When the Autofocus function is in effect, the laser machine table automatically moves upwards until the material crosses the light barries, which determines the focus point. Although, there are times where the Autofocus may not work or will move downwards, in this case, you can do as follows:
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.
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.
If the table still does not move, adjust the focus manually using the focus tool. Contact Technical Support to solve the problem.
