In this project I will show you how to easily build your own low-cost Arduino Mini

CNC Plotter!

For X and Y axis we will use stepper motors and rails from two dvd/cd roms!

Printing area will be max 4x4cm.

Because it works with serial communication you can also use a Bluetooth

module (like HC-06) to print your stuff wirelessly through your computer

Bluetooth connection!

I have used the code from this

(http://www.makerblog.at/2015/02/projekt-mini-cnc-plotter-aus-alten-cddvd-laufwerken/)site, so I need to thank the

cnc-plotter-aus-alten-cddvd-laufwerken/)site, so I need to thank the

Makerblog.at for sharing this to us.

Part list for beginners:

Arduino uno

Breadboard

2x L293D ICs Motor driver

Mini Servo Motor

2x DVD/CD Drives

Part list for 'pro' :

ATmega328p (with Arduino Bootloader)*

2x L293D ICs

Mini Servo Motor

2x DVD/CD Drives

Prototyping PCB Circuit Board Stripboard

4x 2pins Screw Terminal Connector (or 2x 4 pins Screw Terminal

Connector)***

*You will need also an Arduino UNO board to program the ATmega328 micro

possessor

**USB to Serial adapter will allow the circuit to communicate with the computer

through the USB cable, just like Arduino uno does.

***Why to use screw terminal connectors? Because you don't want to solder and

desolder cables from stepper motors until you find the correct working

combination.

Tools (only for 'pro' part list):

Screwdriver

Soldering iron

Solder

Cutting tool (e.g. Dremel) (Optional for cutting plastic parts)

Glue

Step 2: Desassembly DVD/CD Drives

First step to start building this cnc machine is to disassemble two dvd/cd drives

and take off them the stepper motors. Use the screwdriver to open them and

take off them the rails.

Next step is to choose our base for this CNC machine. I used one surface from

remaining dvd 'garbage' stuff.

Finally we will need to find something to attach the one of the stepper-rails

vertically to our construction. (you will understand what I mean in our next step)

Watch the above image.

Step 3: X and Y Axis

In first image above you will see the Y axis of our CNC machine. Attach it on

your surface, in this part you will need some screws and nuts.

In second image you will see the X and Y axis. The X axis is attached to two

plastic parts that I took from remaining 'garbage' stuff. I cut it to fit the

construction.

This is an easy procedure. Just make sure to put the Y axis straight to CNC

base and the X axis vertically in this (90 degrees).

Step 4: The Z Axis

That's the most difficult part of our construction.

You will need something to attach it on X axis, a flat surface. On that surface you

will attach the servo motor (Z axis) and the pen base. Pen (or pencil) must be

able to move up and down with the help of servo motor.

Watch the above image to understand what you need to do to duild Z axis.

Tip! Use your imagination ;)

Step 5: Paper Base

Now you will have to attach a wood (or plastic) surface on Y axis (5x5cm will be

fine).

On this you will put the paper piece to print your texts or images!

Remember, printing area is 4x4cm.

Step 6: The Circuit

Now that we have our contraction ready, it's time to build the circuit and test

stepper motors (X and Y axis).

Watch the above image with breadboard circuit schematic.

Steppers motors wiring is something that need patient. On next step you will find

a 'testing' code for x and y axis. If yours steppers doesn't work properly you must

find correct working combination by changing the cables between them and the

L293D ICs.

On mine cnc, X axis motor connection are: L293 A: Pins 1 and 3 & B: 2 and 4,

but on Y axis motor connection are A: 1 and 2 & B: 3 and 4.

Step 7: Testing X and Y Axis Movement

Here is the X and Y axis testing code embedded using codebender!

For X axis:

 Clone & Edit (/? referrer=mi.vasilakis)  Download (https://codebend referrer=mi.vasila  Edit

Please select a board #include <Stepper.h>

const int stepsPerRevolution = 20; //Connection pins:

Stepper myStepperX(stepsPerRevolution, 8,9,10,11); void setup() {

//Set speed:

myStepperX.setSpeed(100);

//max 250 steps for dvd/cd stepper motors myStepperX.step(160); delay(100); } void loop() { } 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

To program your Arduino from your browser, install the codebender plugin or app. Learn more (https://codebender.cc/static/plugin).

For Y axis:

Test_Y_Axis_CNC_Plotter ( https://codebender.cc/sketch:146943?referrer=mi.vasilakis) by mi.vasilakis (https://codebende r.cc/user/mi.vasilakis?referrer=mi.vasilakis)

if you don't, try to change the cables...

Step 8: Uploading the CNC Code

Here is the main CNC code embedded using codebender!

In this part you will see your pen goes up. If don't, change penUp and penDown

variables that controlling the servo motor.

Press the "Run on Arduino" button and program your board from your browser!

What is gcode?

Gcode is a file with X,Y and Z coordinates. Header of this file is set to:

M300 S30.00 (Servo down)

G1 X10.00 Y10.00 F2500.00

G1 X20.00 Y10.00 F2500.00

M300 S50.00 (Servo up)

Download Processing from here (https://processing.org/), now donwload and

open GCTRL.pde application.

Click the "play" icon/button to start the program.

---Update!

You can use gctrl.exe, find files on 'gctrl exe for windows.zip' file.

