If the cor file is missing, please contact support@commarker.com with your machine model and SN code, or do a 9 Point Correction by:

1.Go to Laser Tools → Calibrate Galvo Lens → 9 Point Correction (Easy).

2. Based on the popped-out window, enter the working area of your lens, and the size of the box to output. Click Next to continue to the next step. 

3. Enter the settings based on your material and lens.

4. Put a paper on the engraving bed. 

Press up or down button to lift or lower the laser head until the 2 red light point overlap, which is the best focal point (the laser beam will be strongest). 

The measuring focal length of this machine can be found in the paper manual that came with the machine, the measuring distance is the length from the middle line of the Galvo to the surface of the engraving material. 

This parameter is measured manually, and each device has different focal lengths due to changes in laser sources and field lenses.

5. Click the Frame button and verify that the size of the frame is valid, or return to the previous step using the Go Back button if you need to adjust the size.

6. Click Start to mark the design. Once finished, do not move it. Click Next to continue to the next step. 

7. Select the LightBurn Dragon that matches the orientation of the output from your laser. Click Next to continue to the next step.

8.   Take out the paper, Use the ruler to measure and enter the horizontal distances between lines, as shown in the graphic. Click Next to continue.

Tips: Using a vernier caliper can make the measurement more accurate.

9.  Measure and enter the vertical distances between lines, as indicated in the graphic. Click Next to continue. 

10. The final page displays the resulting corrections that will be applied to each axis. Click Done to save the data.
