Automatic Speed for Marlin 3D Print

This is a Marlin automatic speed control plug-in. It uses arduino nano and MPU9250 (gyroscope) production, installed in the top of the printer.

1. Without vibration, the printing speed will be faster and faster;
2. When the vibration occurs, the print speed will be automatically reduced;

Through this simple principle, to achieve dynamic adjustment speed. Enhance the printing effect.

Originally inspired by https://news.engin.umich.edu/2017/10/3d-printing-gets-a-turbo-boost-from-u-m-technology/. But the implementation here is too complicated and requires a lot of changes to Marlin's code.

I chose a simpler, lower cost, less change the original Marlin way to achieve. If you use this gyroscope to sense vibration to achieve automatic speed control, please retain the original source, thank you.
