Developed slit control enhancements for the pcdshub/mfx repository, focusing on granular per-slit control and improved validation workflows. Leveraging Python and software development skills, introduced features that allow individual or common aperture configuration for mfxslits, with per-move result reporting to increase operational transparency. Added a validation print capability to display final slit positions, supporting both debugging and validation processes. Updated supporting scripts, including macros.py, to integrate these new capabilities and streamline user interaction. The work emphasized debugging and scripting best practices, resulting in more reliable and observable slit control operations, while maintaining a clear and maintainable codebase throughout the development cycle.
