xTool P2S on Mac - Communication with controller failed

Hi everyone,

I’m hoping someone can help. I’m using:

  • xTool P2S
  • MacBook Air M1
  • LightBurn 2.1.03
  • USB connection

My problem is:

  • xTool Studio connects to my P2S and shows Ready.
  • My Mac detects the P2S.
  • I imported the official xTool P2/P2S .lbdev device profile.
  • The device is configured for Serial/USB.
  • When I open Machine Settings in LightBurn, I get “Communication with controller failed.”

I have already:

  • Restarted my Mac.
  • Restarted the laser.
  • Re-imported the official xTool device profile.
  • Verified the machine works in xTool Studio.

Is this a known issue with the current P2S firmware, or is there another fix?

Also, my LightBurn trial expires today. If this is a compatibility issue, would it be possible to extend my trial while I work through it?

Thank you very much for any help.

If you go to Help Menu > License Management, there should be a button to extend trial. They will allow you to extend a couple times.

Make sure that the xTool software is disconnected before attempting to connect to Lightburn.

This video “might” help find your connection.

I’d really appreciate it if you could tell me the result.
