Input shaping allows faster 3D printing speed and acceleration, without a loss in quality. Available in most other firmwares, input shaping is now available in Marlin. In this video guide, we cover the setup and calibration process step by step on an Ender 3.

I’m really pleased with these results. Any time you can speed up 3D printing without losing quality, it’s a huge win. I look forward to playing with the new parameters when they are added in the future.
