Introduction: DIY Arduino Mini Laser Engraving Machine

About: Electrical engineer by profession

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

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

Step 5: Results

I have made a dice from this 3D printer

and do some engraving on wood it turns out very amazing
