HOW TO MAKE HOMEWORK WRITING MACHINE

Homework writing machine is automatic writing machine use for the typing any type of text and drawing any design on paper. Homework writing machine is working like a CNC machine. This Machine is working on 3 axis (X, Y, Z).  This three axis motion is given by stepper  motor and servo motor. In this blog I show you how to make homework writing machine at home step by step process guide. If you have any problem than comment at last.

Take piece of wooden ply and make frame for X and Y axis  gantry. As per above picture cut and drilled wooden ply and stick together with the help of glue gun.

STEP : 3 MAKING X- AXIS GANTRY

Insert the stepper motor in the hole of wooden frame. As per above picture insert screw and pencil inside the hole. This screw is provide the sliding movement to pen so we can draw anything with the help of this machine.

STEP : 4 STICK X AND Y GANTRY TOGETHER

We need to make two same gantry X and Y. Now Stick X gantry to Y gantry as per above picture. After that your machine is ready to work in XY horizontal surface.

Now we require to make z axis for pen movement.  This was done by servo motor.

STEP : 5 CONNECT SERVO MOTOR

Take glue gun and apply on X axis gantry as per picture. Stick servo motor on X axis gantry as per Picture (Shaft of servo motor should be outside).

STEP : 6 FLEXIBLE NIB-PEN MAKING

PEN, SPRING PEN, SPRING PEN, SPRING PEN, SPRING

To make z axis we need that pen must be flexible to up and down.

  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

STEP : 7 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 : 8 TAKE ALL CIRCUIT

Stepper Motor Driver connect on Expansion Board A 4988 Driver module. Then this combination connect on Arduino Uno R 3 (As per circuit Diagram).

STEP : 9 WIRING

circuit

  • Place 12 Volt DC Battery on Back side of XY axis Gantry.
  • Place Combination of all circuit (2 PCs  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.
  • Attach X and Y axes Stepper motor on Expansion Board A4988 Driver as per circuit diagram.
  • Connect servo motor as per circuit diagram.

STEP : 10 BEN-BOX SOFTWARE CONFIGURATION

benbox software

Download ben box 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
  • #First Page

  • Serial Port : COM(3,4 or 5)
  • Pen Up : 35
  • Pen Down : 22
  • Speed : 800(you can increase)
  • Time : 200
  • Step: 1
  • Curve mode : Outline
  • Select bullet : Curve
  • Select bullet : Servo
  • #Second Page

  • Step : x=2 y=3
  • Dir : x=5 y=6
  • Min : x=-1 y=-1
  • Max : x=-1 y=-1
  • Ppm : x=320 y=320
  • laser : 0=12 1=12
  • Servo : 0=11 0=12
  • Feed Ra. : 1500

Write anything on Screen And Play to write on book.

  2. Good evening sir
    Congratulations for your brilliant achievement, I am subscribed in your channel and I am always very impressed by all your achievements.
    however, I have a small question please. I did not recognize the 6 small pieces that you put on the pins of the V3 board just before putting up the two modules A4988 (on the video timing, from 5:19 to 5:34).
    thank you so much in advance for your answer sir.

  3. I have problem with banbox how i can change direction of servo motor?When I want to lower the pen, he rises the pen,what is problem?

  4. Hello Admin. I need to replace the battery to an adaptor. If I’m looking for a 12v adaptor, will it work? Also how much should be the output current from the adaptor? It’ll be really so much helpful if you reply. Thank you.

  5. Can you specify all the parts for this build please? Some parts are used which I don’t know the names of.

  6. Great work Creativity Buzz, I am planning to make this project please help me out.
    In video it only draws squares , I hope that it can write and draw other objects as well. And how much is its speed in reality is it quick or is it slow , like writing a page takes how much time. And does the motor heat up after working for short time , or it can work non stop for hours. Thanks and all the best for future projects.
