Machine settings tab

There’s a possibility that the pop-up for the Machine settings window is caught behind the main LightBurn screen and cause this stuck behavior. It’s more common on laptops when a second screen is used.

With LightBurn closed, hold the Shift key and start LightBurn.

This will reset the saved Window behaviors to factory defaults in LightBurn. This should not change other files or settings.

With LightBurn open, click the Machine settings to open that window.
Please confirm that the Machine settings window is presented in a way that can be accessed.
