Exiting the contour programming
 Press the END key: smarT.NC exits the contour
programming and returns to the state from which you
started contour programming: Either to the last active .HU
program, if you started from the smarT.NC main row, or to
the entry form of the machining step, if you started from the
form.
If you started contour programming from a form, then you
automatically return to that form after exiting the generator.
If you started contour programming from the main menu,
then you automatically return to the last selected .HU
program after exiting the programming.
