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

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

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

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

watch the picture carefully and wire components accordingly

upload the code to arduino using arduino IDE

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.

please follow the video on you tube how to create G-code file

some ready made G-code files

Upload the gctrl file to processing IDE

and click on PLAY button in processing window.

first press ‘p’ to select you com port if you want

you can set jog speed by pressing 1,2, or 3 button

from keyboard press ‘g’ to load G-code file your machine is ready to plot

as soon as you hit enter by selecting g code file now you have done

your plotter is ready

thanks for your attention
