Contributions summary:Dmitry primarily contributed to the "klipper" 3d-printer firmware project by adding support for input shaping, a technique to reduce vibrations and improve print quality. Their initial commit introduced the core functionality of input shaping, along with the necessary code changes in the `kin_shaper.c` file. Subsequently, they developed scripts to simulate the response of the input shaper and movement of the toolhead. Further contributions included fixing C module compilation issues, migrating the avrsim script to Python 3 and implementing a resonance testing feature with automatic calibration of the input shapers and more.
