使用電腦執行 Klipper 控制 MKS Gen_L V2.1

想使用 docker 來測試 klipper，參考 https://github.com/mkuf/prind。

那個 type-B 的 USB 接頭實在很煩，線又很短，有空來換成 type-c 的接頭吧。連上後，使用 dmesg 顯示訊息如下。

------------------------------------

[   55.491549] usb 2-1.1: new full-speed USB device number 4 using ehci-pci
[   55.601246] usb 2-1.1: New USB device found, idVendor=1a86, idProduct=7523, bcdDevice=81.34

-----------------------------------

使用 Gentoo，必須設定和編譯 Kernel，新增 module「USB Winchiphead CH341 Single Port Serial Driver (USB_SERIAL_CH341)」。

從 MKS 的文件找到的 PIN 腳圖，把用到的 PIN 腳改成 Klipper 使用的標號。
