4. Configuració

The laser engraver and rotary axis are shipped in separate packages. Ensure both have arrived before proceeding.

4.1 Desembalatge i col·locació

1. Carefully remove all packaging materials. Inspect the machine for any shipping damage.
2. Place the laser engraver on a stable, level surface in a well-ventilated area.
3. Ensure sufficient space around the machine for proper airflow and access.

4.2 Water Cooling System Connection

Connect the external water pump (not included with all variants) to the inlet and outlet ports of the laser tube. Fill the water reservoir with distilled water. Ensure water circulates freely and there are no leaks. The machine has a built-in water protection sensor that prevents laser firing if water flow is insufficient.

4.3 Configuració del sistema d'escapament

Connect the exhaust hose to the machine's exhaust port and direct it to an outdoor vent or a suitable air filtration system. Proper ventilation is critical for safety and machine longevity.

4.4 Rotary Axis Installation (if applicable)

To install the rotary axis, first remove the honeycomb workbed. Place the rotary axis securely within the work area and connect its cable to the designated port on the machine. Refer to the rotary axis specific manual for detailed installation and calibration instructions.
