Calibrating Focus Length for the Aurora Series

Calibrating Focus Length for the Aurora Series

1. Set the Marking Object and Marking Parameters

Draw a 10 x 10 mm square and set the parameters for the brightest beam during engraving.

We use the laser software EzCad2 for the demo.

Below are the recommended parameters for the Q-switch 50W laser as a reference.



2. Continuous Marking on the Material

Stainless steel is recommended because the bright light produced by the beam is easier to observe during engraving.

Aurora 8 and 8 pro

a. Before the start, connect the TLTool and the Data settings are as follows.

b. Continuous marking.


Once calibration is complete, ensure continuous marking is disabled.

3. Move Galvo to Find the Brightest Location

Press the Up and Down button to move the Galvo.




Observe the location where the beam is brightest.


After observing the brightest location, stop marking and keep the Galvo stationary.


4. Set the Focal Length

Aurora 8 and 8 PRO
