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.
Step 8: Connect Servo Motor.
Step 9: Flexible-nib Pen Making
Step 10: Connect Pen
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
Step 13: Benbox Softwer Configuration.
Step 14: Watch This on Youtube.
