Console Message

Lightburn will display disconnected if it knows it’s lost the connection… However some grbl machine have some issues staying connected.
There is a show all in the console window and it will display whatever comes back from the machine.
I doubt it will buy you anything since Lightburn thinks it’s sending something or busy and isn’t going to get anything from the device in this state.
You can try a better usb cable and keep things as short as possible…
Sorry I’m not much help, but usb isn’t the best mode for these…
I have a fiber that uses usb, and I have no problems with it… but the grbl controllers will sometimes fail…
