Issue description

If you encounter a pop-up error message in xTool software when calibrating the capacitive sensor, please follow this troubleshooting guide to resolve this issue.

Possible causes

• The image captured by the camera is abnormal.
• Slag is built up on the nozzle.
• The material to be processed is not metal.
• Cutting tip related
• • The cutting tip is not well installed.
  • The carriage is contaminated.
  • The cutting tip cable is damaged.

Detailed procedure

Step 1: Check if there is an error message

Check if there is an error message entitled "Capacitance value abnormal" when calibration fails in xTool software.

• If the error message still exists, follow this guide to resolve the issue.
• If not, proceed to the next step.

Step 2: Check the nozzle and the camera

1. Power off the machine.

2. Remove the nozzle from the cutting tip.

3. Check for obvious metal debris on the nozzle. If there is any, use a lint-free cloth dipped with alcohol or an angle-grinder to clean the nozzle.

4. Ensure that the calibration is performed on a solid section of a metal material (with no cutouts), and that a proper image can be captured by the distant-view camera.

5. Calibrate again on the other position of the canvas.
6. If the issue persists, please prepare a video recording your troubleshooting process and results and contact xTool Customer Service for further assistance.
