2. Consignes de sécurité

Operating a laser engraver involves inherent risks. Adherence to safety protocols is paramount to prevent injury and ensure safe operation. This machine is a Laser Class 2 device with 0.874 mW output power.

• Protection des yeux : Ne jamais regarder directement le faisceau laser. Toujours porter des lunettes de protection laser adaptées.
• Ventilation: Ensure adequate ventilation to remove smoke and fumes generated during engraving and cutting. The built-in air assist helps clear the workspace.
• Sécurité incendie : Gardez un extincteur à proximité. Ne laissez pas la machine sans surveillance pendant son fonctionnement, surtout lors du traitement de matériaux inflammables.
• Fonctions de sécurité automatiques : The flame-retardant viewing window allows for safe observation. The automatic cover interlock system halts laser operation if the lid is opened during a job.
• Compatibilité matérielle : Gravez ou découpez uniquement des matériaux compatibles avec les lasers CO2. Évitez les matériaux qui dégagent des fumées toxiques ou qui sont très réfléchissants.
• Sécurité électrique : Assurez-vous que la machine est correctement mise à la terre et branchée à une alimentation électrique adaptée. Ne l'utilisez pas si les câbles ou les composants sont endommagés.

4. Instructions de configuration

Proper setup is crucial for the safe and effective operation of your laser engraver. Follow these general steps:

1. Déballage: Retirez soigneusement la machine et tous ses accessoires de l'emballage. Vérifiez qu'elle n'a pas subi de dommages liés au transport.
2. Placement: 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.
3. Système de refroidissement par eau : 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.
4. Système d'échappement : 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.
5. Connexion électrique : Connect the power cable to the machine and then to a grounded electrical outlet. Ensure the power supply matches the machine's requirements.
6. Installation du logiciel : Install the recommended laser control software (e.g., LightBurn, RDWorks) on your computer. Connect the engraver to your computer via USB or Ethernet.
7. Initial Alignment (if necessary): Refer to the detailed software manual for initial laser path alignment procedures if required.

5. Mode d'emploi

Once the machine is set up, follow these steps for typical operation:

1. Mise sous tension : Turn on the main power switch on the machine. Ensure the water cooling system is running.
2. Emplacement du matériel : Place your material on the workbed. Use the appropriate workbed (honeycomb for cutting, blade for engraving) for your task.
3. Autofocus: 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.
4. Préparation du logiciel : Open your design software, import or create your design. Set laser parameters (power, speed, frequency) according to the material type and desired effect.
5. Job Transfer: Transférer le travail file to the laser engraver via the software.
6. Test de trame : Use the 'Frame' function on the control panel to preview the job area on your material. Adjust material position if necessary.
7. Démarrer l'opération : Close the lid and press 'Start' on the control panel or in the software. Monitor the process closely.
8. Arrêt d'urgence: In case of any malfunction or emergency, press the red emergency stop button immediately.
9. Éteindre: After the job is complete, power off the laser engraver and the water cooling system.

6. Entretien

Un entretien régulier garantit des performances optimales et prolonge la durée de vie de votre graveur laser.

• Nettoyage des lentilles et des miroirs : Nettoyez régulièrement la lentille et les miroirs du laser avec une solution et des lingettes de nettoyage spécialisées afin de maintenir la qualité du faisceau laser.
• Système de refroidissement par eau : Change the distilled water in the cooling system every 1-3 months, or more frequently with heavy use. Ensure the water chiller (if used) is functioning correctly.
• Nettoyage du poste de travail : Clean the honeycomb and blade workbeds to remove debris and residue that can affect material placement and laser performance.
• Système d'échappement : Inspect and clean the exhaust fan and ducting to ensure efficient removal of smoke and fumes.
• Lubrification des rails et des courroies : Periodically lubricate the guide rails and check the tension of the drive belts to ensure smooth movement of the laser head.
