How to Make Arduino Based Mini CNC Plotter Using DVD Drive

this a mini CNC 2D plotter made from old DVD drive and L293D motor shield very cheap but intresting

let see how to make

It is very easy to make all the step by step procedure is mention in this instructable

Step 1: Video of CNC Machine Working

Lets see the video this video also cover step by step procedure how to assemble the machine

Step 2: Material Need for This Project

1) 2 X SCRAP DVD DRIVE

2) 1 X ARDUINO UNO R3 / ARDUINO MEGA

3) 1 X L293D MOTOR SHIELD

4) 1 X SERVO MOTOR (TOWER PRO 9G)

5) JUMPER WIRES

6) SOME HARDWARE NUT BOTS ETC

7) DOUBLE SIDE 3M TAPE

Librairy For Adafruit Shield Driver Motors extract the file and past them to arduino/libraries

Step 3: Assembling the Machine

Open the scrap DVD Drive and remove internal moving tray..

This tray having stepper mechanism on it this will act as our X-axis & Y-axis.

Go through the attached pictures for understanding how to assemble your machine.

make hole on empty DVD drive case mount our X-axis and Y-axis on respective DVD case with the help of nut bolts.

Now place them perpendicular

Step 4: Wiring Details

watch the picture carefully and wire components accordingly

Step 5: CNC Code for Arduino

upload the code to arduino using arduino IDE

CNC_code.ino
Download

Step 6: G Code

To make gcode files that are compatible with this cnc machine you have to use the Inkscape.

Inkscape is professional quality vector graphics software which runs on Windows, Mac OS X and Linux.

It is used by design professionals and hobbyists worldwide,

for creating a wide variety of graphics such as illustrations, icons, logos, diagrams, maps and web graphics. Inkscape uses the W3C open standard SVG (Scalable Vector Graphics) as its native format,

and is free and open-source software. Download and install Inkscape from https://inkscape.org/en/download/windows/ (Important: download 0.48.5 version)

Now you need to install an Add-on that enables the export images to gcode files. This add on can be found here with installation notes.
