Laservii-LR1 Y-axis Rotary Roller User Manual

1. Warnings & Safety Information

Fire and Burn Hazard:

• High temperatures generated during processing may ignite the workpiece, smoke, or surrounding materials.
• The processing area must be kept clear of flammable substances and equipped with fire extinguishing equipment.
• After processing, the workpiece and machine components (e.g., spindle, laser head) may remain hot for an extended period; verify full cooling before handling.

Mechanical Injury Hazard:

• High-speed rotating spindles, moving gantries, belts, and lead screws pose serious risks of crushing, cutting, or entanglement injuries.
• Before performing any installation, commissioning, cleaning, or maintenance operation, disconnect the machine from the main power supply.

Electrical Hazard:

• High-voltage circuits are present internally. Unauthorized personnel must not open the electrical control cabinet.
• All electrical connections must comply with local regulations and be performed by qualified electricians.

Hazardous Substances and Fumes:

• Processing certain materials (e.g., plastics, composites, coated metals) may generate toxic, carcinogenic, or irritating fumes and dust.
• Use only in environments equipped with an effective Local Exhaust Ventilation (LEV) system.

2. Product Setup

2.1 Preparation

• Confirm compatibility of the accessory model with your laser engraver. This rotary roller is compatible with all TWOTREES-branded machines.
• Ensure the workspace is clean and well-ventilated.

2.2 Installation

1. Power Disconnection: Shut down the host machine and unplug it from the main power source. Wait until all components—especially the laser source and spindle motor—are fully cooled.
2. Removal of Old Component (if applicable): Refer to the original manufacturer's manual for your laser engraver. Record existing wiring connections and mechanical positioning, then carefully remove the component to be replaced.
3. Installation of New Component: Install the new rotary roller accessory in reverse order of removal. Ensure all mechanical connections are securely tightened and all electrical connections are correct, properly polarized, and firmly secured.

The Laservii-LR1 Rotary Roller is designed for plug-and-play installation, with 100% pre-installed components for ease of use.

3. Operating Instructions

3.1 Calibration

After installation, recalibrate the relevant systems (e.g., laser power, tool length, engraving area) as specified in your laser engraver's original manufacturer's manual.

3.2 Testing

Conduct a low-power/low-speed no-load test under safe conditions to verify smooth operation, absence of abnormal noise, and absence of alarms before resuming normal use.

3.3 Engraving Cylindrical Objects

The Laservii-LR1 Rotary Roller is designed to engrave a wide variety of cylindrical objects, including cans, wine bottles, cups, and curved crafts. Place your cylindrical workpiece stably on the rotary roller and rotate it smoothly through compatible software like LightBurn.

4. Maintenance

• Keep the rotary roller clean and free from dust and debris.
• Regularly inspect belts and rollers for wear and tear.
• Ensure all connections remain secure.

5. Troubleshooting

• Engraving inconsistencies: Check calibration settings in your laser engraver software. Ensure the workpiece is securely placed and not slipping.
• Unusual noise/vibration: Inspect belts for proper tension and alignment. Verify all mechanical connections are tight.
