Connection issues between your computer and the Ray5 MiniS can prevent proper control of the machine and interrupt engraving tasks. These issues are usually related to drivers, port conflicts, baud rate settings, or incorrect software configuration rather than hardware failure.
This guide provides a structured troubleshooting process to help you quickly restore a stable connection using LightBurn or LaserGRBL.
1) Can't find CH340 driver
For Windows systems, it needs to right-click the computer and select Manage, click Device Manager, click to expand Ports (COM & LPT), find the port corresponding to the CH340 driver, and then select this port in LightBurnor LaserGRBL.
For MacOS, please go to About this Mac > Overview > System Report, select USB under Hardware (there will be USB Serial if the driver is installed automatically), and select the cu.wchusbserial14230 port in LightBurn or LaserGRBL.
If no ports are listed in the expanded Ports (COM & LPT), it means that no engravers were found, which could mean that it is not plugged in correctly, isn't powered, or the PC is missing a driver. It needs to download the CH340 driver from the link and double-click it to install:
Before connecting, please make sure that the CH340 port is not occupied by software such as serial communication tools, cura, etc.
3) The Baud rate setting error
The baud rate should be set to 115200. The wrong baud rate will cause the connection to the engraving machine to fail.
4) The configuration fileis not imported or damaged
For LightBurn, click "Devices"in the laser control moduletoimportthe engraver. Click ‘Import,’ select the RAY5 mini.lbdevfile, and click OK to add the RAY5 miniconfiguration to LightBurn.The macro commands will be successfully added in the Console window, and RAY5 minidevice will appear in the list of devices to the right of the 'Devices' button in the Laser window when the configuration file is imported successfully.
Conclusion
Most connection issues with the Ray5 MiniS are caused by driver installation problems, incorrect port selection, or improper software settings. By verifying the CH340 driver, ensuring the correct COM port, setting the baud rate to 115200, and importing the correct configuration file, you can quickly restore stable communication between your computer and the engraving machine.
Maintaining proper connection setup ensures reliable control and smooth engraving performance.

Item was larger than expected but in good order. Arrived on time and package was undamaged. Build is still pending, will comment further when completed
Good morning, I'm happy with my choice of the RAY5 5W engraver, which is excellent for my needs, but I'm frustrated and disappointed with the technical support. I can't figure out what's going on. 14 days after the engraver arrived, I still can't turn it on. They told me that during this New Year's Eve period, everything shuts down. Today, February 24th, I hope you can help me resolve my issue. I hope to hear from you soon.
