They represent a significant leap forward in terms of functionality and ease of use, offering a solution to many of the issues that have traditionally plagued servo motors and controllers.

Created using 3D printer parts, a handful of stepper motors, and an Arduino Nano development board, the wire bending machine can be programmed to create a wide variety of different shapes and angles.

The CNC-Machine Instructable, created by the folks at CNC World, is fairly straightforward. You take apart a DVD player and then use the case to create a sort of platform for the system.
