Lightburn says no Laser connected

Are you sure you have the proper driver for Lightburn? I use Ubuntu Linux, and haven’t been on a windows machine since 7, so I’m not sure what I can do here.

Try this link and maybe it will help you find the device.

Do you have an Ethernet port on the local pc you have connected to the laser?

I used usb for about a week and went to Ethernet, what a difference…

Good luck
