This guide applies to xTool P2.

About measurement accuracy: This is the discrepancy between the value obtained from the measure function and the real thickness or distance value.

If there is an error of more than 1mm when you use the quick measure function (long-range camera) around the center of the working area, you can troubleshoot first according to the following steps:

  1. Please make sure that the material and slats are even. If they are not, make adjustments and take new measurements.

  2. For measuring transparent or highly reflective material, place a piece of white paper on it before the measurement to prevent errors.

If the solution above does not solve the quick measurement error, please follow these steps to calibrate the quick measurement.


Calibrate the Quick Measurement

Things You Need:

  1. A Windows computer.
  2. The calibration tool for IR distance measurement. You can get the tool from customer support (


Note: If 3D printing equipment is available, download and print out the calibration tool model with light-colored filament. Put black tape on the same area of the calibration tool model as shown in the picture or blacken it with a black oil-based marker.

Calibration Steps:

1. Download the calibration software.
2. Put all the slats in position. Make sure they are seated properly, otherwise, the calibration may not be accurate.
3. Connect the machine to the computer with a USB cable.

4. Decompress the zip file and run the software. In the software screen, click on the 'Connect' and the 'Clear data' button.


5. Open the lid of the machine, click on the 'Red spot on' button in the software, and then put the calibration tool on the slats. Make sure the laser spot falls on the 3mm surface of the calibration tool.


6. Close the lid and click on the 'Capture' button for the 3.0 mm thickness text in the software.

7. After the capture, open the lid and change the position of the calibration tool so that the laser spot falls on the 6mm surface.



8. Close the lid and click on the 'Capture' button next to the 6.0 mm thickness text in the software.

9. The same goes for the 24mm surface. Finish the capture.

10. After all three thicknesses are captured, click on the 'Generate calibration file' button. You should see a graph and a pop-up window that says 'Generating the calibration file succeeded!' If it failed, please check if the slats are completely seated in position.

11. Open the lid and change the position of the calibration tool. Make sure the laser spot falls on the 3mm surface, and then close the lid. Click on the 'Distance measure verification (3mm)' button to get a readout of the thickness value.

12. If the value is under 0.5mm, click the 'Upload calibration file' to implement the calibration. If not, please repeat the above steps.
