[Marlin 2.1.2](https://marlinfw.org/meta/download/), unveiled on December 18, 2022,
brings a host of new features to the world of 3D printing firmware, with a spotlight
on the introduction of input shaping.

## _Marlin 2.1.2: What is Input Shaping and Its Impact on Printing Speed?_

Input shaping, also referred to as resonance compensation, stands as a sophisticated
computational process. It aims to counteract the inherent vibrations of a 3D printer,
effectively eliminating visual artifacts such as resonance on the printed surface.
The significance of input shaping becomes apparent when users strive to increase
printing speed, effectively addressing common printing defects like ringing. The
synergy of input shaping with calculations such as linear feed offers users the 
ability to achieve significantly higher printing speeds than previously attainable.

## **Experimental Nature and Manual Calculation**

While the potential of input shaping is promising, it’s essential to note that Marlin’s
implementation, designated under the M593 command, is still in the experimental 
stage. Users are encouraged to actively participate in the development process by
reporting any issues they encounter on the Marlin Firmware GitHub. Notably, the 
current version of input shaping on Marlin requires manual computation. Users must
measure a resonance tower, as detailed in Klipper’s comprehensive guide. As of now,
Marlin does not support accelerometer integration for automatic vibration handling.
