PROFILE
Christian Kunis
Worked on Ultimaker/Cura to enhance 3D printing reliability and user experience by refining printer profile configurations, tuning motion parameters, and expanding test coverage. Focused on Python and C++ to implement parametric controls for cooling and acceleration, streamline configuration management, and address bugs affecting print quality and consistency. Delivered features such as improved infill width, elephant’s foot compensation, and Voron-specific profile enhancements, while maintaining safe defaults for new users. Addressed critical issues like adhesion type misrepresentation and redundant overrides, ensuring data integrity and maintainability. Emphasized code refactoring, software testing, and version control to support ongoing community-driven improvements and stable releases.
