Free Gear Generator for LightBurn | Optimized DXF & SVG for Laser Cutters

Engineered specifically for LightBurn laser cutting and engraving software. GearDXF exports continuous closed-path vectors that LightBurn loads instantly as single closed cut shapes with zero duplicate lines, open loops, or stuttering node clusters.

Key Features

• 100% closed-path vectors recognized instantly by LightBurn without auto-joining
• Zero overlapping duplicate line segments that cause double-burn marks
• Backlash control to offset laser beam kerf width (0.1mm - 0.25mm)
• Export multi-gear sets nested cleanly on your laser cutter workbed
• Optimized for CO2, diode, and fiber laser cutters
• Free forever with zero registration or watermarks

Frequently Asked Questions

Why do generic gear DXFs stutter or cut improperly in LightBurn?

Many CAD tools export gear curves as hundreds of disjointed line segments. LightBurn must process every endpoint, slowing down the laser head. GearDXF exports smooth, continuous polylines for fast, flawless cutting.

Should I import DXF or SVG into LightBurn?

Both work flawlessly. SVGs preserve clean visual colors and layers, while DXFs maintain strict absolute millimeter dimensions with CAD-level precision.

How do I set up kerf offset in LightBurn with GearDXF?

You can either apply your kerf offset directly in LightBurn (under Cut Settings > Kerf Offset) or adjust the backlash slider in GearDXF before exporting.
