Tool position

It is important that you observe the Start point X, Z tool position
before executing any of the turning cycles in expanded mode.
The rules apply for all cutting and infeed directions as well as for
roughing and finishing:
The starting point must not be located in the shaded area
The area to be machined starts at the Start point X, Z if the tool
is positioned before
only machine the contour area defined
If the Start point X, Z for internal machining is located above the
turning center, only the contour area defined will be machined
(A = Start point contour X1, Z1; E = End point contour X2, Z2)
