Lightburn Wont Connect

You may need to close LightBurn, turn your laser off and on again, restart LightBurn, and then manually select the correct COM port from the drop down menu in the Laser window.

You’ll see a response in your ‘Console 1’ window when you’ve selected the correct port.
If you’re still unable to connect, make sure your USB connection is firmly seated, and try a different, higher quality USB. If you’re using any USB hubs or extenders, take them out of line.
