A simple Arduino based CNC plotter.  It utilizes an Arduino Nano and three 28BYJ-48 stepper motors.  The inspiration for this project came from the Instructables article [Arduino Mini CNC Plotter](https://www.instructables.com/Arduino-Mini-CNC-Plotter/) published by [MertArduino](https://www.instructables.com/member/MertArduino/).  Which is beautiful in its simplicity and completeness.

My modifications:

• Modified the axis channels to avoid overhang.
• Changed the motor mounts for more flexibility in motor positioning.
• Changed the racks so they can be flipped to reverse direction.
• Added strain reliefs to protect the wires on the steppers.
