20w ortur laser stopped burning with 15 minutes of initial use

Hello,

Any help is appreciated. I set up my ortur 20w LM 2 today. Installed the grounding kit before even firing it up. Installed lightburn, installed my laser. Did a test burn for power and speed and about 10 minutes into it, it stopped burning. The laser moves as it should, the laser is on. If functional and follows directions, just doesn’t engrave. I tried closing it out, coming back in with a different svg and still the same results. I have checked connections. Not sure what else to do here.
