项目开源网站 LinuxCNChttps://www.linuxcnc.org/当前release版本2.8.4

Downloads (linuxcnc.org)https://www.linuxcnc.org/downloads/可以直接下载安装好linuxcnc的实时debian系统，直接刻盘安装就可以了

 安装IgH主站，网上有很多教程可供参考

git clone https://gitlab.com/etherlab.org/ethercat.git

安装linuxcnc-ethercat

git clone https://github.com/sittner/linuxcnc-ethercat

1. cd linuxcnc-ethercat

2. sudo make configure

3. sudo make

4. sudo install

安装cia402，控制ethercat伺服需要用到

git clone https://github.com/dbraun1981/hal-cia402

cd hal-cia402

sudo compile --install cia402.comp
