Introduction: DIY Arduino Mini Laser Engraving Machine
Hello guys in this post I have build a CNC engraving machine
Using Arduino nano, stepper driver, 1W laser module and custom made PCB
I have designe and order PCB from JLCPCB.COM
JLCPCB Prototype for $2(Any Color): https://jlcpcb.com

Step 1: Video
Step 2: Material Required
Arduino nano :- http://amzn.to/2zgmRwU
L293D IC :- http://amzn.to/2BmWqaL
PCB Terminal :- http://amzn.to/2BPuUUq
Header pin :- http://amzn.to/2BPuUUq
Laser module :- http://amzn.to/2BPuUUq
Step 3: Circuit Drawing
As per the circuit drawing I design PCB
The is separate circuit for laser module A 2222a transistor is used to turn on/off laser from the digital output of arduino on pin 10
Step 4: Software
Link to download laser GRBL software
https://github.com/arkypita/LaserGRBL
Link to download arduino code and processing code
Step 5: Results
I have made a dice from this 3D printer
and do some engraving on wood it turns out very amazing
