Home Contact The CNC Controller The CNC controller is the brain of a CNC system. Controllers Components This section covers the components that make up a CNC controller system and how they work together to control the machine.
This system may include the protection circuitry, stepper or servo motor drivers, power source, limit switch interfaces, power controls, and other peripherals. A controller completes the all important link between a computer system and the mechanical components of a CNC machine. Owners, operators, designers, and builders of CNC devices should understand the tasks performed by these components and how they affect machine performance. The word controller is a generic term that may refer to one of several devices, but usually refers to the complete machine control system.
