The virtual CNC controller lets you simulate the behavior of a simplified machine CNC controller. You can see feed rates and RPMs in percent of maximum values as well as indicators for coolant water, spindle, etc. You can also control the running mode of the virtual machine like for example changing between continuous to single-step mode. You open the virtual CNC controller by clicking on the tab Controller to the right. Please note that you cannot switch between the Editor and the virtual CNC controller while the simulation is running.
