from the Manual operation mode). The datum shift is
included in the position display.
