How to Make Mini CNC Machine at Home

Hi guys , As per the title this is a simple project using Arduino to make Homework writing machine at your home.This machine can draw any design and write any type of fonts.and home made watch full video

1) OLD Dvd Writer

2) Arduino Nano

3) A4988 driver Stepper Motor Driver Module

4) Servo moror

5)12V 1A DC Power Adapter

6)PCB BOARD

First of all you need 2 DVD writers of your CPU.You can use non workable DVD writer for this project.

Take 2 DVD writers and open 5 screw on bottom of this DVD writer.Then open bottom case of DVD writer and disconnect all circuit. Then open Top case of DVD writer.

After this you see rectangle part of DVD writer with stepper motor on back side.Open 2 screw on this Rectangle and remove this rectangle outside.
Repeat this process for 2nd DVD writer. After this you have two PCs of Rectangle Part (AS per 2nd Pic.)

Take female header pin (4 pin) as a picture.

Connect two stepper motor with this 4 pin female header as show in picture(In the same line).

Connect With X-Y - Axes Gantry.

Ready your all circuit.1) 2 PCs A4988 Stepper Motor Driver with heat sink

2)Expansion Board A4988 Driver

3)Arduino Nano First of all take hit sink and stick on A4988 stepper motor Driver. 2 PCs A4988 Stepper Motor Driver connect on Then this combination connect on Arduino nano (As per circuit Diagram).
