Coordinates after probing during program run

The parameters Q115 to Q119 contain the coordinates of the
spindle position at the moment of contact during programmed
measurement with the 3-D touch probe. The coordinates refer to
the datum point that is active in the Manual Operation mode.

The length of the stylus and the radius of the ball tip are not
compensated in these coordinates.
