This option enables the Z data channel of the card.
It is required to control 3-axis scan heads.

If an 3-axis scan head is used for marking on flat parts, the third scanner axis is used instead of a F-Theta objective to keep the laser focus constant on a plane surface, the option FlatLense is required and a 3D correction file has to be used which also contains Z bit values for every correction point.

If the 3-axis scan head is used for marking on curved parts (real 3D vectors), both options FlatLense and Optic3D are required.
