Worked on the pcdshub/mfx repository to address a reliability issue in fiber operations by correcting the shutter channel configuration for evo_shutter1, ensuring it used channel 8 instead of 7. Focused on targeted bug fixing and maintainability, the work involved Python-based configuration management and hardware control to prevent shutter misoperation in fiber workflows. Additionally, improved log readability by refining newline formatting, which aids in debugging and ongoing maintenance. No new features were introduced during this period, as efforts centered on enhancing system reliability and operational accuracy through precise code updates and practical problem-solving within the existing hardware control path.
