2.  INTRODUCTION
 OBJECTIVES
 METHODOLOGY
 SOFTWARE AND CODING
 HARDWARE DESIGN OF CNC PLOTTER MACHINE
2

3.  COMPUTER NUMERICAL CONTROL(CNC) Plotter is a special
type of printer that uses a pen to draw images on solid
surfaces using logical instruction interfaced with a computer.
 CNC plotter machine is a 3D controlled 2D plotting machine
it can be used for PCB design ,LOGO DESIGN etc.
 In this project we are using very low price spare parts to
design a CNC plotter.
3

4.  The objective of the project is to design and implement a
CNC plotter machine drawing surface area is an A-4 size
which will be in a solid surface.

5.  A CNC plotter is able to draw complex line drawings . The
coordinates are uploaded to the machine controller by a
separate program and the image file transformed to the G-
code via software then this code transfer to the controller by
which the mechanism is instructed to draw the image.
 We are making CNC with the help of ARDUNIO based design
using ATMEGA MICROCONTROLLER.
 Machine have three motors to implement the X, Y and Z
axis .

7.  For making CNC plotter two software are used
1. INKSCAPE
2. FRITZING
 INKSCAPE –
This is the software which is used for the designing the
plotted diagram or text in which the software G code file of a
selected image or text is created G code is commonly used
when X,Y and Z coordinate are used .
 FRITZING –
It is friendly open source circuit simulator software which is
mainly used in PCB design.

10.  BRESENHAMS LINE ALGORITHM is used in CNC plotter by it we
can control the stepper motor in X, Y and Z direction.
10

11.  The two dimensional mechanical design of the body of CNC
has to be made by using
 Stock material
1. wood
2. PVC board
3. metal rod
 COMPONENTS required
1. stepper motor (2pieces) - 3 to 6 volts
2. servo motor – 4.8 volts
3. power supply – 12 volts
4. arduino uno (R3)
5. pen
6. clamps
7. connecters and cables
11

12.  The pen of the machine can be replaced by a laser to make it
work like a cutting machine
 The pen can be replaced by a powerful drill so that it can be
used for both milling and drilling purposes.
12

13.  This project is about building a machine prototype of a CNC
plotter machine which is able to draw a PCB layout.
 This is a low cost project as compared to other CNC product.
 The machine is designed with a very simple construction
scheme and can be carried anywhere without much effort.
 The pen can be replaced with a pinhead or laser head or any
other tool for different purpose of use.
