Hi Jeff,
You can force LightBurn to ignore ports by creating a PortExclude.txt file, which seems like it would help with your current problem.
- Go to File >> Open Prefs Folder to open LightBurn’s prefs directory
- Create a file called
PortExclude.txt - In that file, list the ports you want to exclude, exactly as they show up in the port selection drop down in LightBurn. Each port should be on its own line
- Save the file, and LightBurn will ignore the ports you’ve told it to filter out
Please let us know if this helps
