In order to achieve perfect results on the material, the laser beam must be perfectly collimated (focused) for the laser process. The autofocus with sensors includes light barriers, which are installed laterally in the enclosure. If the autofocus is enabled on the keyboard of the laser system, the processing table will move up. As soon as the material that you inserted beforehand has passed the light barriers, the upward movement of the table will stop. Focusing is then complete and you can start the laser process.
