The aim of this online help is to teach you how to use CNCSimulator Pro. We assume that you have some experience in CNC programming so we do not explain CNC in general. The simulator consists of an editor for writing and editing CNC code, a 2D and 3D graphics view for simulation of machines and the tool paths, and a virtual CNC controller. There is also a built-in CAD/CAM system called SimCam, a 3D Maker tool, a Gear tool, and more. We suggest you start by loading and testing the various machines with the provided CNC code samples. The program has built-in tools and workpieces that you can play around with until you feel ready to set up your own. Have fun!
