2. Safety Information
Always prioritize safety when operating laser equipment and accessories. This rotary module works in conjunction with a laser engraver, which emits concentrated laser radiation that can cause serious injury or damage if not handled properly.
- Eye Protection: Always wear appropriate laser safety glasses that are rated for the wavelength of your laser during operation.
- Ventilation: Ensure adequate ventilation in your workspace to dissipate fumes and smoke produced during engraving.
- Flammable Materials: Keep flammable materials away from the laser's path.
- Supervision: Never leave the laser engraver and rotary module unattended during operation.
- Power Off: Disconnect power to both the laser engraver and the rotary module before performing any maintenance or adjustments.
- Refer to your primary laser engraver's user manual for comprehensive safety guidelines specific to your machine.

4. Setup
The Genmitsu Rotary Roller V2 is designed for easy, tool-free setup.
4.1 Physical Installation
- Place the rotary module on a stable, flat surface beneath your laser engraver's working area.
- Adjust the roller distance to accommodate the diameter of the object you intend to engrave. This can be done without tools by sliding the adjustable end of the rotary. The adjustable range is from 19mm to 76mm, with 16 distinct positions.
- For stemmed objects like wine glasses, attach the Y-brace roller to provide additional support and stability.

4.2 Electrical Connection
Connect the rotary module to your laser engraver using the provided wire. The rotary module features a PH2.0-6P (6 PIN) port, which connects to the XH2.54-4P (4 PIN) port on your laser engraver. Ensure the correct cable is used for your specific machine model.
The Genmitsu Rotary Roller V2 is compatible with most laser engravers and laser cutters on the market, including Genmitsu 3018-Pro, 3018-Prover, 3020-Pro Max, 4040-PRO, 4040 Reno, Jinsoku LC-50 PLUS, LC-60A, LE-1620, and LE-5040 Laser Engravers. For non-Genmitsu machines, verify the port on your machine first. If you are unsure, contact Genmitsu support.

4.3 Software Configuration
After physical connection, you will need to configure your laser engraving software (e.g., LaserGRBL, LightBurn) to recognize and control the rotary axis. This typically involves enabling the rotary axis function and setting the correct steps per millimeter for rotation. Consult your software's documentation for detailed instructions on rotary axis setup.
5. Operating Instructions
5.1 Material Placement
Carefully place the cylindrical object onto the rollers. Ensure it sits securely and is centered. The polyurethane coating on the rollers provides an improved grip, minimizing slipping during engraving. The rotary supports material diameters from 5mm to 160mm and lengths from 10mm to 195mm.

5.2 Engraving Process
- Once the object is securely placed and the software is configured, load your engraving design.
- Perform a test run or frame the engraving area to ensure correct positioning and alignment.
- Initiate the engraving process from your laser software. The rotary module will precisely rotate the object as the laser engraves, creating a seamless design around the cylindrical surface.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Genmitsu Laser Rotary V2.
- Cleaning: Periodically clean the rollers and the module's frame to remove dust, debris, and engraving residue. Use a soft, dry cloth. Avoid abrasive cleaners that could damage the polyurethane coating.
- Inspection: Inspect the rollers and belts for any signs of wear or damage. Ensure the rollers spin freely and the belt tension is appropriate.
- Storage: When not in use, store the rotary module in a clean, dry environment to prevent dust accumulation and potential damage.
