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。

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

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

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。

占美 1037u 迷你電腦安裝 Ubuntu Linux

占美 1037u 迷你電腦，2013 年的產品，蠻舊的。在露天拍賣買的，$1,579，免運費。拿到機器就直接插電測試，卻看不到指示燈。拆開機殼查看，發現有2個藍色指示燈，卻沒有對準開孔，不曉得這樣裝是要幹嘛。後來再檢查接線，兩個LED是並聯的，就更讓人納悶這是在幹嘛。

主機板的型號 GHM7X VER. A，可惜找不到板子的相關資訊，這就是玩大陸生產的東西不好的地方，台灣生產的也差不多，都不願意公開技術資訊。

CPU 和晶片組焊在板子的背面，使用機殼散熱。

買它的目的是想用它來裝 Klipper，控制 3D印表機。蠻奇怪的，插上 USB 隨身碟就抓不到鍵盤，也無法從隨身碟開機。後來把 Thinkpad 已經裝好 Ubuntu 的SSD拔過來裝上，就可以開機了。

上面原來有一個 24GB 的 msata SDD，原來是裝 Win7。Ubuntu 裝好後，大約佔用 10GB 的空間，就用 cpio 把它 clone 到這個 msata SDD 上，再把控制3D印表機不需要用的軟體砍一砍。

整個安裝複製的過程大致整理如下。

先確認 Ubuntu 的 partition 和 file type。主分割區是 ext4，開機分割區是 vfat32。

root@ajax-ThinkPad-X220:~# df -Th Filesystem Type   Size  Used Avail Use% Mounted on tmpfs      tmpfs  382M  1.7M  381M   1% /run /dev/sdb3  ext4   219G  9.2G  199G   5% / tmpfs      tmpfs  1.9G 0  1.9G   0% /dev/shm tmpfs      tmpfs  5.0M  4.0K  5.0M   1% /run/lock /dev/sdb2  vfat   512M  5.3M  507M   2% /boot/efi tmpfs      tmpfs  382M  112K  382M   1% /run/user/1000

msata ssd 原來的分割區。

Disk: /dev/sda            Size: 22.37 GiB, 24015495168 bytes, 46905264 sectors                     Label: dos, identifier: 0x89b50dd4 Device   Boot  Start   End   Sectors  Size  Id Type >>  /dev/sda1   *     2048 206847 204800   100M   7 HPFS/NTFS/exFAT /dev/sda2        206848  46901247  46694400 22.3G  7 HPFS/NTFS/exFAT Free space      46901248  46905263  4016 2M

Ubuntu 的分割區，使用 gpt 分割表。

Disk: /dev/sdb          Size: 223.57 GiB, 240057409536 bytes, 468862128 sectors        Label: gpt, identifier: 7F3A45A7-012A-4334-A4D6-56D8572C44BE Device         Start     End Sectors Size Type >>  /dev/sdb1       2048    4095    2048   1M BIOS boot      /dev/sdb2       4096 1054719 1050624 513M EFI System /dev/sdb3    1054720   468860927   467806208   223.1G Linux filesystem

格式化磁區，然後再用 cpio 複製磁區。

root@ajax-ThinkPad-X220:/# mkfs.vfat -F 32 /dev/sda2 root@ajax-ThinkPad-X220:/# mkfs.ext4 /dev/sda3 root@ajax-ThinkPad-X220:/# mount /dev/sda2 /mnt root@ajax-ThinkPad-X220:/# cd /boot/efi root@ajax-ThinkPad-X220:/# find ./ -xdev -print0 | cpio -pa0V /mnt root@ajax-ThinkPad-X220:/# umount /mnt root@ajax-ThinkPad-X220:/# mount /dev/sda3 /mnt root@ajax-ThinkPad-X220:/# cd / root@ajax-ThinkPad-X220:/# find ./ -xdev -print0 | cpio -pa0V /mnt

參考下面的連結，使用 chroot 設定開機磁區，How to Repair or Re-install GRUB using the chroot command/

步驟如下
