SCULPFUN Rotary Roller Auxiliary Kit for Laser Engravers

1. Introduction

The SCULPFUN Rotary Roller is an auxiliary kit designed to enhance the capabilities of your laser engraver, specifically for engraving cylindrical and round objects. This device allows for precise 360-degree rotation of items such as cans, glass bottles, pens, cups, and other similar containers, ensuring even and complete engraving patterns. The kit includes four raise feet to adjust the height of your laser engraving machine, accommodating the rotary roller effectively.

This manual provides detailed instructions for the proper setup, operation, and maintenance of your Rotary Roller to ensure optimal performance and longevity.

4. Setup

4.1 Assembly and Connection

The SCULPFUN Rotary Roller comes pre-assembled, requiring minimal setup before use. The primary steps involve connecting it to your laser engraver and, if necessary, attaching the raise feet.

1. Attaching Raise Feet: If your laser engraver requires additional height to accommodate the Rotary Roller, attach the four provided raise feet to the corners of your laser engraver's frame. Secure them using the screws and nuts from the screw bag. Ensure the anti-slip rubber pads are applied to the bottom of the feet for stability.
2. Connecting the Rotary Roller: Locate the Y-axis motor cable on your laser engraving machine. Disconnect the original Y-axis motor cable. Connect the provided Rotary Roller cable (Type A or B, depending on your engraver model) to the Y-axis motor port on your laser engraver. Then, plug the other end of the Rotary Roller cable into the Rotary Roller unit.

4.2 Adjustments

The Rotary Roller features an easy-to-use sliding adjustment mechanism for different object diameters.

• Roller Spacing Adjustment: To adjust the space between the two rubber rollers, simply slide the movable roller assembly along the base. Once the desired spacing is achieved for your cylindrical object, fix it in place by hand-tightening the knob. This design is faster and simpler than traditional multi-stage fixing hole adjustments.
• Belt Tightness: The belt tightness can be adjusted using the hand screw. Ensure the belt has appropriate tension for smooth operation without slippage.
• Engraving Diameter Range: The Rotary Roller supports engraving cylindrical objects with diameters ranging from 6mm to 150mm. The thinner body and clever raising feet contribute to this larger engraving diameter range.

5. Operating Instructions

5.1 Software Compatibility

The SCULPFUN Rotary Roller is compatible with various laser engraving software, including LightBurn and LaserGRBL. It supports Windows and Mac OS systems. No specific software parameter settings are required for the Rotary Roller itself, as its surface linear velocity is designed to match the original Y-axis speed of compatible laser engravers.

5.2 Engraving Process

Once the Rotary Roller is connected and your laser engraver is powered on, you can begin engraving cylindrical objects.

1. Place the Object: Carefully place the cylindrical object you wish to engrave onto the Rotary Roller, ensuring it is stable and centered.
2. Prepare Design in Software: Open your engraving software (e.g., LightBurn) and load your desired design. Adjust the design's dimensions to match the circumference and height of your object. For example, if a bottle has a circumference of 205mm, set the picture height in the software to 205mm for a 1:1 original scale engraving.
3. Start Engraving: Initiate the engraving process from your software. The Rotary Roller will automatically rotate the object as the laser engraves, creating a seamless design around its surface.

The high-friction 70A rubber shaft prevents slippage, ensuring consistent and accurate engraving results.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your SCULPFUN Rotary Roller.

• Cleaning: Periodically clean the rubber rollers and the main body of the Rotary Roller to remove any dust, debris, or engraving residue. Use a soft, dry cloth. Avoid abrasive cleaners or solvents that could damage the materials.
• Belt Inspection: Check the drive belt for any signs of wear, cracks, or looseness. If the belt appears worn or stretched, it may need to be replaced. Ensure the belt tension is appropriate as described in the Setup section.
• Storage: When not in use, store the Rotary Roller in a clean, dry environment away from direct sunlight and extreme temperatures.

7. Troubleshooting

If you encounter issues with your Rotary Roller, refer to the following common problems and solutions:

• Object Slippage: If the cylindrical object is slipping on the rollers, ensure the roller spacing is correctly adjusted for the object's diameter. Check the rubber rollers for cleanliness and wear. Increase belt tension if necessary.
• Uneven Engraving: Uneven engraving can be caused by incorrect object placement, loose belt tension, or an unstable setup. Verify the object is centered and stable, check belt tension, and ensure the laser engraver and Rotary Roller are on a firm, level surface.
• Rotary Roller Not Moving: Check all cable connections between the Rotary Roller and the laser engraver's Y-axis motor port. Ensure the laser engraver is powered on and the software is sending commands correctly.
• Software Not Recognizing Rotary: The Rotary Roller functions by replacing the Y-axis movement. Ensure your laser engraver's software is configured for Y-axis control and that the Rotary Roller is correctly connected. No special software settings are typically needed for the Rotary Roller itself.
