How to Use TF Card Offline Mode for Engraving

The Longer Ray5 desktop laser engraver offers multiple control options for your engraving projects. One convenient method is to use the TF card in offline mode, allowing you to run engraving tasks without connecting the machine to a computer. This mode is ideal for workshops, makerspaces, or portable setups where a PC connection may not be practical.

Step 1: Prepare the G-Code File

First, design your engraving pattern in software such as LightBurn. Once your design is ready, export it as a G-code file in .gc or .nc format. Save this file directly to your TF card.

Step 2: Insert the TF Card and Select File

Insert the TF card into the Ray5 control box, then navigate to the File menu to view the list of files stored on the card. Select the G-code file you just saved to enter the engraving preparation interface.

Step 3: Frame and Start Engraving

Use the Frame function to confirm the engraving area, ensuring it aligns properly with your material. Once you are satisfied, click Engrave to start the offline engraving process. The machine will execute the job directly from the TF card, without needing a connected PC.

Tips for Successful Offline Engraving

• Ensure your TF card is formatted correctly and has enough storage for your G-code files.
• Always use the Frame feature to preview the engraving area to avoid wasting material.
• Keep backup copies of your G-code files on a computer or cloud storage.
• Place the Longer Ray5 laser cutter and engraver on a stable surface to prevent tilting during operation.

Using TF card offline mode on the Longer Ray5 desktop laser engraver is a convenient, efficient, and safe way to complete engraving projects without a computer connection.
