If you notice that the pattern on the camera background doesn't align accurately with the actual engraving position, you can follow the steps below to calibrate the camera.
If the Distance Sensor has not been calibrated, we recommend calibrating it first. Following this sequence will provide the most stable and accurate results with LX2's functions:
Distance Sensor → Camera → Red Crosshair.
1. Prepare Materials
(1) Place the calibration material flat in the center of the Base Plate, ensuring it is securely fixed (e.g., using magnets) and lies perfectly flat.
- It is recommended to prioritize using the dedicated calibration material included with the device. If the included calibration material cannot be found, common materials such as A4 paper or kraft paper can be used as temporary substitutes.
- The selected material should ideally be larger than 210mm × 297mm but must not cover the black-and-white calibration dots around the edges of the Base Plate. The material thickness should be less than 0.5mm.
- It is recommended to use materials that produce clearly visible engraving results. Avoid highly reflective materials, as they make it difficult to see the engraving marks on the camera.
If you have installed the Riser Base, make sure to place the Base Plate on the LX2, not on the layers of the Riser Base.
2. Set the Focal Distance
Make sure the camera protective film has been removed before refreshing the background.
Method 1:
Step 1: Click the camera icon in the top right corner of the LDS software to refresh the background.
If the camera is unavailable, skip this step and proceed to Step 2.
Step 2: Click the "Auto Measure" button, position the cursor over the material, then click to start the automatic measurement process.
Method 2:
Step 1: Drag the Laser Module over the material.
Step 2: Click "Auto Measure", move the cursor to the red crosshair marker on the canvas, and left-click. The device will then begin the focal length detection process.
3. Open the "Camera Calibration" Function
(1) Click the gear button in the top right corner to open the Device Settings interface.
(2) Open the Device Calibration section, locate the "Camera Calibration" function, and click "Start" to begin the camera calibration process.
(3) Make sure the material used for calibration is in the center of the Base Plate and click Next.
4. Perform Camera Calibration
(1) Click "Rectangle Preview" on the right, and click "Preview" in the pop-up window. Make sure the processing area is within the material's range. If the rectangle preview exceeds the material's boundaries, click "Exit Preview", adjust the material position, and preview again.
(2) Click "Rectangle Processing" and press the device button to start processing. Wait for the machine to engrave the calibration pattern on the material and finish the calibration.
(3) Once the calibration is completed, click Apply. The calibration process is now complete.
5. Other Tips
(1) If you use other materials like paper and kraft paper to perform calibration, you can open the Recommended material list to check if there are corresponding engraving parameters. If none are available, you can manually adjust the engraving settings to achieve better engraving results.
(2) If the engraving area is positioned too close to the edge of the material, camera calibration may fail. Please use a material larger than 210 mm × 297 mm, and perform a "Rectangle Preview" before engraving to ensure that the pattern is centered on the material.
(3) The four black-and-white marker dots on the Base Plate are called calibration points. They are essential markers used to assist with camera calibration. If these marker dots are covered or damaged during normal engraving, it can cause the camera calibration to fail. You can replace them using the spare calibration dot stickers included in your toolkit before performing calibration.
After calibrating the Camera, we recommend calibrating the Red Crosshair next. Following this sequence will provide the most stable and accurate results with LX2's functions:
Distance Sensor → Camera → Red Crosshair.
