Laser head stops after approx. 1 - 1 hour 10 minutes

I have a Neje Master 2S max running GRBL. After running shortly the laser head stops moving. I’ve shut off all the sleep timers on the computer that I can think of(USB, sleep…). I has ran 6 hour burns in the past without issues. What’s something that i’m missing?

Any alarms or errors presented in the console window when this happens?

We have seen stops triggered by 'error:9 - G-code locked out during alarm or jog state. Some motion control boards have ‘shock detection’ that shuts the laser off in case the machine is bumped or moves beyond some setting as a safety mechanism.

Without more information, hard to diagnose the issue.
