Computer numerical control (CNC) is the automation of machine tools by means of computers executing Gcode sequences of machine control command.

CNC are used in many applications Like.

Laser Engraver

CNC milling machine

This CNC Plotter is Made from old TVS dot Matrix printer(Tvs-e MSP 245 star Dot matrix Printer) and Old Scanner (used for Y axis). All the other Components are easily available.

Stepper motors are widely used in ROBOTICS and 3D printer and many types of stepper motors are available in market,

Types of Stepper motors are :
.
« Based on Wiring
1. Unipolar stepper motors
2.Bipolar stepper motors
3.Hybrid stepper motors

1.Unipolar motors are having more than 4 wires.(5 or 6 or even 8 wires )

2.Bipolar motors are having only 4 wires:(2phases).

3. Hybrid stepper motors are combinations of both unipolar and bipolar stepper motors..
