Ortur Laser Master 3 - Alarm Beeping

Hello everyone! I’m having an issue with my machine Ortur Laser Master 3 and can’t find a solution.

​I am using Windows 11 and LightBurn, the latest version updated. Yesterday, the machine suddenly stopped and started beeping. I restarted it but the sound persists during the engraving work.

​Additionally, the laser lights flash between yellow and white the whole time, although it’s still functioning.

​What could be causing this?

Thanks!

Nope… I am wrong..
