Operating Instructions
Selecting and Attaching Grippers
The Mecpow G5 Rotary Roller includes three types of grippers to accommodate various object shapes:
- Trapezoidal Clamp (Ladder Jaws): Suitable for general cylindrical objects.
- Square Clamp: Used for internal and external clamping of various objects.
- Stud Clamp: Ideal for rings, bracelets, and other circular objects with a diameter of 10-85mm.
Choose the appropriate gripper set for your object and securely attach it to the rotary chuck.

Adjusting the Angle
The rotary module allows for a 90° adjustable angle, enabling engraving on unique objects such as beverage cans, baseballs, and goblets. Use the angle lines on the module for precise calibration.

Securing the Object
Place the object firmly within the selected grippers. Ensure the object is centered and stable to prevent movement during engraving. For objects of different lengths and sizes, adjust the position of the supporting column to provide optimal stability.

Maintenance
Cleaning
Regularly clean the rotary roller module and grippers to remove dust, debris, and engraving residue. Use a soft, dry cloth. Avoid abrasive cleaners or solvents that could damage the finish.
Lubrication
Periodically check moving parts for smooth operation. Apply a small amount of appropriate lubricant if necessary, following general guidelines for precision mechanical components.
Storage
When not in use, store the rotary roller in a clean, dry environment to protect it from dust and moisture.
Troubleshooting
Common Issues and Solutions
- Issue: Engraving is distorted or incorrect on the Y-axis.
Possible Cause: Incorrect Y-axis step control variable in engraving software.
Solution: In software like LightBurn, ensure the Y-axis step control variable ($100) is correctly configured for the rotary roller. A common error in some manuals incorrectly advises changing $101. Always adjust $100 for Y-axis rotary control. The formula is typically 1000 / D (where D is the diameter of your object to engrave). - Issue: Object not securely held.
Possible Cause: Incorrect gripper selection or improper adjustment.
Solution: Ensure the correct gripper type (trapezoidal, square, or stud) is selected for the object's shape and size. Adjust the grippers firmly to secure the object without excessive force. - Issue: Rotary module not recognized by engraving machine.
Possible Cause: Incorrect cable connection or software settings.
Solution: Verify that the correct cable (white for Mecpow, black for others) is securely connected to the Y-axis port. Check software settings to ensure the rotary axis is enabled and configured.
