Lasder will pulse but LightBurn not firing the laser

Sounds like a hardware failure.

The complete system is digital, so the chances of this occurring are not very good.

I’d double check your tube for it’s resonating or TEM mode. If it’s not TEM00 then you need a new tube.

Lightburn and the controller generally work or not, but don’t fail in this manner.
