• Connect the device to a computer via a USB cable.
• Install the necessary drivers for the device.
• Determine the machine's COM port.
• Open the GRBL control software.

Material Fixturing and Focusing

• Securely and evenly fix the workpiece onto the worktable using the provided clamps or other suitable methods.
• Adjust the laser focus precisely to the material surface for optimal engraving/cutting results.

Parameter Setup and Test Run

• Set appropriate power, speed, and pass count in the software according to the material type and thickness.
• Perform a small test run on a scrap piece of the same material to verify settings before starting the main project.

4. Operating Instructions

Starting Processing

• Close the protective cover of the machine.
• Activate the exhaust system to manage fumes and debris.
• Send the processing command from the GRBL control software.

Ending Operation

• After processing completes, wait until the device has fully stopped.
• Allow the laser head to cool down completely before handling the workpiece or machine.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your TTC3018 machine.

• Cleaning: Regularly clean the work area, lead screws, and guide rails to prevent dust and debris buildup, which can affect precision. Use a soft brush or compressed air.
• Lubrication: Periodically lubricate the lead screws and linear bearings with appropriate grease or oil to ensure smooth movement.
• Laser Lens: Gently clean the laser lens with a specialized lens cleaning solution and a lint-free cloth to maintain laser power and focus.
• Tighten Fasteners: Check and tighten all screws and fasteners periodically to ensure the machine's structural integrity.
• Software Updates: Keep your GRBL control software and drivers updated to the latest versions for improved performance and compatibility.

6. Precautions & Usage Restrictions

• Safety First: Always wear laser safety goggles (matched to 445±nm wavelength) during operation. Do not look directly into the laser beam.
• Material Restrictions: Engraving/cutting of PVC (polyvinyl chloride) and fluorinated plastics is strictly prohibited due to the release of toxic and corrosive fumes. Avoid materials that produce excessive smoke or are highly flammable without proper precautions.
• Environmental Requirements: Operate the machine in a well-ventilated area, away from flammable materials and liquids. Maintain a stable temperature and humidity.
• Device Protection: Do not operate the device at full power continuously beyond the maximum continuous duty time specified in the product manual to prevent overheating and damage.
• Prohibited Actions: Unauthorized disassembly of the laser module, electrical circuit modification, or removal of safety interlocks is strictly forbidden and will void the warranty. Do not put any part of your body on the machine while it is working.

7. Troubleshooting (FAQ)

Q1: What should I do if engraving/cutting depth is insufficient?

A: Please check the following sequentially: 1) Whether the laser focus is precisely aligned to the material surface; 2) Whether the power and speed settings are appropriate for the material. Increase power or decrease speed as needed.

Q2: Why are engraving edges unclear or charred?

A: This is typically caused by excessive power or insufficient speed. Reduce the power percentage or increase the travel speed in the software. Ensure proper focus.

Q3: Why is the device not recognized after connecting to the computer?

A: Please verify: 1) Whether the USB cable is undamaged and securely connected; 2) Whether the device's USB driver is correctly installed on your computer.

Q4: Why does the laser head emit no light?

A: Please check: 1) Whether all power connections are secure and functional; 2) Whether the “Laser Enable" option is activated in the control software.

Q5: How thick a material can be cut?

A: Cutting capability depends on laser power, material properties, and focal length. For common 3 mm basswood or acrylic sheets, the machine is capable. Thicker materials may require multiple passes or may not be suitable for cutting.
