Introduction: How to Make Arduino Based CNC Machine at Home
Make a CNC Machine from old DVD writer
Step 1: Video of CNC Machine Working
Step 2: Material Required
1)Arduino Nano x1
2)Old DVD writer x2
3)Motor Driver (L293D) x2
4)16 pin IC socket x2
5) Veroboard doted x1
or you can make pcb
6)Male header & Female header
7)Female USB (For power the motors) or you can use 9v jack
8)Female Jumper wires
9) Nuts
10) BO motor clamp
11)1 Servo motor
12) Double sided tape
13)Pen
14)Acrylic sheet
Step 3: Cutting & Drilling Acrylic Sheet
1pcs 12"x6" (Fore base)
2pcs 1.5"x7" (For X-Axis Stand)
1pcs 3"x3" (For Writing base)
3pcs 1.5"x3"(For Moving part of X-Axis & Y-Axis and also for pen holder)
8pcs .5"x,5" (For specer)
Marke for drilling then drill it
Step 4: Extract X-Axis & Y-Axis From Old DVD Writer
Step 5: Solder Wire With Stepper Motor.
Step 6: Attach 1.5"x 3" Sheet With Moving Part of X-Axis and Y-Axis by Using Glue Gun
Step 7: Make Circuit Board
Make a circuit board using Dotted vero board
or
you can design a PCB ..

Step 8: Make a Pen Holder
Cut the DVD writer Shuter Mechanism
Attach Servo and connect with the Gear
and also connect 1.5"x3" sheet with moving part and also glue the pencil compass to hold the pen...
Step 9: Assembling the Machine
Assemble all the parts as shown in Pictures ...
Step 10: Connection With Board
Step 11: Software Part
