How to Connect the Machine to LightBurn via USB

1. Import Configuration File

Before using LightBurn with RAY5 miniS for the first time, you need to import the RAY5 miniSS.lbdev configuration file. Download it from the following link:

When launching LightBurn for the first time, the 'New Device Wizard' will appear. If not, click Devices in the Laser control module to manually import the engraver. Click Import, select the RAY5 miniS.lbdev file, and click OK to add the configuration to LightBurn. Once successfully imported, the macro commands will appear in the Console window, and RAY5 miniS will be listed under Devices in the Laser window.

After adding the device, it is recommended to set the speed unit to mm/min. To do this, go to Edit in the taskbar, select Settings, choose mm/min as the unit, and click OK.

2. Connect the RAY5 miniS to LightBurn

To use LightBurn, the engraver must be connected to the software first.

For Windows, right-click This PC and select Manage, then click Device Manager. Expand Ports (COM & LPT), find the port corresponding to the CH340 driver, and manually select it in LightBurn by clicking (Choose) in the Laser window.

For MacOS, go to About This Mac > Overview > System Report, then select USB under Hardware. If the driver is installed automatically, USB Serial will appear. In LightBurn, select cu.wchusbserial by clicking (Choose) in the Laser window.

If no ports are listed in the drop-down, it means no engraver was found, which could indicate that the device is not plugged in correctly, is not powered on, or the driver is missing. In that case, download the CH340 driver from the following link and install it:
