Ivan spends time explaining that CNC Machine Controllers take the machining instructions that were made from your G-Code and converts the G-Code into motion that your Computer Numerical Machine will understand. Your CNC Controller is very important in the Computer Numerical Control Process because it’s the last link in order to get your design made on your Computer Numerical Control machines. The controller interprets the signal pulses from your Control Computer and instructs the machine to move.
