These complex sub-layer settings can be saved to the LightBurn library for future, one-click application to new projects. 3. Critical Fixes and Known Issues

The camera calibration process was refined to utilize a center crosshatch pattern, intended to improve precision in aligning the camera view with the laser bed. 2. Workflow Enhancements: The Sub-Layer System

If the laser hangs during long jobs, disabling USB selective suspend in Windows power settings and toggling "Enable DTR Signal" in Device Settings has been the recommended fix.

While bringing new features, 1.3.01 addressed specific bugs but introduced minor operational quirks that some users reported:

The headline feature is the introduction of a tab system within the cut settings, allowing users to add multiple sub-layers to a single main layer. This is crucial for complex projects requiring different actions (e.g., cut, 45-degree fill, -45-degree fill) on the same vector without creating multiple color-coded layers.

The "Line and Fill" mode options were re-organized in this version, with discussions noting that documentation was updated to reflect this change.

1.3.01 expanded compatibility with ComMarker B4 and other "Dynamic" FPGA-based boards. It also included preliminary support for SPI galvo sources, strengthening LightBurn’s position in the fiber laser market.
