The optimal focus point is calculated in the JobControl Software. In the software you enter the material thickness and the lens used. Thanks to the bi-directional connection, the computer always knows exactly at what height the work table is positioned. Based on the information you entered in the software the table moves to the correct position with only one press of the button.
This focus mode is ideal for processing of materials of which the material thickness is known (eg. acrylics in 6mm).
