What is a CNC? The abbreviation CNC stands for computer numerical control, and refers specifically to a computer “controller” that reads G-code instructions and drives a machine tool, a powered mechanical device typically used to fabricate components by the selective removal of material. In simple words, a CNC is a machine which is controlled by […]
Design, development and construction of an electronic controller for a CNC machine. The controller controls up to 3 stepper motors (up to 3 axes), has home and limit switches, and is optically isolated from the computer.
Stepper motors (also called step motors) are electronic motors that offer precise rotation control . Stepper motors are very precise (an average stepper motor can turn in about 0.9 to 1.8 degrees in each direction) and in a relatively high rotational speed. Stepper motors can be found in various types of hardware components: printers (the […]
