2. Configuración e instalación
The ATOMSTACK R8 Rotary Chuck is designed for immediate use with minimal setup. It features a high-strength aluminum alloy structure that requires no complex assembly out of the box.
2.1 Colocación inicial
Place the rotary chuck on a stable, level surface within your laser engraving machine's working area. Ensure there is sufficient clearance for the object to be engraved and for the laser module to move freely.
2.2 Conexión al grabador
To integrate the rotary chuck with your engraving machine, simply replace the Y-axis terminal of your engraver with the rotary chuck's connection. This creates a seamless connection, allowing the engraver's software to control the rotary motion.

2.3 Adjusting Height with Foot Pads
The package includes four 100mm high foot pads. These are used to raise your laser engraving machine, ensuring proper alignment and clearance when working with the rotary chuck, especially for larger or taller objects. Position these pads securely under the corners of your engraving machine.
2.4 Configuración de software
Before operating, it is crucial to change the configuration parameters within your laser engraving software (e.g., LaserGRBL, LightBurn) to recognize and properly control the rotary chuck. Refer to your software's specific documentation for detailed instructions on rotary axis setup.
3. Instrucciones de funcionamiento
The ATOMSTACK R8 Rotary Chuck is designed for precise engraving on various cylindrical and irregular objects. Follow these guidelines for optimal performance.
3.1 Carga de materiales
The chuck's jaws are easily adjustable without tools. Securely clamp your cylindrical object (e.g., tumblers, pens, bottles) into the chuck. Ensure the object is centered and firmly held to prevent slippage during engraving.

3.2 Grabado de objetos irregulares
For irregular cylindrical objects like wine bottles or uniquely shaped containers, the R8 Rotary Chuck offers an adjustment angle of up to 180° and a 360° rotation capability. This flexibility allows you to position the object optimally for engraving, ensuring the laser can reach all necessary surfaces.

4. Mantenimiento
To ensure the longevity and optimal performance of your ATOMSTACK R8 Rotary Chuck, regular maintenance is recommended.
- Limpieza: Periodically clean the chuck jaws and the main body of the rotary chuck to remove any dust, debris, or material residue from engraving. Use a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the finish or internal components.
- Inspección: Regularly inspect the moving parts, such as the chuck mechanism and rotation components, for any signs of wear or damage. Ensure all screws and fasteners are secure.
- Lubricación: If any moving parts feel stiff or noisy, a small amount of light machine oil can be applied to the appropriate points, taking care not to over-lubricate or get oil on electrical components.
- Almacenamiento: Cuando no esté en uso, guarde el mandril giratorio en un entorno limpio y seco, alejado de la luz solar directa y de temperaturas extremas.
