¶ 1.Reconfigure the camera wiring
¶ 1.preparatory work
Prepare a data cable that can convert the Type-C male connector to a USB-A male connector.
Prepare a data cable that can convert the USB-A male connector to another USB-A male connector.
Prepare a data cable that can convert the USB-A female connector to a USB-A male connector.
Prepare a USB Hub.
¶ 2.Remove the side cover
1.First, unscrew the two screws on the left door and remove the left side of the machine's door.
2.As shown in the figure, connect 3 data cables to the USB hub.
¶ 3.Modify the wiring of the camera
1.Remove the USB extension cable of the machine from the motherboard and connect the A data cable.
2. Connect the B data cable and the C data cable to the positions shown in the following diagram.
3.Remove the adhesive tape from the USB Hub and stick it onto the side cover as shown in the picture.
4.After the machine has completed its startup, connect the device to the computer using a USB data cable, and then open LightBurn.
Note:
After the renovation is completed, you need to turn on the device and wait for it to automatically complete the connection process. Then, connect the device using your USB data cable.
It is not supported to repeatedly plug and unplug the device for reconnection after a successful connection. It is not supported to insert the USB data connection device into the machine first and then turn on the device.
¶ 2.Import Preferences
1.Download the calibration configuration file from the link.
————————Camera calibration profile.lbprefs————————
2.In the menu bar: File -> Preferences -> Import Preferences. Then import the Camera calibration.lbprefs file that you just downloaded.
¶ 3.Calibrate the alignment of the camera
¶ 1.Place the carving materials
Prepare four wooden boards or four sheets of kraft paper and place them on the honeycomb board.
¶ 2. Adjust the height of the Z-axis to achieve focusing.
During the process of marking points, in order to achieve better clarity and accuracy, it is necessary to lower the Z-axis height by 5mm to ensure that the distance between the marking material and the laser head's light emission position is 5mm.
¶ 3.Select the cameras that need to be calibrated and aligned.
Click on the "Laser Tool" in the menu bar -- then click on "Calibrate Camera Alignment" -- select the "Fixed Camera" option on the left, and choose your camera.

¶ 4.Carving marking points
Step 1
Place the material at the center of the laser working area -> Set the proportion scaling, and it can also automatically adapt to the working space -> You can click on the border of the third step to preview the range. To achieve the best effect, please increase the Scale (scaling) value to the maximum amount that you can adjust.
Step 2
Enter the appropriate Speed and Power settings. These settings may vary depending on the materials used. The power can be adjusted from low to high to achieve the best carving without burning through. Therefore, we are unable to provide these for you.
Step 3
Preview the border for the pattern layout to ensure it is placed on the material you are using.
Step 4
Start the carving process. If it is not dark enough, you can adjust the settings and run it again. When the pattern is clearly visible and easy to view, click "Next".
¶ 5.Mark the center of the target
Make sure that the captured image is clean and without distortion.
In this step, each target needs to be marked by double-clicking its center in sequence. You can also use zooming in and out to help you mark more accurately.
When double-clicked, a red "+" mark will appear. Place the labels in numerical order (1, 2, 3, 4) at the center of the four targets. If an error is made, you can double-click near it to move it, or click "Undo Last" to delete it and try again.
After completion, click "Next" and then click "Finish" to store your calibration results.
¶ 6.Add the camera image to the canvas
Click on the menu bar and select "Window" to check the "Camera Control" option.
Select the camera and click "Update Overwrite" to update the camera image onto the canvas.
Congratulations! You have completed all the settings for camera calibration.
¶ 4.When there is an error in aligning the camera with the canvas, the solution is...
1.When you encounter the following errors, you can solve them by calibrating the camera alignment and modifying the positions of the marking points.
2.Re-calibrate the camera alignment process, secure the carving material firmly to prevent any movement.
3.When you encounter a deviation similar to that shown in Figure 1, the actual engraving position is slightly to the lower left. The corresponding position where the marking points need to be modified should also be shifted in the same direction for marking.
Conversely, if the actual carving position is towards the upper right corner, the corresponding marked position also needs to be marked in the same direction towards the upper right corner.
If you still have any questions, you can refer to the calibration tutorial of "LightBurn" or contact the LightBurn customer service.
