Introduction: Homework Writing Machine
FOLLOW US ON OUR WEBSITE :- http://www.creativitybuzz.org/
Hi guys , As per the title this is a simple project using Arduino to make Homework writing machine at your home.This machine can draw any design and write any type of fonts.You can see sharpness and perfection of writing in photos.
The machine uses a gantry to move the writing tip along the X and Y axes. The flexible-nib pen is mounted on a servo motor which rotates the tip onto the writing surface, taking care of the third axis.

Material To Be Used:
- 2 PCs Old DVD writer
- Sun Board 3 mm Thickness (You can use any hardboard)
- Glue (FeviQuik)
- 2 PCs A4988 Stepper Motor Driver http://amzn.to/2keC27T

Step 1: Watch Youtube Video of Making Writing Machine
Here is full video of how writing machine is work on surface.If You Like This Project Please Press The Like Button.
Step 2: Disassemble DVD Writers.
First of all you need 2 DVD writers of your CPU.You can use non workable DVD writer for this project.
Take 2 DVD writers and open 5 screw on bottom of this DVD writer.
Then open bottom case of DVD writer and disconnect all circuit.
Then open Top case of DVD writer.
Step 3: Disassemble All Parts.
After this you see rectangle part of DVD writer with stepper motor on back side.
Open 2 screw on this Rectangle and remove this rectangle outside.
Repeat this process for 2nd DVD writer.
After this you have two PCs of Rectangle Part (AS per 2nd Pic.)
Step 4: Unscrew Stepper Motor
Open one screw on sliding shaft and 2 screw on stepper motor.
Disassemble stepper motor and sliding parts from one rectangle.
Remove all circuit of sliding part and cut middle part of this sliding part.
Now you have 2 PCs of plastic part.Combine both plastic object and stick with FeviQuik.
Step 5: Connection of Stepper Motor
Take female header pin (4 pin) as a picture.
Connect two stepper motor with this 4 pin female header as show in picture(In the same line).
Step 6: Make X - Axes Gantry.
Take Sunboard sheet of 10 cm length and 9 cm width.
Take other sunboard sheet and cut this type of object.
1) 3 x ( 1cm x 10cm) combine with glue.
2) 3 x ( 1cm x 10cm) combine with glue.
3) 3 x ( 1cm x 5 cm ) combine with glue.
Stick 1st part on left side of 9x10cm sunboard sheet and 2nd part on right side of 9x10cm sunboard sheet.
Place shifting part on this sunboard sheet along X axes.
And your X axes Gantry is ready.
Sick 3rd part Parallel to shifting shaft and Stick Stepper motor with X axes Gantry.
Step 7: Connect With Y - Axes Gantry.
Take Glue(Fevibond) and apply on Y axes gantry(2nd DVD writer Stepper motor Rectangle Frame).
Take X axes gantry and stick X axes on Y axes Gantry.
Your X and Y axes Gantry are Ready.
Now Your Pen can move along XY Horizontal surface.
Now you have to create Z axes (vertical) movement of Pen using servo motor.
Step 8: Connect Servo Motor.
Take glue gun and apply on X axes gantry as per picture.
Stick servo motor on X axes gantry as per Pic(Shaft of servo motor should be outside)
Step 9: Flexible-nib Pen Making
1.Open your pen.
2.Cut top end of refill.(1 cm)
3.Take spring of any other pen.
4.Mount this Spring on top end of refill.(As Per Pic.)
5.Take some length of sewing thread and bind this thread on refill.(As Per Pic.)
6.Make hole on pen case and close this pen as per last pic.
The flexible-nib pen is Ready.
Step 10: Connect Pen
Take glue gun and apply on servo motor bigger side of shaft.
The flexible-nib pen is mounted on a servo motor which
rotates the tip onto the writing surface.
Bind Thread on servo motor shaft as per pic.
Step 11: Take All Circuit
Ready your all circuit.
1) 2 PCs A4988 Stepper Motor Driver with heat sink
2)Expansion Board A4988 Driver
3)Arduino Uno R3
First of all take hit sink and stick on A4988 stepper motor Driver.
2 PCs A4988 Stepper Motor Driver connect on Expansion Board A4988 Driver module. Then this combination connect on Arduino Uno R3 (As per circuit Diagram).
Step 12: Wiring
Place 12 Volt DC Battery on Back side of XY axes Gantry.
Place Combination of all circuit (2 PCs A4988 Stepper Motor Driver with heat sink , Expansion Board A4988 Driver , Arduino Uno R3) On Back side of this 12 volt battery.
Connect 12 volt dc battery as positive(+) and negative(-) connector.
Connect X and Y axes Stepper motor on Expansion Board A4988 Driver as per circuit diagram.
Connect servo motor as per circuit diagram.
Step 13: Benbox Softwer Configuration.
Download benbox software on your computer and connect this with USB connector.
1. Open Software.
2. Connect USB Plug.
3. On Update Firmware select COM (3,4 OR 5). and browse firmware from downloaded software.
4. Select all Value of software as per all pic.
Serial Port : COM(3,4 or 5)
Pen Up : 35
Pen Down : 22
Speed : 800(you can increase)
Time : 200
Curve mode : Outline
Select bullet : Curve
Select bullet : Servo
Step : x=2 y=3

You must give the thickness
Can u send me a diagram of the circuit or u can send block diagram
No need to use any programming???
How to give commands to it to writw
What is this??
what is it
can I have the schematic diagram circuit for this project ?
Program doesn't respond in the middle of the event. Pen stops plotting and remaining time going on increasing solution plzz
I'm loosing connection from the software.
My port is working fine.
my benbox firmware not showing comport there...
Problemwith drives install Arduino software ide
what is the name of this
Just two questions, am am building myself this project and I was wondering if i can use a 14V battery and what should the Ah be, the 14 v battery has 5000mAh, and how can i charge the batery, through the Arduino charging lot? Thank you
You don't have to put an Arduino code
is it necessary to short or leave it as it is .if we need to short what are those black things and where will i find one
Just to make sure, is there any arduino code i need to input before?
Can I please get a circuit diagram
GUd project...wish to buy one from u
I HAVE MADE THIS PROJECT BUT NOTHING IS HAPPENING I THINK I DONT HAVE THAE COADING FOR ARDUINO
WHERE CAN I GET THE ARDUINO COADING?
I've got it all working, great tutorial. However the motor makes a high pitched noise when turning on the battery and the motors run very hot within 1 minute. Is there a way to fix the overheating?
I connect stepper motor with motor driver v3 shield but it just vibrating it not moving is moter driver directive or other problem
Servo s not working please help I've constructed the circuit as shown by u
