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.

这是一个 Marlin 自动调速插件。它使用 arduino nano 和 MPU9250(陀螺仪) 制作，安装在打印机顶部。

1. 没有震动时，打印速度会慢慢变快；
2. 当发生震动时，打印速度会自动降低；

通过这个简单的原理，来实现动态调节速度。增强打印效果。

原始灵感来自 https://news.engin.umich.edu/2017/10/3d-printing-gets-a-turbo-boost-from-u-m-technology/ 。 但这里的实现过于复杂，并且需要大量改动 Marlin 的代码。

我选择了一种更加简单，成本更低，更少改动原版 Marlin 的方式来实现。如果你使用这种陀螺仪感应震动来实现自动调速，请保留原始出处，谢谢。
