The “Autofocus” function does not work, what can I do?
Problems with Autofocus
With the Autofocus function, the processing table moves upwards automatically until the inserted material breaks through the light barriers. However, if the table moves downwards or not at all, you can proceed as follows:

The processing table moves downwards.
If the processing table moves up instead of down when activating the Autofocus, there are the following reasons and the corresponding troubleshooting:
- The Autofocus sensor is dirty. Clean the sensor according to the instructions!
- The sensor is faulty. In this case, contact Technical Support.

The processing table does not move.
If the processing table does not move when using the Autofocus function, then the light barrier is blocked. This can have the following causes:
- There is processing material in the light barriers. Check the location of the material and move the table downwards if necessary.
- The Air Assist nozzle of the laser head is in the light barrier. Check that you are using the correct Air Assist nozzle. Check the position of the side Air Assist (on the Speedy 100). If you are using the long Air Assist nozzle, you will need to adjust the focus manually using the focus tool.
