This guide is tailored for xTool P2S machine.

Applicable scenario

While using the "Refresh background" feature, if you encounter a deviation over 1mm between the element on the software canvas and the actual processing result during the "Process on slats" mode, please follow the instructions below to troubleshoot before taking any further actions.

1. Check Material Flatness: Ensure the material is flat, without warping or deformation.
2. Check Slat Installation: Ensure the slats are properly installed and level.
3. Check Camera Module: Ensure the distance-view camera module is securely fastened; if loose, tighten the screws.

If the deviation persists after these inspections, it indicates the need for distance-view camera calibration. Please follow the calibration procedure below.

Calibration tools

• Windows/Mac computer
• Acrylic sheet (300*300*3mm) * 2
• A4 paper * 3
• Masking tape

Calibration procedure

Step 1: Access calibration mode

1. Click on the gear icon in the upper right corner to access "Device settings".
2. Based on your computer's operating system, press the corresponding keyboard shortcut to load the "Distance measurement" option:
3. • For Win: Ctrl+Shift+C
   • For macOS: Command+Shift+C
     
     
3. Locate the "Distant-view camera" and click on "Calibrate".

Step 2: Set up materials

1. Install all slats onto the laser device.
2. Place 2 acrylic sheets on the slats and attach 3 sheets of A4 paper on the acrylics.
3. Secure the paper with white tape and ensure the paper covers all the acrylic sheets as smoothly as possible (refer to the image below).
4. The higher flatness of the paper will result in greater calibration accuracy.
5. Click "Next" to proceed.

Step 3: Begin calibration

1. Hit the physical button on the laser device to initiate the calibration file processing.
   
   
    
2. Await the processing to complete.

Step 4: Verify calibration results

Once processing is complete, xTool Creative Space will automatically assess the calibration accuracy.

• If successful, a "Calibration done" message will appear.
• If calibration fails, repeat the steps above to recalibrate.

If None of the Above Works

If you have completed the above steps and still encounter any of the following issues:

1. After multiple attempts at software calibration, various errors persist, preventing calibration or resulting in calibration failure.

2. After multiple attempts at software calibration, the system indicates calibration success, but the actual images remain distorted or exhibit significant positioning errors.

Please follow the steps:

Step 1: Disable the Background brightness increase and adjust Fill light brightness to 50%.

Step 2: Go to Distant-view camera to calibrate the distant-view camera. Click Restore.

Step 3: Restart the device and computer.

(1) Restore factory settings, and restart the device and computer before proceeding with calibration.

(2) Prepare a piece of paper.

Before calibration, ensure the paper is flat. Secure the edges of the paper with white tape to keep the central area taut and prevent bulging, as shown below (Note: the paper must be blank and unprinted).

(3) Then proceed with camera calibration.

Step 4: Adjust the fill light brightness.

(1) If the calibration process still indicates calibration failure, adjust the brightness up or down based on the actual calibration conditions.

(2) Draw the curtains and turn off the ambient lights.

(3) Then recalibrate.

Step 5: Check the calibration result

(1) After calibration is complete, restart the device and computer.

(2) Test whether the camera has been successfully calibrated.

If you follow the above steps and find that calibration is effective, but issues persist, continue proceeding the four steps above. This will ensure successful calibration.

Step 6: Collect the information

If calibration still fails after attempting the above five steps, please collect the information according to the following steps, and then contact xTool customer service.

(1) Connect the device via a USB cable, copy the link according to your operating system, paste it in your browser, and press Enter.

• For Windows: 201.234.3.1:8329/snap?stream =0&mode=origin
• For macOS: 201.234.4.1:8329/snap ?stream=0&mode=origin

(2) The browser will automatically capture images using the distant-view camera. The resulting images will have a fisheye shape (as shown below), which is normal. Observe whether the edges of the image are distorted or warped.

• If the image is distorted or warped, contact xTool after-sales service (support@xtool.com) for a new camera to replace.
• If the image is not distorted or warped, it indicates that the camera is functioning properly. Proceed to the next step.

(3) Follow the steps below to obtain the tool file. After compressing the tool file, please send it to xTool after-sales service (support@xtool.com) by email.
