This patch resolves several technical issues that were affecting specific workflows: macOS Stability: LightBurn 1.7.04

No critical show-stoppers exist, which is why is being hailed as the new "baseline" stable version.

Rotary users (jigs for tumblers and bottles) reported inconsistent step sizes in 1.7.03. re-writes the rotary step calculations, specifically for continuous rotation jobs. The result is seamless 360-degree wraps without the "seam line" or "compression" errors that plagued earlier builds. Version 1

Previous versions optimized paths based purely on proximity. includes a refined algorithm that also considers material kerf and direction changes. For complex vector cuts (like puzzle pieces or gears), users report a 12-18% reduction in total job time because the laser head moves more intelligently between cut segments.

Unlike auto-updating software, LightBurn allows users to stick with a specific version that works for their workflow. However, is widely regarded as the "must-upgrade" patch for anyone still on 1.5 or early 1.6. However, the configuration file format changed between 1
