1. Introduction

Laser marking technology is used in various fields such as industrial labeling, product tracking, and decorative engravings due to its high precision, efficiency, and flexibility. Dynamic laser rotary engraving enables engraving on curved workpieces through synchronized rotational movement. Controlled by software, the workpiece rotates with the aid of a rotary motor to ensure precise engraving.
Previously, conventional laser marking machines lacked a rotary function and were therefore unsuitable for certain products. For example, it is difficult to fully mark cylindrical objects like cups, bottles, or pens using only flat engraving. To meet the engraving requirements for different workpieces and angles, the use of a rotary axis is necessary. The EM-Smart Dual Desktop Laser Engraving Machine is known for its high precision and versatility, and it also supports rotary engraving. This guide will show you in detail how to install and optimally set up the rotary axis to achieve precise engraving results.

2. Introduction to the Rotary Axis

The rotary axis enables precise rotation of cylindrical or disc-shaped objects during engraving to ensure uniform marking. It is suitable for materials such as metal, glass, and wood and is commonly used for engraving water bottles, drinking glasses, axles, pipes, electronic device housings, bottle markings, dashboards, and vehicle lighting components. The EM-Smart rotary module significantly expands the functionality of your laser engraving machine and is suitable for objects with a diameter of 5–150 mm and a weight of up to 30 kg.

3. Installation Steps for the Rotary Axis

（1）Preparation:

• Ensure that the laser engraving machine is turned off and disconnected from the power supply.
• Clear the work area and ensure sufficient space is available.
• Prepare the rotary axis and connection cables and check the equipment for integrity.

（2）Mounting and Securing:

• Ensure that the rotary module is correctly installed on the EM-Smart Dual device.
• Position the rotary axis stably, parallel to the base plate and perpendicular to the laser beam direction to avoid positioning errors.
• Adjust the clamping devices to ensure that the workpiece does not slip during rotation.

（3）Connection and Software Settings:

（3.1）Connecting the Rotary Axis:

• Locate the corresponding port on the machine and securely connect the rotary axis cable.

（3.2）Adjusting Parameters in the Software:

• Start LightBurn and go to the rotary axis settings menu. Enable the "Rotary Axis" option and select the appropriate port (usually X or Y axis).
• Specify the rotation type in the software (e.g., step width, object diameter, circumference length) and adjust parameters such as rotation speed, acceleration, pulse count, and circumference distance.
• Ensure that the X and Y axes are correctly configured to avoid engraving distortions.

（4）Test Run and Adjustments:

• Perform a test engraving to check the rotation direction and speed of the rotary axis.
• Adjust the rotation step count to ensure that the engraving starting point aligns correctly with the desired position.
• Review the engraving result and correct any deviations or misalignments.

4. Optimization Tips

（1）Using the Zero Run Function:

• Long-term unidirectional rotation can affect repeat accuracy, such as causing position shifts or misalignments. Therefore, enable the zero run function to ensure engraving precision..

（2）Alignment and Securing:

• The rotary axis should be precisely aligned perpendicular to the laser beam and parallel to the base plate to ensure stable engraving.
• Use clamping devices to securely fix the workpiece and avoid errors such as slipping or step losses, which improves engraving accuracy.

5. Conclusion

By correctly installing and configuring the rotary axis, you can achieve highly precise engravings on cylindrical objects and expand your creative possibilities. Optimized parameter adjustments and proven usage techniques enhance engraving results and lead to even more impressive designs. Using the rotary axis makes your laser engraving machine more versatile and opens new avenues for personalized designs. Try it out and take your ideas to the next level!
