New Update, no communication with laser

[MikeyH (Mike Hembrey)]

Rather than say it all again, I am providing a related link. Laser wattage is not relevant here.

Light burn port failed to open-already in use?

I would try first by trying to reinstall your laser. Reinstalling the driver may help. [Setting Up Your SCULPFUN S30 With LightBurn] if that does not help lets try other methods.
