OrangePi Zero 3安装Klipper

本文最后更新于：2025年6月4日 下午

刷入官方Debian系统

优选Linux6.1内核版本的镜像，支持CAN网络，Linux5.4内核版本不支持CAN网络！

可以使用以下命令检查系统内核是否支持CAN网络：[1]

1
sudo modprobe can && echo "您的内核支持CAN" || echo "您的内核不支持CAN"

使用balenaEtcher软件刷入Debian官方镜像。

连接WIFI

  1. 图形模式

    打开nmtui界面：

    1
    sudo nmtui

    使用键盘⌨方向键选择Activate a connection，然后选择需要连接的WIFI名，输入WIFI密码后等待连接成功即可。

  2. 命令行模式

    扫描WIFI：

    1
    nmcli dev wifi

    连接WIFI：

    1
    sudo nmcli dev wifi connect wifi_name password wifi_passwd

    wifi_name: WIFI名称
    wifi_passwd: WIFI密码

    连接成功后，查看WIFI的IP地址：

    1
    ip addr show wlan0

安装所需软件

1
sudo apt install git python3 python3-pip -y

更换软件源

  1. apt源：
    橘子🍊官方已将apt源换成华为的镜像源，所以无需再操作。

  2. pip3源：

    本文章示例更换pip3为阿里云的源：

    1
    pip3 config set global.index-url https://mirrors.aliyun.com/pypi/simple
    1
    pip3 config set install.trusted-host mirrors.aliyun.com

    查看pip源的配置信息：

    1
    pip3 config list

    以下列出国内pip3源地址，可按需替换：
    阿里云：http://mirrors.aliyun.com/pypi/simple/
    清华大学：https://pypi.tuna.tsinghua.edu.cn/simple/
    中国科技大学：https://pypi.mirrors.ustc.edu.cn/simple/

设置网络代理

由于国内网络环境复杂，为了防止后续操作出现异常情况，可以进行网络代理，避免下载失败导致安装不成功或者环境配置异常。

在与OrangePi Zero 3同一局域网下，使用一台Windows电脑运行Clash Verge，并配置好代理，在设置中开启局域网连接功能，并查看当前电脑的IP和端口（需替换命令中的ip和port部分）：

  1. 临时网络代理

    临时代理只在本次会话中有效，如果系统重启就会失效。

    1
    export http_proxy=http://ip:port
    1
    export https_proxy=http://ip:port

  2. 永久网络代理

    为所有用户启用网络代理，并且不会因系统重启而失效。

    1
    sudo nano /etc/environment
    1
    2
    3
    export http_proxy="ip:port"
    export https_proxy="ip:port"
    export no_proxy="localhost,127.0.0.1,::1"
    1
    sudo reboot

使用KIAUH脚本安装Klipper

克隆KIAUH官方仓库：

1
git clone https://github.com/dw-0/kiauh.git

运行KIAUH脚本：

1
./kiauh/kiauh.sh

安装组件：Klipper、Moonraker、Web

运行脚本可能会出现以下界面，询问是否体验KIAUH v6测试版，测试版包含了一些新功能；我们使用稳定版操作，输入2回车。

KIAUH脚本主界面：

安装核心必备组件：Klipper、Moonraker，而网页界面：Mainsail / Fluidd，任选其一安装即可：

给OrangePi Zero 3刷入Klipper固件

依次执行以下命令：[2]

1
cd ~/klipper/
1
sudo cp ./scripts/klipper-mcu.service /etc/systemd/system/
1
sudo systemctl enable klipper-mcu.service
1
make menuconfig

按照图片中进行配置

1
sudo service klipper stop
1
make flash
1
sudo service klipper start

执行完以上操作后，重启上位机，登录SSH，查看是否有本地串口：

1
ls /tmp

此时可能会没有本地串口：klipper_host_mcu，如下图：

查看是否有本地串口

接下来查看klipper-mcu的运行状态：

1
systemctl status klipper-mcu.service

查看Klipper MCU状态，显示有报错！

我遇到的情况是使用以下命令进行修复的，仅供参考：[3] [4]

1
2
sudo sysctl -w kernel.sched_rt_runtime_us=-1
echo "kernel.sched_rt_runtime_us = -1" | sudo tee /etc/sysctl.d/10-disable-rt-group-limit.conf

修改内核后执行重启

执行上述命令后，再次执行ls /tmp命令可以看到已经有本地串口：

已成功启动Linux MCU本地串口，可以到网页端进行配置引脚进行使用

橘子官方提供了2个不同Linux内核（5.4 / 6.1）的系统，分配的gpio管线不一致，可以按照如下操作查看当前系统的管线配置：

先安装工具：

1
sudo apt-get install gpiod

检查GPIO管线分配情况：

1
sudo gpiodetect

以下附上5.4与6.1内核的管线分配截图，对比会发现他们的gpiochip号互为相反：

5.4内核的GPIO管线分配情况

6.1内核的GPIO管线分配情况

检查引脚号以及可用性：

1
sudo gpioinfo

以下分别附上香橙派Zero3的13 PIN & 26 PIN 接口的引脚功能分配图（也可以使用gpio readall命令查询）：

13 PIN引脚功能分配图

26 PIN引脚功能分配图

所有PIN引脚功能分配图

编写OrangePi配置文件

此配置文件可搭配我给OrangePi Zero3画的Hub板进行使用，其中pin脚的gpiochip号需要配置为上述内核中实际查询的，否则会报错：MCU 'host' error during config: Unable to open out GPIO chip line，仅供参考：

如果需要使用硬件接口：UART接口、IIC接口、SPI接口，需要在sudo orangepi-config中开启相应接口并重启系统后才可实现对应功能，点击对应接口查看官方文档操作即可。

# The rpi microcontroller is used as secondary.
# Typically, both the X and Y axes
