Lightburn 1.7.04 [extra Quality] May 2026

LightBurn 1.7.04 is a maintenance and patch release launched on December 16, 2024, designed primarily to improve stability and address specific bugs following the major 1.7 update. Key Updates and Fixes

1. Enhanced Galvo Fiber Laser Calibration

Fiber laser users have historically struggled with marking large areas due to "field distortion" (barrel or pincushion distortion). Version 1.7.04 introduces a refined 3-point and 5-point calibration routine. The algorithm now better compensates for lens aberrations, resulting in truer geometry when marking over 200mm x 200mm fields.

Get Ready to Upgrade!

• True Camera Calibration: Active warping for camera alignment without manual grid distortion.
• Batch Processing: Running multiple *.lbm files sequentially without human intervention.
• Galvo 3D Etching: True gray-scale height mapping for fiber lasers.

Shaded Selection Boxes: Selection boxes are now color-coded (red or green) to indicate the type of selection being made.

: LightBurn now supports Galvo lasers using BSL boards, making machines previously restricted to SeaCAD compatible. Enhanced Barcode Tool LightBurn 1.7.04

Changed:

Shifted the build server to macOS 13; while it still supports macOS 10.13+, it now depends on components from the OS 13 environment. LightBurn Software Bug Fixes & Technical Adjustments Shape & Path Handling LightBurn 1
