Setup Instructions
1. Connecting the MD19 Rotary Roller
The MD19 Rotary Roller Kit connects to your compatible Genmitsu engraving machine via a 4-pin to 6-pin terminal cable. Ensure your machine is powered off before making any connections.
- Locate the Y-axis motor port on your Genmitsu engraving machine.
- Connect the 4-pin end of the provided cable to the MD19 Rotary Roller.
- Connect the 6-pin end of the cable to the Y-axis motor port on your engraving machine.
- Power on your engraving machine. The MD19 should be recognized automatically by compatible software like LightBurn or Genmitsu's proprietary software for L8 and Z6.
2. Adjusting the Rolling Block Support
The rolling block supports objects of various heights and lengths. Adjust it to ensure the object is level and stable during engraving.

- To adjust the height, loosen the knob at the base of the rolling block.
- Raise or lower the support to match the height of your object.
- Tighten the knob to secure the rolling block in place.
- For extra-long items, the rolling block can be positioned to provide additional stability.
3. Setting the 4 Adjustable Width Gears
The MD19 features four gear settings to accommodate objects of different diameters. Select the appropriate gear for your object to ensure optimal contact and rotation.

- Gear 1: For objects with diameter (D) between 3mm and 40mm.
- Gear 2: For objects with diameter (D) between 9mm and 50mm.
- Gear 3: For objects with diameter (D) between 21mm and 60mm.
- Gear 4: For objects with diameter (D) greater than 60mm.
Slide the adjustment knob to select the gear that best fits the diameter of your object.
4. Preparing the Engraving Machine
For some Genmitsu machines, such as the L8, it may be necessary to raise the machine to accommodate the MD19 Rotary Roller and the object being engraved. This allows for sufficient clearance.

Operation Guide
1. Placing the Object for Engraving
Carefully place the cylindrical object onto the MD19 Rotary Roller, ensuring it rests securely on both the main rollers and the adjustable rolling block support. The object should be centered and stable to prevent movement during engraving.

2. Software Configuration
The MD19 Rotary Roller is compatible with popular engraving software such as LightBurn, as well as the software provided with Genmitsu L8 and Z6 machines. Refer to your specific software's documentation for detailed instructions on enabling and configuring rotary axis engraving.
- Ensure the rotary axis function is enabled in your software settings.
- Input the correct diameter of your object for accurate scaling.
- Adjust engraving parameters (speed, power, passes) as needed for your material.
3. Starting the Engraving Process
Once the object is secured and software settings are configured, initiate the engraving process through your machine's control interface or software. Monitor the engraving to ensure proper operation.

Maintenance
To ensure the longevity and optimal performance of your Genmitsu MD19 Rotary Roller Kit, regular maintenance is recommended.
- Cleaning: Periodically clean the rollers and the base with a soft, dry cloth to remove dust and debris. Avoid using abrasive cleaners or solvents.
- Inspection: Regularly inspect the rollers and moving parts for any signs of wear or damage. Ensure all screws and fasteners are tight.
