Hello new to this! Port failed to open- already in use? This happens sometimes when I stop a project, usually if I restart the laser and LightBurn it will work. This time it’s not working, what can I do?
After closing LightBurn, restarting your laser, and then re-opening LightBurn, you may need to manually select the appropriate COM port from the drop down menu in the laser window:
You’ll see a response in the Console window when you’ve selected the correct COM port.
If it’s still not working, this could be a USB connection issue. Try a new USB cable.
