Introduction: How to Make Mini CNC 2D Plotter Using Scrap DVD Drive, L293d Motor Shield & Arduino
this a mini CNC 2D plotter made from old DVD drive and L293D motor shield very cheap but intresting
let see how to make in
Step 1: Video
Step 2: Material Need for This Project
1) 2 X SCRAP DVD DRIVE
2) 1 X ARDUINO
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
You can buy this material from below links of Amazon
Librairy For Adafruit Shield Driver Motors
extract the file and past them to
Step 3: Assembling the Machine
Open the scrap DVD Drive and rremove 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
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
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
(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
Step 7: Processing IDE Program (GCTRL)
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
