前言

这里主要讲上位机klipper的配置，硬件使用大鱼的设计，主板mks genl2.1，klipper安装于上位机。
mks的说明书已经详细说明了klipper的搭建配置过程：MKS GEN_L V2.1 Klipper固件使用说明书
MKS GEN_L V2.1

对mks配置文件的修改

lcd

我没有使用lcd屏，但是mks提供的配置文件printer.cfg对lcd进行了配置，需要删除，这一点说明书没有提及，lcd配置include了其他文件，文件在mks的github仓库可以找到。

pin

我为打印机加装了LED灯带，但是不希望灯一直打开，需要开关功能。由于我没有lcd屏幕，所以可以使用lcd的引脚控制L298N驱动LED灯带。
klipper使用芯片的引脚名称，与marlin不同，mks的github仓库虽然给出来对应关系但是并不完整，具体引脚编号可以查看主板原理图上mega2560芯片的内容。
