4. Nastavení

4.1. Vybalení a umístění

1. Opatrně vyjměte stroj z obalu. Uschovejte si veškerý obalový materiál pro případnou budoucí přepravu.
2. Place the laser engraver on a stable, level surface capable of supporting its weight. Ensure sufficient clearance around the machine for ventilation and access.
3. Install the included honeycomb and blade workbeds as required for your specific application.

4.2. Connecting the Water Chiller

A water chiller is essential for cooling the CO2 laser tube. Proper cooling prevents overheating and extends the tube's lifespan.

1. Fill the water chiller with distilled water or a recommended coolant solution.
2. Connect the chiller's inlet and outlet hoses to the corresponding ports on the laser engraver. Ensure connections are secure to prevent leaks.
3. Power on the chiller and verify that water is circulating properly before operating the laser.

4.3. Connecting Air Assist and Exhaust System

The air assist system helps to clear debris and reduce charring, while the exhaust system removes fumes.

1. Connect the air pump to the air assist inlet on the machine.
2. Attach the exhaust hose to the machine's exhaust port and direct it to an appropriate external ventilation system.

4.4. Připojení napájení
