Laser stops after a few seconds of burning

I have a ComGrow Z1, 10W.

Laser stops after a few seconds of burning.

I have tried files that I have burned before. Same result.

It’s able to frame just fine.

It seems like the laser just hangs… It doesn’t move after it stops. There is a yellow LED on the laser that is lit.

The green LED on the controller flashes slowly.

Any ideas?

Looks like it’s a USB cable issue.
