For Windows users, right-click This PC, select Manage, and open Device Manager. Expand the Ports (COM & LPT) section to locate the CH340 driver. Identify the COM port assigned to your Ray5 Mini and select it from the port list in LaserGRBL. Set the baud rate to 115200, then click Connect.

1) Connecting the Ray5 Mini to LaserGRBL

Once connected, the GRBL firmware will respond with a “welcome message” indicating the firmware version. You’ll also see “Status: Idle” displayed in the lower-right corner of the LaserGRBL interface — confirming a successful connection.

For macOS users, navigate to About This Mac → Overview → System Report, then click USB under the Hardware section. If the driver has installed automatically, you’ll find “USB Serial” listed under connected devices.

If no COM port appears in the dropdown list, it means the engraver was not detected. This could be due to an unplugged USB cable, the engraver being powered off, or a missing driver. To fix this, go to Tools → Install CH340 Driver within LaserGRBL to install the necessary driver.

2) Creating and Engraving a Project in LaserGRBL

Once the Ray5 Mini is properly connected, you can start setting up your engraving project.
Click File → Open File to import the image or design you want to engrave. Set the quality to 10 lines/mm, then click Next. Refer to your material’s parameter chart to define the optimal engraving power (S-MAX) and speed.

Make sure to select M4 – Dynamic Power Mode for laser operation.

💡 Tip: The S-MAX value should be 10 times the target laser power.

• For 100% laser power, set S-MAX = 1000

• For 60% power, set S-MAX = 600

Next, resize your image to fit the desired engraving area. If the design extends beyond the workspace, you can fine-tune its position using XY offset adjustments.

After importing the file and configuring parameters, use the focusing block to set the correct laser focus distance on the Ray5 Mini. Then, click the Frame button to confirm the engraving position on your material. Finally, press Start to begin the engraving process.

Additional Tips for Stable Engraving

• Always check that your engraving surface is level and clean before starting.

• Ensure the laser module lens is free of dust or debris for consistent output.

• Save your preferred engraving profiles in LaserGRBL for faster setup in future projects.

By following these steps, you can achieve precise, high-quality results with your Ray5 Mini laser engraver using LaserGRBL software — whether for DIY creations, small-scale production, or detailed material testing.
