Tool length: Q114

The current value for the tool length is assigned to Q114.
The Control remembers the current tool length even if
the power is interrupted.

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 preset 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.