---~Watch the above image~

Now press 'p' and select your Arduino serial port.

Press 'g' and select the 'drawing.gcode' file

(If something goes wrong, press 'x' to stop the plotter)

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 here

(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

(https://github.com/martymcguire/inkscape-unicorn) with installation notes.

Setup Inkscape for first use

Open the Inkscape, go to File menu and click "Document Properties". See the

1st image above and make the changes, make sure to change first to "cm". Now

close this window.

We will use the area within 4 to 8 cm. See the 2nd image above.

How to print texts

Put text, change font to Times New Roman and size to 22. Now click on cursor

icon and center the text like the 3rd image above. Select Path from menu and

"Object to Path".

This is more difficult than texts. Images must have a transparent background.

Drag and drop the arduino logo image (download it from files) in Inkscape. Click

ok to the next window. Now you have to re-size the image to fit our printing area,

see the 4th image above. Click Path from menu and "Trace Bitmap".

Make changes as the 5th image above. Click ok and close the window. Now,

move the gray scale image, and delete the color one behind it. Move the grey

image to the correct place again and click from Path menu "Object to path". The

6th image above show how to delete image outline.

Export as gcode

Final, go to file menu, click save as and select .gcode. Click ok on next window.

That's it! Ready to go! Use the gctrl.pde app to print the gcode file on your new

Arduino CNC Plotter!

I will make a video on next days about this procedure because it's little

complicated. It took me a lot of time to understand how it's working...

Step 11: Well Done!

You have successfully completed this tutorial and you have your own CNC

Plotter on your desk!

I would like to see photos of your CNC.

I hope you liked this, let me know in the comments.

Sdyasin,

start by checking your connections and polarity

Run a blink led code on Arduino before uploading main code

then voltages

Then continuity of motor

Also, try not to put too much load (weight) onto the motors

Very good! I thins that you can do it, but I can't help

you how...

Thank you for the photo!

this is my plotter. for Z axis I've used a rail of an other cd drive, modified with a

spring. for the moment I use a pencil because it is the smaller marker I've got

but I'll buy a pen with the tip of 0.5 mm.

If I change che numers on gctrl program I think i could modified only the write

speed... I believe it's somethingh connected whit Inkscape...

Hi, very, very good project, I see that many people have been successful.

I have uploaded Test_X_Axis_CNC_Plotter and Y, and my engines have good

movement.

I have a problem with gctrl.pde and gctrl.exe, but I do not know why. My

engines have no movement with gctrl. Select the serial port (OK), use the

arrows and no movement, load a gcode image with (G) and no movement. I do

not know where the problem is.

You help me? Thank you

Did you solved the issue?

I swaped axes to fix thath issue. And with inkscape and customized

drawings on my first attempt I had to redefine the drawing area

dimensions, making it smaller and starting from negatives points as origin

and doing the are smaller and starting drawing on the center position

(manually set)

Wish it helps :)

hello

i need help. dude i made one of this plotter and i use arduino uno and 3

easydrivers to control the motors. but when i use grbl controller the only motor

that move is the X axis .the Y axis only jogging and Z axis dont move at all. i

measure the power pins on the easydrivers and its shows 4.6 volts. i dont know

what should to do. pls help me.

Hello, greetings from Bangladesh. I recently made a cnc

plotter. But I can't generate any gcode files using inkscape. Can you

please provide me with some gcode files? Thanks in advance.

Hi;

Will your guide work with an Arduino Nano? The reason I ask is because I have

been following this guide: https://www.youtube.com/watch?v=2VFOU-WUQIY

is linked.

It has taken me ages but I think I now have the software working using gbrl and

Universal Gcode Sender but my motors are not moving (possible wiring or

arduino sketch problem as I am still not sure I have installed gbrl properly as

there does not seem to be anything in sketch apart from all the include files).

Thanks

Hi;

is gctrl.pde the file to use from within gctrl.exe?

Also is there a version of gctrl for sending gcode to the arduino for a Mac or

Raspberry Pi?

Thanks

I don't know, if you still have this problem. I had the same

yesterday. You have to check the permissions of your unicorn directory. If

you copy it with root you have the wrong ones.

Step 1: What You Will Need

For this project you will need:

Part list for beginners:

Arduino uno

Breadboard

2x L293D ICs Motor driver

Mini Servo Motor

2x DVD/CD Drives

Part list for 'pro' :

ATmega328p (with Arduino Bootloader)*

28 pin DIP IC Socket

16MHz Crystal Oscillator

2x 22pF and 1x 100nF capacitors

10K resistor

USB to Serial adapter**

Mini CNC Plotter - Arduino Based

2x L293D ICs

Mini Servo Motor

2x DVD/CD Drives

Prototyping PCB Circuit Board Stripboard

4x 2pins Screw Terminal Connector (or 2x 4 pins Screw Terminal

Connector)***

*You will need also an Arduino UNO board to program the ATmega328 micro

possessor

**USB to Serial adapter will allow the circuit to communicate with the computer

through the USB cable, just like Arduino uno does.

***Why to use screw terminal connectors? Because you don't want to solder and

desolder cables from stepper motors until you find the correct working

combination.

Tools (only for 'pro' part list):

Screwdriver
