4. Instruções de configuração
Proper setup is crucial for the safe and effective operation of your laser engraver. Follow these general steps:
- Desembalagem: Retire cuidadosamente a máquina e todos os acessórios da embalagem. Verifique se há danos causados pelo transporte.
- Colocação: Place the engraver on a stable, level surface in a well-ventilated area, away from flammable materials. Ensure sufficient space around the machine for access and ventilation.
- Sistema de refrigeração a água: Connect the provided water pump or chiller to the laser tube's inlet and outlet ports. Fill the reservoir with distilled water. Ensure water flows freely through the system before powering on the laser.
- Sistema de exaustão: Connect the exhaust fan and ducting to the machine's exhaust port. Route the ducting to an outdoor vent or a suitable air filtration system to safely remove smoke and fumes.
- Conexão de energia: Conecte o cabo de alimentação à máquina e, em seguida, a uma tomada elétrica aterrada. Certifique-se de que a fonte de alimentação seja compatível com os requisitos da máquina.
- Instalação do software: Install the recommended laser control software (e.g., LightBurn, RDWorks) on your computer. Connect the engraver to your computer via USB or Ethernet.
- Initial Alignment (if necessary): Refer to the detailed software manual for initial laser path alignment procedures if required.
5. Instruções de operação
Once the machine is set up, follow these steps for typical operation:
- Ligar: Turn on the main power switch on the machine. Ensure the water cooling system is running.
- Colocação de Materiais: Place your material on the workbed. Use the appropriate workbed (honeycomb for cutting, blade for engraving) for your task.
- Auto-foco: Utilize the built-in autofocus function to set the correct focal distance for your material. This is typically done by pressing a dedicated button on the control panel or through the software.
- Preparação do software: Open your design software, import or create your design. Set laser parameters (power, speed, frequency) according to the material type and desired effect.
- Job Transfer: Transferir o trabalho file to the laser engraver via the software.
- Frame Test: Use the 'Frame' function on the control panel to preview the job area on your material. Adjust material position if necessary.
- Iniciar operação: Close the lid and press 'Start' on the control panel or in the software. Monitor the process closely.
- Parada de emergência: In case of any malfunction or emergency, press the red emergency stop button immediately.
