Test the Focal Length

1.Start the device and connect it to the computer using a PC cable.

2.Launch RDWorksV8 software and connect to the device.

3.Click sequentially:config >> System Settings >>Set Map for pen axes to”Z”

4.Open the focal length test file and click “Download” to transfer the file to the device.
5.Place the wood board on the processing platform and press the material flat.

6.Move the laser head to a suitable processing position, then click sequentially: Positioning >> Start >> Process the drawing. 



7.After processing is complete, observe the wood board and find the smallest spot. This is the optimal focal point, and the number to the right of the spot is the focal length.

Note: The focal length of each device is different, please refer to the actual test results for accuracy
