Simulating 2D CNC cutting path, lead-in/Lead-out and cutting sequence from the NC code file. Showing NC block progress sequence on the NC code list window. Supporting NC block progress speed adjustment. Zoom-in, zoom-out and zoom-extend in the display windows are available for detail checking. It is easy to check whole entire cutting path fastly when maximum speed is set. Both cutting path and NC block progress sequence are shown same time. Able to pause at any moment during simulation and also able to continue simulation again from paused location. Requires Windows 2000 or above, RAM512 MB,10MB HDD or above.
