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.

If your marks are coming out blurry, shallow, or inconsistent, chances are your focal distance is off. Dialing in your laser’s focus is one of the most critical—but often overlooked—steps for achieving sharp, clean engravings.

What Is Focal Distance?

The focal distance is the sweet spot between your laser’s lens and the surface being engraved. It’s the point where the beam is most concentrated—meaning maximum power and precision.

Too high or too low = scattered beam = poor results.

How to Find the Right Focus

1. Manual Focus Rods
Many fiber lasers come with a pre-measured focus rod. Line it up between the lens and the surface = perfect height.

2. Autofocus Systems
Some premium setups auto-adjust based on surface detection—but always double-check manually.

3. Ramping Method (For Dialing in Manually)

• Create a sloped surface (e.g., angled block)
• Run a single line mark across the slope
• The sharpest/thinnest point = your focal distance

Standard Focal Lengths (Based on Lens Size)

Tip: These can vary slightly based on brand and fiber source.

What Happens If You’re Out of Focus?

Blurry, wide lines
Inconsistent depth
Burned edges or hot spots
Wasted time and materials

Pro Tip:

Mark your laser housing with focal length indicators for different lenses—it’ll speed up your workflow and cut down on test passes.

Final Thoughts

Mastering focus = mastering detail. It’s the bridge between power and precision—and once you’ve got it locked in, your engraving quality will jump up fast.

One of the most rewarding parts of laser engraving is turning a unique design into a permanent mark. Whether you’re branding gear, personalizing a build, or offering client services, clean vector files are the foundation of professional-quality engraving.

Why Vector Files Matter

Laser machines don’t “see” images like we do—they follow paths. That’s why vector formats like .SVG, .AI, and .DXF are essential.

Raster image (e.g., .JPG/.PNG) = pixel-based
Vector image (e.g., .SVG/.AI) = path-based = perfect for laser travel

Best Software for Vector Design

• Adobe Illustrator – Industry standard for precision
• Inkscape – Free and powerful open-source option
• LightBurn – Designed for lasers; lets you design and send files in one place
• CorelDRAW – Often used in commercial shops

Tips for Creating Laser-Ready Files

Use bold, clean lines
Avoid thin or overly detailed designs—they may not translate well at small sizes.

Convert all text to paths/outlines
This ensures fonts don’t change or get corrupted during import.

Keep fill settings in mind
Filled shapes vs outlines behave differently—test before engraving.

Size your artboard to match your laser bed or work area.

Converting Raster to Vector

Got a JPEG logo? No problem.

1. Open it in Illustrator or Inkscape
2. Use “Image Trace” or “Path > Trace Bitmap”
3. Adjust threshold until edges look clean
4. Expand or convert to paths
5. Save as .SVG or .AI

Pro Tip:

Before running your job, preview it in line mode to see how the laser will trace each path. This helps avoid surprises like double lines or broken paths.

Wrap-Up

Clean vectors = clean engraves. Whether you’re engraving serialized parts or branding a project, putting in the extra effort on your file prep pays off big time.
