Starting point of contour in XY plane
Enter the coordinates for the starting point and target point in the first
contour element of the contour. Entering the starting point is only
possible in the first contour element. In subsequent contour elements,
the starting point results from the previous contour element in each
case.
Press the Contour menu key.
Press the Insert element soft key.
Specify the starting point.
In smart.Turn, ICP generates a G170.
