Summary

The following is a comprehensive list of all parts required to build the standard version of the ShapeOko cnc mill. Some parts such as nuts, socket head cap screws, washers, and wires are commodity parts found in most hardware/home improvement stores. Other parts, such as [stepper motors], [stepper drivers], [power supplies], or [microcontrollers] are less likely to be found in a local store, and will probably have to order from the online suppliers. Other parts, such as the [front] and [back] frame plates and the [motor mount plates] were designed specifically for this project and are custom manufactured.

Part availability and clarity are two focuses of the ShapeOko project. This page is your resource to find the descriptions and sources for each part you will need in order to build a ShapeOko mill.


ShapeOko Assemblers Pack

Many of the parts are available in the ShapeOko Assemblers Pack.

Electronics

E1 Stepper Motor 58 oz-in, Nema 17 Sparkfun 3
E1.JPG
The Shapeoko can use Nema 17 or Nema 23 stepper motors. The 58 oz-in motors listed are sufficient to drive the Shapeoko, but larger motors can be used.
E2 Power Supply 24V 4.2A 1
E2.JPG
The size of the power supply should be at least 4.2A at 24V. A larger supply (for example, a 4.5A) will work fine. The size is based on the requirements of the stepper motors you choose.
E3 Stepper Driver Pololu A4988 compatible Pololu 3
E3.JPG
The stepper drivers that the Shapeoko is designed to use is the Pololu A4988. There are other drivers that are compatible, including the Pololu-compatible open source Stepstick.
E4 Arduino 328P Compatible Seeeduino V3, Arduino Uno R3, Diavolino, others 1
E4.JPG
Any Arduino 328P compatible board should work. Multiple vendors sell these boards, and price varies by vendor and features.
E5 Arduino stepper shield 2.7 in x 2.1 in
(standard Uno shield size)
Reactive\Substance. Buildlog 1

(Revision 1 board shown)

The Shapeoko was designed to use the Pololu stepper drivers, and this Arduino shield makes assembly and wiring very easy and straight forward. Another option is to create your own board. A good example of this is User:DrRob, who has made his own shield using perfboard.
E6 AtomCNC 97.8mm x 95.5mm (inches: 3.85" x 3.76") AtomWiki 1
Atomcnc.jpg
(Revision 1 board shown)

Using the AtomCNC makes the whole wiring and usage of the Shapeoko fairly simple. The AtomCNC includes the Arduino + Sheild + Controllers in one setup and 1 PCB with a optional 50mm fan mount. Also include a 10A @ 240VAC relay for rotary tool ON/OFF control. Homing/Limit I/O and GPIO for future use.
