Without the proper device profile, LightBurn may not communicate with your machine correctly, leading to connection or configuration issues.

This guide walks you through the complete setup process, including where to download the official configuration file, how to import it into LightBurn, how to verify the device settings, and what to do if the import doesn't work.

Quick Answer

To import a LightBurn configuration file for the LONGER Ray5 miniS:

  1. Download the Ray5 miniS.lbdev file from the LONGER firmware download page.
  2. Open LightBurn.
  3. Click Devices in the Laser control module.
  4. Click Import.
  5. Select the .lbdev file.
