This is the 3rd official version of the Shapeoko desktop CNC machine. With over 3 years of user feedback, experience, and improvements ranging from easier assembly to better software options, this is the best Shapeoko we've ever made. Period.
An Open Hardware project in Dixon, IL by Edward Ford
Ayo! If you're looking at this project, you probably think a low cost simple desktop CNC machine is as cool as we do. Sweet. It's always nice to meet like minded people!
The Shapeoko is a 3-axis CNC machine kit. It is intended to provide basic functionality while being simple to understand, assemble, and operate --- all this at the lowest possible price. The stock configuration forgoes many features that are standard in more expensive machines (but many can be added as upgrades). This imposes limitations that the user has to work around. Despite this, or maybe because of this, many people with no prior experience with CNC, woodworking, or machining have successfully assembled and operated Shapeoko machines. Like most things in life, what you get out of it reflects the effort, preparation and patience you are willing to exert. We strongly suggest that you start by assembling and using the machine in its stock configuration. This makes troubleshooting via e-mail and the forums easier; more importantly, it provides you with valuable experience for implementing any planned upgrades.
Have a look around the DIY CNC scene and you will notice the lack of simple, low cost, straight forward build options. We want to fix that. For the last four years we have been designing, redesigning, and building what we hope to be a CNC machine that anyone can build for the lowest possible price (about $300 in 2012--3 with a bit of patience and luck in sourcing parts and w/o two upgrades (dual-motors and double X-axis) which are now standard, a full kit (sans spindle) for the much improved Shapeoko 3 is currently $999). Did I mention that cost even includes the electronics to run the machine? Unlike other projects where you're shelling out $1,000 for just the frame and maybe motors, ShapeOko includes everything you will need to turn your ideas from just a crazy thought into a tangible item.
If nothing else, this project is open. Nobody wants to get locked into some proprietary platform, and nobody wants to spend their money on a machine just to learn they will need to spend another $500 on software to run it. With that in mind, we built the entire process around open source components. From CAD and CAM software to the CNC controller; every step has an open source solution. Did we mention the entire project itself is open source? Every nut, every bolt, every belt, fully documented with part numbers and vendor list. Do with it as you please!
What makes this different? One of the frustrations we had with other designs was the fact that you had to visit a lot of different vendors in order to get all the pieces. We didn't like that. Plus, some projects didn't have a central "released" build, which made it difficult to determine if what you were building was actually what you were expecting to build.
All of that resulted in the following design goals:
- 1 standard design
- lowest possible total cost (originally $300)
- Maximum of 3 vendors
So, how are we doing on the goals?
- 1 standard design - So far, so good. There are documented upgrades, but a single design for each version.
- lowest possible total cost - while there are less expensive machines, as of this writing the Shapeoko seems to be at the sweet point of price and capability and expandability.
- Maximum of 3 vendors - as of this writing it's possible to purchase a full kit from single vendors, Carbide3D (the manufacturer) or SparkFun (which uses a fully opensource control board, and offers the option of a mechanical-only kit) (note that it requires a code to be supported by Carbide Motion). See the Parts page (as well as the Shapeoko 3 bill of materials) and Vendors pages for more information and other options. https://www.sparkfun.com/distributors
How to determine if a Shapeoko is right for you
Please look through the wiki, esp. the Project links and see if the machine is capable of the sort of projects which you wish to make. Check the Materials page to see if it can cut the materials necessary for your projects.
Research CAD/CAM workflows until you are confident of a suitable technique for getting from: idea -> design on computer screen -> G-code file -> stock clamped, machine zeroed, file sent -> finished part.
The prototypical first job for a Shapeoko is to cut a coaster --- doing this using Carbide Create: http://community.carbide3d.com/t/lets-make-a-coaster/4203
3D Machine Simulation
Forum user Grblgru has created a 3 dimensional software simulation of a Shapeoko (which can be extended to mimic other machines). This will allow one to do an end-to-end simulation of a production workflow, including (virtual) machining operations. In addition, it's a great way to while away time while waiting for a machine to be delivered.

Descriptions of Learning to Use a Machine
To a great degree, this wiki represents the community's experiences of what it's like to learn:
- how to assemble and calibrate a machine
- how to design and draw up projects
- how to source, prepare, clamp, and zero stock and determine optimal feeds and speeds
- how to use the machine, zero and fine tune it
One user, JohnP, wrote up an excellent summary of his experiences on the forums: Copper sign.
This wiki documents the Shapeoko, a CNC machine / kit project. The wiki is navigated by using the sidebar to the left. The overall structure and some of the more interesting pages:
Getting started in CNC
Lastly use the machine to make Projects of suitable materials (clamped in place w/ a suitable workholding technique) using your choice of software (one tool for this is Carbide Create). Note that one should test and prove out the machine, the CAD/CAM file and feeds and speeds systematically. Start by cutting in foam or some similar material, progress to making cuts in scrap or inexpensive materials. Only commit to using expensive materials when confident of everything working correctly.
The classic first project is a coaster:

- Parts --- Overview of different parts and components, additional information on: Belts and Pulleys, Electronics, Microcontroller, Stepper Motors, Spindle Options and Mounts and Endmills
- Using Your Machine --- Workflow, Calibration and Squaring the Machine, Fine Tuning, Workholding
- Gallery --- Hello World
Much information about the original machines is still present here and has been archived (see Shapeoko 2 and ShapeOko 1 Build Instructions in the sidebar) and these pages serve as a catch-all for anything not covered at Project ShapeOko (news and updates, SO3 assembly instruction link and main link repository), the Project Gallery, and SO2 assembly instructions hosted on github.com) and the user forums.
