1. Product Overview
The Monport 80mm Rotary Axis Attachment is designed to enhance the capabilities of your fiber laser engraver, allowing for precise marking and engraving on cylindrical and irregularly shaped objects. This attachment is ideal for small-batch work on various materials including metals, wood, glass, acrylic, and hard plastics.
Key Features:
- Highly Adaptable: Built for small-batch marking and engraving on metals, wood, glass, acrylic, and hard plastics. Accommodates a wide range of complex and irregular shaped objects.
- Easy to Install: Set up the proper angle and length ranges with your software interface. Draws power directly from your laser engraver, requiring only one cable for quick setup.
- No Positioning Joints Required: Calculate the path once and process your design without repeatedly rotating the object. Paths can be layered when reducing the machine allowance, perfect for roughing and other special finishes.
- Stable and Accurate: Compact ball screw and linear guide pair transmission provide high efficiency, stability, and precision. The chuck fits objects up to 80mm in diameter. Constructed with steel and aluminum for durability.

2. Setup and Installation
Follow these steps to properly set up and install your Monport 80mm Rotary Axis Attachment with your fiber laser engraver.
- Placement: Position the rotary axis attachment securely on the work surface of your fiber laser engraver. Ensure it is stable and aligned with the laser path.
- Connection: Locate the dedicated rotary axis port on your fiber laser engraver. Connect the provided cable from the rotary axis attachment to this port. Ensure the connection is firm.
- Software Configuration: Refer to your laser engraver's software manual for specific instructions on enabling and configuring the rotary axis. You will typically need to input parameters such as the object's diameter and the desired engraving angle.
- Object Mounting: Open the chuck jaws using the provided wrench. Carefully place the cylindrical object (e.g., cup, ring) into the chuck, ensuring it is centered and held firmly. Tighten the jaws evenly to secure the object without overtightening.

3. Operating Instructions
Once the rotary axis is installed and configured, you can begin engraving cylindrical objects.
- Design Preparation: Create or import your design in your laser engraver's software. Ensure the design is scaled appropriately for the circumference and length of your object.
- Parameter Settings: Adjust laser power, speed, frequency, and other engraving parameters according to the material being engraved. For rotary engraving, ensure the software's rotary function is enabled and correctly calibrated.
- Focus Adjustment: Adjust the laser focus to the surface of the object mounted in the rotary chuck. This is crucial for achieving clear and precise engraving results.
- Test Engraving: Before final engraving, perform a low-power test on a similar scrap material or an inconspicuous area of the object to verify settings and alignment.
- Start Engraving: Initiate the engraving process from your software. Monitor the process to ensure proper operation and safety.

4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your rotary axis attachment.
- Cleaning: Periodically clean the chuck jaws and the body of the rotary axis to remove dust, debris, and material residue. Use a soft, dry cloth. For stubborn residue, a mild cleaning solution can be applied to the metal parts, avoiding electrical components.
- Lubrication: Inspect moving parts, such as the chuck mechanism and any visible gears or bearings, for smooth operation. Apply a small amount of appropriate lubricant if necessary, following general guidelines for precision mechanical components.
- Inspection: Regularly check all screws and fasteners to ensure they are tight. Inspect the cable for any signs of wear or damage. Replace any damaged components immediately.
- Storage: When not in use, store the rotary axis attachment in a clean, dry environment, protected from dust and extreme temperatures.
5. Troubleshooting
This section addresses common issues you might encounter with your rotary axis attachment.
- Rotary Axis Not Responding:
- Check if the cable is securely connected to both the rotary axis and the laser engraver's port.
- Verify that the rotary axis function is enabled in your laser engraver's software.
- Ensure the laser engraver itself is powered on and functioning correctly.
- Inaccurate Engraving/Skipping:
- Confirm that the object is securely mounted in the chuck and not slipping.
- Check the software settings for correct object diameter and rotary calibration.
- Inspect the rotary axis for any obstructions or debris that might impede smooth rotation.
- Ensure the laser focus is correctly set on the object's surface.
- Unusual Noises:
- Turn off the laser engraver and inspect the rotary axis for any loose parts or foreign objects.
- Check for proper lubrication of moving parts.
