Point strategy

With point strategy, a point must be defined with a Z coordinate that is less than or equal to the down_Start (escape point) height and with a radial coordinate that is greater than or equal to 0. There are three possible paths depending on the current position in the down channel:

1. Z_point ≤ Z_start                                                         Flat_escape
2. Z_point > Z_start, radius_point ≤ abs(radius_start)          linear motion up to the point followed by flat_escape
3. Z_point > Z_start, radius_point > abs(radius_start)          perpendicular motion up to the horizontal of the point followed by flat_escape.

These three variants are shown in the figure below:
