What is CNC Macro Simulator II?

CNC Macro Simulator II is a lightweight CNC code editor and simulator designed to streamline the creation of macro programs for controls like Fanuc, Haas, Mazak (ISO), Centroid, and even Sinumerik, Heidenhain, or Okuma with built-in converters. It supports both 3-axis mills and lathes with C/Y axis and live tooling. The software operates offline on Windows, Linux, macOS, Android, and iOS, and is available for desktops, tablets, and mobile phones. While the simulator currently represents only 3 axes, the software can execute macro programs for up to 6 axes, offering debugging and conversion to plain G-code.
