4. Assembly and Setup

4.1. Unpacking

Carefully unpack all components and verify against the packing list. Ensure no parts are missing or damaged. Keep all packaging materials until assembly is complete and the machine is confirmed to be working.

4.2. Assembling the 600x600mm Expansion Kit

This section details the process of integrating the expansion kit with your existing Twotrees laser engraver frame. The general steps involve replacing the original frame profiles and belts with the longer components provided in the kit.

1. Disassemble Original Frame: Carefully remove the existing aluminum profiles and belts from your laser engraver. Refer to your engraver's original manual for specific disassembly instructions.
2. Install New Profiles: Attach the longer aluminum profiles from the expansion kit to the engraver's gantry and base, ensuring they are securely fastened.
3. Install Extended Belts: Route and tension the new, longer timing belts according to the engraver's design. Proper belt tension is crucial for engraving accuracy.
4. Secure Connections: Double-check all screws and connections to ensure the frame is rigid and stable.
5. Cable Management: Organize and secure any extended cables to prevent interference with moving parts.

4.3. Initial Connection

• Power Connection: Connect the power adapter to the engraver and a suitable power outlet.
• USB Connection: For wired control, connect the engraver to your computer via a USB cable.
• Wi-Fi Setup: Follow the instructions in the separate Wi-Fi setup guide to connect your engraver to your network for wireless control via mobile app or computer web interface.

5. Operation

5.1. Software Compatibility

The TTS-55 Pro is compatible with two primary software applications:

• LaserGRBL: A free, open-source software primarily for Windows (XP/7/8/10). It is suitable for beginners and basic engraving tasks.
• LightBurn: A paid, professional-grade software compatible with Windows, macOS, and Linux. It offers advanced features for both engraving and cutting.

Ensure you download and install the latest version of your chosen software from the official websites.

5.2. Engraving and Cutting Process

1. Material Preparation: Place your material securely on the working surface. Use clamps if necessary to prevent movement.
2. Focus Adjustment: Adjust the laser focus according to the material thickness. The TTS-55 Pro has a short 23mm focal length for optimal performance.
3. Software Setup: Load your design file into LaserGRBL or LightBurn. Configure parameters such as laser power, speed, and number of passes based on your material and desired outcome.
4. Frame and Preview: Use the software's framing function to preview the engraving area on your material. Adjust the material position if needed.
5. Start Operation: Ensure all safety precautions are in place (e.g., wearing safety goggles, proper ventilation). Initiate the engraving or cutting job from the software.
6. Monitoring: Supervise the machine throughout the operation. Be prepared to use the emergency stop if any issues arise.

5.3. Air Assist System

The TTS-55 Pro includes a metal air-assisted nozzle. Connecting an external air pump (not included) to this nozzle can significantly improve cutting performance by clearing debris and smoke from the cutting path, resulting in cleaner edges and deeper cuts. It also helps reduce charring on materials.

6. Maintenance

• Laser Lens Cleaning: Regularly clean the laser lens with a soft, lint-free cloth and lens cleaning solution to maintain optimal laser performance.
• Frame Cleaning: Keep the aluminum profiles and moving parts free of dust and debris.
• Belt Inspection: Periodically check the timing belts for wear and proper tension. Adjust or replace as needed.
• Firmware Updates: Check the official Twotrees website for any available firmware updates to ensure your machine operates with the latest features and improvements.

7. Troubleshooting

• Laser Not Firing: Check power connections, USB/Wi-Fi connection, and ensure the laser module is properly seated. Verify laser power settings in the software.
• Poor Engraving/Cutting Quality: Adjust laser focus, power, and speed settings. Ensure the material is flat and securely placed. Clean the laser lens.
• Connection Issues: For USB, try a different port or cable. For Wi-Fi, ensure the engraver is within range of your router and correctly configured. Restart both the engraver and your computer/device.
• Machine Not Moving: Check motor connections and belt tension. Ensure no obstructions are blocking the movement of the gantry or laser module.
