It looks like this has been asked in the past: Diaotu Fiber Laser - #6 by gilaraujo

You can follow the instructions here to manually install the drivers during LightBurn’s installation process - this will allow LightBurn to communicate with the laser itself. Getting the parameters for your machine is a different problem however, and I haven’t been able to find any files in a quick search.
