I’m brand new to the laser and lightburn. We received our laser last week Xtool D1 Pro , hooked it up, downloaded lightburn and connected without a problem. Tried a few tests. We shut down, and today we tried to connect to it again, and it will not connect. There is only 1 com option, Com 1 and that is selected. Everything is up to date, I literally just downloaded and updated everything. I’ve tried uninstalling and reinstalling, but absolutly nothing. Any ideas?

      Try this:
1. Confirm that the COM port is being created/removed in Device Manager when you plug/unplug the device. Note the COM number.
2. Make sure XCS is not running.
3. In LightBurn, make sure the corresponding port identified in the first step is selected in Laser window
If that doesn’t work can you take a full screenshot of LightBurn with Console and Laser windows showing?
Also a screenshot of Edit->Device Settings window.
