- A plugin (sometimes referred to as a driver) allows people to add custom functionality to Mach3/Mach4. Plugins are written as .dll files in programming language in Mach3. Plugins for Mach4 include both a .sig and .m4pw file. They are primarily used to enable Mach3/Mach4 to work with hardware devices (e.g. external motion controllers), but can also be used to add functionality (e.g. Mach3’s Flash plugin) or extend existing functionality (e.g. Mach3’s Jcode plugin).
- Visual C++ 2003 is required to create Mach3 plugins.
