This article only applies to xTool P2 using the distance sensor shown in Pic 1.

• You can confirm which distance sensor your xTool P2 is using by removing the upper cover of the laser module.
• If you find that P2 uses a different sensor like in Pic 2, you need to refer to another guide to perform an accuracy calibration for aimed-measure.

Issue description

In slats flat mode, when using the aimed-measurement function in the center of the processing area, you might encounter a thickness/distance error exceeding 0.5 mm. You can follow the steps below for troubleshooting.

1. Check the flatness of both the material and the surface flats. Ensure they are flattened, then attempt the measurement again.
2. For transparent or highly reflective materials, the measurement may result in errors. Place a sheet of white paper on the material before measuring and try again.

If the above doesn't resolve the issue, please follow the next steps to calibrate the aimed measure.

Material used

• An acrylic sheet with a thickness of 3mm.
• A two-in-one screwdriver (comes with the machine);
• An L-shaped hex key, 1.5mm (comes with the machine);

Calibration steps

1. Put the slats in position.

• Ensure proper and complete seating of the slats into the slots; otherwise, the calibration may be inaccurate.
• Verify sufficient slats to support the material.

2. Remove the upper cover of the laser module.
3. Place the acrylic sheet at the center of the processing area.
4. Connect P2 to XCS using the USB cable.

5. Put the machine lid down.
6. Click the icon on the top right corner and go to "Setting".
7. Press the appropriate key combinations based on your operating system.

• For Windows: Ctrl+Shift+C;
• For Mac: Command+Ctrl+C;

8. Then you will see the "Distance measurement" in Setting;

9. Click on "Calibrate" to access the configuration interface displayed below.

10. Enter the provided IP address into the input field and then click on 'Connect'."

• For Windows: 201.234.3.1
• For Mac: 201.234.4.1

11. If the connection fails, open your browser, input the following link into the address bar and press enter:

• Enter the IP address into the input field.
  • For Windows: 201.234.3.1
  • For Mac: 201.234.4.1

12. After connection, click "Calibrate aimed-measure" as shown below.

13. Use the interface's arrow keys to move the laser module to the center position above the surface of the acrylic sheet.
14. Click "Process a point".

15. Afterward, the laser will mark a point on the sheet.

Note: If no mark is visible, position a white paper sheet on acrylic for better visibility.

16. Inspect both the red spot from the distance sensor and the laser mark left on the sheet.

17. Move the laser module to allow the red laser spot to fall perfectly at the point processed in the previous step and click "Done, next".

18. Remove the slats, and position the acrylic sheet directly onto the base plate as illustrated below.

19. Repeat the preceding steps from 14 to 17 to laser a point and then fall the red spot on it.
20. After clicking 'Done, next', the software will begin generating the calibration data.

• During this process:
  • If the two points completely overlap, click "Done, next" to proceed directly to step 23;
  • If the laser module shifts, the red laser spot does not fall fully on the burn mark, follow the steps below to adjust the distance sensor.

21. Using Pic 3 as an example:

• In Pic 3, the red laser spot is shifted downwards and to the left.
• To rectify this, follow these steps to adjust the screws on the laser module based on Pic 4:

• Horizontal Adjustment:
  • Loosen screws 1 and 2 using the screwdriver, as shown in the picture.
  • Turn screw 3 clockwise or screw 4 counter-clockwise to shift the red spot towards the right.
  • Once the red spot aligns horizontally with the burn mark, securely tighten screws 1 and 2.
• Vertical Adjustment:
  • Loosen screws 5 and 6 with the screwdriver.
  • Turn screw 7 clockwise or screw 8 counter-clockwise to move the red spot upwards.
  • After adjusting the red spot to the desired vertical position, securely tighten screws 5 and 6.

Caution: Avoid using the screwdriver in contact with the circuit board during the process to prevent a potential short circuit.

22. Adjust the screws by the above method, and after making the red spot overlap with the burn mark as closely as possible, click "Done, next".

23. Take out the acrylic sheet and install one slat into the slots with the thicker side facing upward.
24. Control the laser module to move and make sure that the red spot falls on the slat surface.

25. Put all the slats in position. To test the calibration result for the aimed measure, use XCS to measure the distance or thickness of the material.

• To ensure the accuracy of the test, use the acrylic sheet for testing purposes.

25. If the measurement error exceeds 0.5 mm, please repeat all the steps for recalibration.
