Co2 reverse etching

My red and black 80 watt co2 is etching in mirror , can’t figure it out.
Any help is greatly appreciated.

“red and black chinese co2” as listed in your forum profile or “My red and black 80 watt co2” does not tell us much about the technical side of your setup, so I am going to take a guess.

But in most cases, choose the opposite circle to the one you currently have selected in your ‘Device Settings’ window. Click the “spanner/screwdriver” icon near the top-center of the LightBurn screen to expose.
