How to Calculate Split Size for Rotary Laser Engraving

To split a design for rotary laser engraving on cylindrical objects, follow these steps:

1. Measure Dimensions: Determine the object’s diameter and calculate the circumference.

2. Set Design Length: Match the design length to the object’s circumference for a full-wrap.

3. Divide into Sections: Split the design into parts that fit within the machine’s engraving area.

4. Add Overlap: Include a small overlap (1–2 mm) for seamless alignment.

5. Adjust Settings: Input the diameter into your rotary attachment for accurate rotation.

6. Engrave in Sections: Align each section, engrave, and rotate the object until complete.

Software like LightBurn can automate splitting designs based on object size and machine limits.
