CNC( computer Numerical Control) is the control and automation of machine using certain alphanumeric codes. Fabrication of 3-axis CNC milling machines based on A4988 driverboard which combined with spindle drill is being discussed through this paper. Cutting, Engraving and Marking on wood, acrylic and PCB objects can be done using this CNC machine. Command data code are generated and send to microcontroller using a Universal Gcode Sender.
