The widely used 3D printer firmware now supports input shaping thanks to the Marlin 2.1.2 launch this past Sunday. The release’s accompanying text centers on the addition, perched at the top of a list of twelve new features.
Print imperfections like ringing are frequently the first barrier to increasing printing speed. Input shaping, also known as resonance compensation, is a calculation that aims to remove visual artifacts like ringing from a printed surface and the vibrations of a 3D printer. Input shaping allows users to print much more quickly than they could otherwise, especially when combined with other calculations like linear advance.
One of the main reasons for choosing the Klipper firmware over the more widely used Marlin is the availability of input shaping; however, the additional hardware needed to install Klipper, typically a single-board computer, may deter some users since input shaping is also available on Marlin.
The release emphasizes that the feature is still considered experimental and that there is currently limited information on Marlin’s input shaping, which is now associated with the M593 command. As a result, report any issues on the Marlin Firmware GitHub. Sadly, it also seems that Marlin’s input shaping is only possible through manual calculation. You won’t be able to use this feature by simply plugging in an accelerometer to handle vibrations; instead, you’ll need to measure a ringing tower. Of course, Marlin won’t respond to the console commands that its walkthrough gives you. Klipper, fortunately, has a thorough explanation of the procedure.
