PROFILE
Shirley Du
Shirley Du enhanced the Ultimaker/Cura repository by developing granular bead-mode motion control for Makerbot Writer Method printers, integrating acceleration and jerk parameters into meta.json with both global and extruder-specific values. Using Python and configuration management techniques, Shirley implemented conditional feature gating to enable input shaping and corner rounding exclusively for high-speed print modes, improving print quality and workflow safety. She also addressed a configuration bug by restricting per-mesh and per-extruder acceleration and jerk settings, including a robust rollback to maintain system stability. Her work demonstrated depth in backend development, firmware integration, and disciplined version control within a complex 3D printing environment.

Jan 1, 2025January 2025 monthly summary for Ultimaker Cura focusing on Method printer motion control and high-speed print enhancements. Key features delivered include granular bead-mode motion control by integrating acceleration and jerk into meta.json with global and extruder-specific bead-mode values (applied only when non-zero). Implemented conditional enabling of advanced features (input shaping and corner rounding) for high-speed print modes. Major bug fixed: disallow per-mesh/per-extruder acceleration/jerk settings on Method printers, with a revert to undo a missing-file scenario to preserve stability. Impact: improved bead-mode precision and print quality on Makerbot Writer Method printers, safer high-speed printing workflows, and reduced configuration errors. Skills demonstrated include JSON-driven configuration changes, feature-flag style gating, version-control discipline, and robust rollback procedures.
