5. Operating Instructions
5.1 Software Installation and Connection
The TTS-20 Max supports various connection methods and software:
- Software: Compatible with LaserGRBL (free open-source software) and LightBurn (paid software). Install your preferred software on your computer (Windows or Mac).
- Connection Methods:
- USB Connection: Connect the machine to your computer using the provided USB cable.
- WiFi Connection: Use the dedicated mobile app or web terminal for wireless control.
- Offline Engraving: Load G-code files onto a TF card and insert it into the machine for standalone operation.

5.2 Engraving and Cutting Process
- Prepare Material: Place your material securely on the working surface. Ensure it is flat and stable.
- Adjust Focus: Use the manual lifting module to adjust the laser module's height to achieve the correct focal length for your material.
- Load Design: Open your chosen software (LaserGRBL or LightBurn) and load your design file (Nc, Dxf, Bmp, Jpg, Png, Gcode).
- Set Parameters: Adjust laser power, speed, and passes according to your material and desired effect. Refer to the software's documentation for detailed parameter settings.
- Start Operation: Initiate the engraving or cutting process from the software or directly from the machine if using offline mode.

5.3 Metal Color Engraving
The TTS-20 Max can create vibrant colors on metal surfaces through instant metal oxidation. Experiment with different power settings and line intervals to achieve various color effects. The color chart in the image below serves as a reference.

6. Maintenance
- Cleaning: Regularly clean the laser lens and the working area to ensure optimal performance and prevent debris buildup. Use a soft, lint-free cloth and appropriate cleaning solutions if necessary.
- Lubrication: Periodically lubricate the guide rails and moving parts to ensure smooth motion.
- Belt Tension: Check the tension of the synchronous belts. Adjust the tensioner if the belts are too loose or too tight to maintain motion stability.
- Laser Module Inspection: Inspect the laser module for any signs of wear or damage. Ensure the air assist nozzle (if installed) is clear.
7. Troubleshooting
- Laser Not Firing: Check power connection, laser module connection, and ensure safety features (like limit switches) are not engaged. Verify software settings for laser power.
- Poor Engraving/Cutting Quality: Adjust focus, laser power, speed, and number of passes. Ensure the material is clean and flat. Check for debris on the laser lens.
- Machine Not Connecting: Verify USB cable connection or WiFi settings. Ensure correct drivers are installed for USB. Restart the machine and computer.
- Abnormal Movement: Check belt tension and ensure all moving parts are free from obstruction. Inspect guide rails for damage or debris.
- Software Issues: Ensure you are using the latest version of LaserGRBL or LightBurn. Consult the software's documentation or community forums for specific issues.
