3. Configuració

Proper setup is crucial for optimal performance and safety. Follow these steps to prepare your laser engraver for use:

1. Desembalatge i col·locació: Carefully unpack the machine. Place it on a stable, level surface in a well-ventilated area, away from flammable materials.
2. Connect Exhaust System: Attach the provided exhaust hose to the machine's exhaust port and route it to an external vent or a dedicated fume extractor.
3. Connect Air Assist: Connect the air assist pump to the designated port on the machine. Air assist helps to clear debris and reduce scorching during operation.
4. Connect Water Chiller: Connect the water chiller (or pump) to the laser tube's inlet and outlet ports. Ensure the chiller is filled with distilled water and operating correctly to maintain the laser tube's temperature.
5. Connexió d'alimentació: Connecteu la màquina a una presa de corrent amb terra.
6. Instal·lació de programari: Install the necessary software (RDWorks, LightBurn, CorelDRAW, AutoCAD) on your computer and connect it to the laser engraver via USB or Ethernet.
7. Initial Alignment & Focus: While machines are often pre-aligned, it is recommended to verify mirror alignment and focal length according to the detailed instructions in the full user manual. The autofocus function will assist with setting the correct focal distance.
