Gweike Cloud Pro II (50W CO₂) Laser Cutter randomly pauses during jobs

Hi everyone,

I’m having a recurring problem with my Gweike Cloud Laser Cutter & Engraver with Rotary CO₂ (50W) Pro II — during engraving or cutting jobs, it keeps pausing by itself, as if someone were pressing the Start/Pause button. I have to press the button repeatedly throughout the job to get it to continue.

I’ll attach a video showing exactly what happens.

I’ve tried:

  • Running jobs via USB with LightBurn,
  • Running offline via USB with the Gweike Cloud software,
  • And running online via Wi-Fi through the Gweike Cloud web app —
    but the issue is the same every time.

Has anyone experienced this before or knows what could cause it?
Could it be a firmware, hardware, or connection problem (e.g. grounding, static, or USB interference)?

Any help or suggestions would be greatly appreciated!

Thanks in advance,
Lukáš
