Worked on the bambulab/BambuStudio repository to enhance the printing configuration workflow by developing a boundary-aware skirt loop auto-arrangement feature. This involved refining the underlying algorithm in C++ to accurately calculate skirt loop widths based on parameters such as initial layer line width and nozzle diameter, ensuring all loops fit within the buildable area. The approach included adding comprehensive unit tests to validate the new boundary logic and address draft shield scenarios, supporting regression safety. Through focused algorithm design and test-driven development, the work improved print reliability by reducing build-area violations and enabling more predictable, user-friendly skirt configuration experiences.
