Updated Oct 17,2025

Applicable scenarios

  • Due to deviation in the Z-axis verticality, some of the laser beam emits on the inside of the air nozzle, resulting in a double spot pattern on the material (double lines).

  • Other scenarios that the Z-axis verticality requires adjustment as determined by xTool technical team.

Important notes

  • After troubleshooting the issues according to the article Troubleshoot Double Lines on Engravings for xTool P3, adjust the Z-axis verticality as described in this article.
  • Use the included double-ended screwdriver to complete the operation.
  • If you are unsure whether to adjust the Z-axis verticality, please contact xTool after-sales service and provide a troubleshooting video along with the product serial number.
  • Do not loosen the camera module or distance measurement module on the Z-axis module, as this may cause camera or measurement errors.
