I am documenting how to build a simple structure for a 2 axis CNC.
I've used 2 DVD-ROM drives for the stepper motors (I'm assuming about 23 steps/revolution). (pictures below)
The motor driver is adafruit motorshield . It uses H-bridge for steppers so it's not supported by grbl directly.
You 'll need other software to communicate the CAM software with arduino.
STEPS:
- Load CNC controller program into arduino.
 - Design your model.
 - Generate GCODE
 - Transmit GCODE to Arduino
 - MOVE!!
 
Now, the links with the software for each step:
- GCodeCNCDemo ( https://www.marginallyclever.com), for compiling you'll need this library (AFMotorDrawBot).
 - I'm using a VERY simple gcode generator for 2 axis works online in HTML5. Here
 - It's generated by the above http://simplegcoder.com/
 - Transmit the code so GCodeCNCDemo understands it with GCodeSender. (Dan-Marginallyclever)
 - Move (VIDEO)
