Flat surfaces are simple—but once you start engraving cylindrical items like suppressors, barrels, flashlights, or cups, you enter the world of rotary engraving. Done right, it unlocks a whole new level of precision and professionalism.

What Is Rotary Engraving?

Rotary engraving uses a rotary axis attachment to rotate the object while the laser engraves, ensuring the mark stays consistent around curves.

Perfect for:

• Suppressors
• Barrels
• Mag tubes
• Tumblers and drinkware
• Pipes or custom cylindrical tools

What You Need

1. Rotary Attachment
There are two main types:

• Chuck-style (like a lathe): best for precise or smaller parts
• Roller-style: better for larger items like tumblers or flashlights

2. Software Support
Make sure your laser software supports rotary mode. In EZCAD, enable “RotaryMark” in parameters. In LightBurn, toggle “Rotary Setup” under tools.

3. Correct Setup

• Align your rotary parallel to the laser bed
• Center your object’s engraving area
• Focus carefully on the highest point of the curve

Key Settings to Adjust

Pro Tips

Use a test cylinder to dial in your settings before marking real items
Always tighten the object securely to avoid slippage
When marking on barrels, ensure serials are on the visible side

Common Mistakes

Forgetting to enable rotary mode = warped text
Using the wrong axis = misalignment
Incorrect diameter = distorted images or fonts

Wrap-Up

Rotary engraving may seem intimidating at first, but once it’s dialed in, it opens the door to professional-level markings on parts most shops avoid. Take your time, double-check your setup, and test often.
