5. Setup

5.1 Initial Placement

Place the NEJE R5 Rotary Roller on a stable, level surface within the working area of your laser engraver. Ensure there is enough clearance for the laser module to move freely over the entire length of the rotary roller and the object to be engraved.

5.2 Connecting to the Laser Engraver

The R5 Rotary Roller connects to your laser engraver's A-axis port. Refer to your laser engraver's manual for the exact location of this port. Typically, it's a dedicated port for rotary attachments or an interchangeable axis port.

• Turn off and unplug your laser engraver.
• Locate the A-axis or rotary attachment port on your laser engraver's control board.
• Connect the provided cable from the R5 Rotary Roller's stepper motor to the corresponding port on your laser engraver.
• Ensure the connection is secure.
• Plug in and power on your laser engraver.

Note: Some laser engravers may require specific firmware settings or software configuration to enable rotary engraving. Consult your laser engraver's documentation for details.

5.3 Adjusting for Cylindrical Objects

The R5 Rotary Roller is designed to accommodate various cylindrical and irregularly shaped objects. Adjustments involve the chuck jaws and the tailstock position.

5.3.1 Chuck Jaw Adjustment

The chuck jaws can be adjusted to securely hold objects of different diameters.

This diagram shows how to adjust the chuck jaws by twisting the chuck body to the left, allowing the jaws to expand or contract. The arrows indicate 180-degree rotation for adjustment.

A closer look at the chuck jaws, illustrating the twisting motion required to open or close them for securing an object.

• To open the chuck jaws, twist the chuck body to the left (counter-clockwise).
• To close the chuck jaws and clamp an object, twist the chuck body to the right (clockwise).
• Ensure the object is centered and held firmly by the jaws. Do not overtighten, as this may damage the object or the chuck.

This image demonstrates how the chuck jaws securely hold a cylindrical object in place for engraving.

5.3.2 Tailstock Position Adjustment

The tailstock can be moved along the base to support objects of varying lengths.

The diagram illustrates the tailstock's ability to slide along the base plate, allowing adjustment for different object lengths. The arrow indicates the direction of movement.

• Loosen the securing screws on the tailstock.
• Slide the tailstock along the base rails until it provides adequate support for the object.
• Ensure the object is level and centered between the chuck and the tailstock rollers.
• Tighten the securing screws to fix the tailstock in position.

6. Operation

6.1 Placing the Object

• Adjust the chuck jaws and tailstock to fit your cylindrical object (refer to Section 5.3).
• Carefully place the object into the chuck, ensuring it is centered.
• Secure the object by tightening the chuck jaws and adjusting the tailstock for stable support.
• Verify that the object can rotate freely without obstruction.

6.2 Software Configuration

Before engraving, you will need to configure your laser engraving software (e.g., LightBurn, LaserGRBL) to work with the rotary attachment. Key settings typically include:

• Enable Rotary: Activate the rotary axis function in your software.
• Steps per Rotation: This value depends on the stepper motor and micro-stepping settings. You may need to calibrate this for accurate rotation.
• Roller Diameter/Object Diameter: Input the diameter of the object you are engraving.
• Axis Mapping: Ensure the software's rotary axis (usually A or Y) corresponds to the physical connection.

Refer to your laser engraving software's documentation or online resources for specific rotary setup instructions.

6.3 Engraving Process

• Create or load your design in the laser engraving software.
• Adjust laser power, speed, and passes according to the material and desired effect.
• Perform a test run (e.g., low power outline) to verify alignment and focus.
• Start the engraving process. Monitor the operation closely.

7. Maintenance

• Cleaning: Regularly clean dust and debris from the rotary roller, especially around the chuck jaws, rollers, and stepper motor. Use a soft brush or compressed air.
• Lubrication: Periodically apply a small amount of light machine oil to the moving parts, such as the chuck mechanism and tailstock rails, to ensure smooth operation.
• Inspection: Check for any loose screws or worn parts. Tighten as necessary.
• Storage: When not in use, store the rotary roller in a clean, dry environment to prevent corrosion and damage.

8. Troubleshooting

9. Specifications

10. User Tips

• Calibration is Key: Always perform a rotary calibration in your software to ensure accurate "steps per rotation" for your specific setup. This prevents distorted engravings.
• Secure Connections: Double-check all cable connections before each use to avoid intermittent operation.
• Test Engravings: Before committing to a final project, always perform a small test engraving on a similar scrap material to fine-tune settings and verify alignment.
• Object Stability: Ensure the cylindrical object is perfectly stable and cannot wobble or slip during rotation. Use the tailstock support diligently.
• Software Compatibility: Confirm that your laser engraving software fully supports A-axis rotary attachments and that you have the latest drivers/firmware for your engraver.

11. Warranty and Support
