Internal cycle process

1. The tool moves in Z direction until just before the software limit switches.
2. The tool is positioned simultaneously in X and Y directions above the laser focal point including the radius offset. (These values were defined in the file SysCalibConfigLaser.nc).
3. The device moves in Z direction across the focal point.
4. This is followed by 2 measurement to determine the tool length.
5. The device moves back in Z to the starting position.
