Official setup video for the VEVOR 50W Laser Engraver.
- Unpack and Verify Accessories: Carefully unpack the machine and all included accessories. Refer to the 'Package Contents' section to ensure all items are present.
- Install Exhaust Fan and Smoke Pipe: Attach the smoke fan to the designated exhaust port on the machine. Connect the flexible smoke pipe to the fan and direct it to an appropriate ventilation outlet.
- Install Air Pump: Connect the air pump to the air assist inlet on the machine. Ensure the tubing is securely attached.
- Install Water Pump: Place the water pump in a container filled with distilled water. Connect the water inlet and outlet tubes from the machine to the water pump, ensuring proper circulation for the laser tube cooling system.
- Connect USB Cable: Connect one end of the USB cable to the laser engraver and the other end to your computer (laptop or desktop).
- Insert Encryption Lock (USB Key): Insert the provided USB encryption lock into an available USB port on your computer. This is often required for the software to function correctly.
- Connect Power Cord: Plug the power cord into the machine's power inlet and then into a suitable electrical outlet.
- Remove Guide Rail Screws: Locate and remove any screws or fasteners that secure the laser head's guide rail for shipping. This allows the laser head to move freely.
6. Operating Instructions
After completing the setup, follow these steps to operate your laser engraver:
- Power On: Turn on the main power switch on the machine.
- Emergency Stop: Ensure the emergency stop button is disengaged (pulled out) before starting.
- Safety Lock: Ensure the safety lock is in the 'unlocked' position.
- Software Installation: Install the provided CorelDRAW software (or compatible alternative) on your computer. Follow the software's installation guide.
- Design and Prepare: Create or import your design in the software. Adjust settings such as power, speed, and resolution according to your material and desired outcome.
- Material Placement: Place the material to be engraved or cut on the working table, ensuring it is flat and secure.
- Focus Adjustment: Adjust the laser head's focus according to the material thickness.
- Start Engraving/Cutting: Initiate the engraving or cutting process from the software. Monitor the machine during operation.
- Lighting System: Use the LED light switch to illuminate the working area for better visibility.
- Power Off: After use, turn off the laser power switch, then the main power switch.
7. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your laser engraver:
- Clean Optics: Regularly clean the laser lens and mirrors with appropriate cleaning solutions and lint-free wipes to maintain laser beam quality.
- Water Cooling System: Periodically check the water level in the cooling reservoir and replenish as needed. Replace the water every few weeks to prevent algae growth and maintain cooling efficiency. Ensure the water pump is free from blockages.
- Clean Working Area: Keep the engraving area and exhaust system clean from debris and residue to prevent fire hazards and ensure efficient smoke extraction.
- Lubricate Moving Parts: Apply a small amount of lubricant to the guide rails and moving parts as recommended in the detailed manual to ensure smooth operation.
- Laser Tube Inspection: Inspect the CO2 laser tube for any signs of damage or degradation. A 50W laser tube typically has a service life of approximately 2000 hours.
8. Troubleshooting
Here are some common issues and their potential solutions:
- Machine Not Powering On: Check the power cord connection, ensure the main power switch is on, and verify that the emergency stop button is disengaged.
- Laser Not Firing: Ensure the laser tube is properly connected and cooled. Check software settings for laser power and enable status. Verify the safety lock is disengaged.
- Poor Engraving/Cutting Quality: Adjust laser focus, power, and speed settings. Clean the laser lens and mirrors. Ensure the material is flat and stable on the workbed.
- Software Connection Issues: Verify the USB cable is securely connected to both the machine and the computer. Ensure the USB encryption lock is inserted. Reinstall software drivers if necessary.
- Excessive Smoke/Fumes: Check that the smoke fan and pipe are properly installed and unobstructed. Ensure adequate room ventilation.
9. User Tips
- Software Compatibility: While the machine supports CorelDRAW, some users inquire about LightBurn. Always verify software compatibility with the manufacturer or through official documentation before purchasing third-party software.
- Material Testing: When working with new materials or thicknesses (e.g., plywood), always perform small test cuts or engravings on scrap pieces to determine optimal power and speed settings. This helps prevent material waste and achieve desired results.
- Regular Cleaning: Consistent cleaning of the laser head, mirrors, and work area significantly improves engraving quality and extends component life.
- Water Quality: Using distilled water in the cooling system is crucial to prevent mineral buildup and extend the life of the laser tube.
