FlatCAM
是免费和开源的 PCB CAM，采用 Python + PyQt编写，在大多数平台上稳定运行。FlatCAM 是一种为在数控雕刻机上制造 pcb 的数控工作的程序。它将您的 PCB 工程项目生成的 Gerber 文件，转换成数控雕刻机通用的 G-Code 代码。

-- GRBL controller application with G-Code visualizer written in Qt
Candle的文件解析GcodeParser.cpp来源自Will Winder编写的“ Universal GcodeSender”开源项目。此文件最初是从“ GcodeViewParse.java”类移植的。而Universal-G-Code-Sender又是基于grbl的java版本。
grbl：使用优化的C语言编写的开源，嵌入式，高性能g代码解析器和CNC铣削控制器，将在直接的Arduino上运行。

https://github.com/Ultimaker/CuraEngine 开源的仿真软件HOPSAN
Hopsan是一个免费的开源多域系统仿真工具，由林平大学流体与机电系统系开发。
https://github.com/Hopsan/hopsan SoftPLC, IEC 61131-3
按照工业控制领域常用的IEC61131-3标准来看，工业控制领域程序语言被分为了两大类五种语言，两大类是指图形化编程和代码编程，图形化编程中有Ladder（梯形图），FBD（Function Block Diagram，功能块图）和SFC（Sequential Function Chart，序列功能表），而代码编程有IL（Instruction List，指令集）和ST（Structured Text，结构化文本）。
几个著名的开源项目：
PLCEdit：完全按照IEC61131标准开发，所有五种语言均支持，使用Python开发，故可以做到跨平台。
Beremiz：一套完整的开源PLC解决方案，不过放在这里主要是因为它不但使用了上面说的PLCEdit，同时还对其进行了增强，使得其增加了重要的在线调试功能。推荐！！！
SoapBox Snap：使用C#+WPF开发的，仅支持梯形图一种语言，不过却已经支持了在线调试功能，含模拟器。
