The main aim is to fabricate a Mini CNC plotter Machine to draw an object with using G codes. Stepper drivers are used to give command to the system. Stepper motor is convert digital pulse into lead screw rotations. We have used stepper motors with lead screw in Cartesian coordinate X,Y directions. The aim of over is to make a mini CNC plotter machine which is capable to draw difficult design in paper or surface of metal, To cut it with a great accuracy.

Pen can be changed by tools of drilling, laser cutting tool, milling it can be worked, if it is made in large size. G codes are giving the Direction to move the pen in X, Y directions. In CNC Plotter Machine only G codes are used. G codes are pre-define Function Associated with the movement on machine axes. CNC is computer numerical control machine. Mini CNC plotter machine is described as it is based on Arduino controller and CNC shield. By controlling a CNC machine through a PC it is possible for the user to design a product on-screen, convert it to CNC-readable code and then send that data to CNC machine for it to produce a physical copy of the item designed. The Z axis is being parallel with the spindle. Three-axis machine can do movement starting with three primary axis which are X, Y and Z axis. The two-axis machine can move on vertical and horizontal only which are X and Y axis. The common CNC machines are two-axis and three-axis CNC machine. Since the motors can turn very small amounts the machine is able to move in highly precise movements over and over again. The signals from the computer are then used to control motors. A CNC machine takes codes from a computer and converts the code using software into electrical signals.

It also is a specialized and versatile form of a Soft Automation and its applications cover many kinds, although it was initially developed to control the motion and operation of machine tools. CNC stands for Computer Numerical Control and typically refers to a machine whose operation is controlled by a computer.
