Product Information

The kit is out of stock until we get the laser-cut parts from the fabricator. We expect to have it back on 7 September. Please check the blog for updates. You can also reserve a kit using this form.

Larger kits, and kits with open end plates are available.  Choose the Configurable Size eShapeOko and select your desired size.

The eShapeoko is a low-cost CNC milling machine, the smaller sizes of which are suitable for desktop use.  It is also a generic three-axis cartesian movement platform with numerous uses beyond milling, and it is incredibly easy to expand and upgrade.  It is also available in a fixed size with solid endplates (the original version), until the stock of those end plates runs out.

The eShapeoko is based on Edward Ford's Shapeoko, with numerous changes and improvements that bring it to the same level of performance as Edward's Shapeoko 2.  Shapeoko is an open-source project.  Thank you, Edward!  The low-cost aspect, while retaining precision, is thanks both to Edward's hard work in refining the design, and to Bart Dring's brilliant linear motion system, MakerSlide.  Thank you too, Bart!

More about the kit, including the assembly instructions and the list of parts, can be found on the wiki.  Drawings for the custom parts are available on GitHub.

This is the standard size kit (375 mm X axis, 500 mm Y axis) with the original end plates.  For open end plates and a selection of sizes, please select the eShapeoko with Open Ends, Configurable Size.

With the dual-X upgrade option, you will get four extra V-wheels, as well as all the spacers, washers and bolts needed to build a wider X carriage that slides on two back-to-back MakerSlide rails.  The two X rails can be bolted together, but no fasteners are included for that (it makes only a small difference at the standard X size anyway, but it becomes much more useful for wider machines).  For dual-X machines, the X carriage can be upgraded to aluminium spacers.  Aluminium spacers are not available for single-X machines, as the benefit is not significant.

The original Z axis configuration uses a M8 x 1.25 threaded rod, 150 mm long, with an acetal (Delrin) leadnut.  The threaded rod is secured to a bearing with two M8 nuts.  The leadscrew upgrade uses a Tr 8 x 2 "metric ACME" trapezoidal leadscrew, 175 mm long, also with an acetal leadnut.  The threaded rod is permanently attached to the bearing.  It is supported only at one end, same as the M8 threaded rod, but an option to support the other end will be available in the future.  (The leadscrew is longer than strictly necessary and the free end is ground down to 5 mm for this purpose.  The only advantage of supporting both ends is that the Z axis can be driven faster without the screw whipping.)

This is a mechanical kit only.  It includes the belts, the belt pulleys, and the hardware to attach the motors, but it does not include stepper motors, nor any control or driver electronics.  Basically, if it's mechanical, it's in there; if it uses electricity, it's not.

For the Dual Y Drive option, four stepper motors are required: one on X, two on Y, and one on Z; only three (one on each axis) are needed for the Single Y Drive option.  The base model supports NEMA17 motors with 5 mm diameter shafts, and includes M3 fasteners and spacers and 5 mm bore  belt pulleys and flexible coupler.  You can choose to replace these with M5 hardware suitable for NEMA23 motors, and 6.35 mm (1/4") bore belt pulleys and flexible coupler.  You can choose to upgrade only the X axis, both X and Y, or all three axes.  In our opinion, a NEMA23 motor on the Z axis is almost never necessary, but we caved in to popular demand.  A larger Z motor mounting plate will be supplied to accommodate the footprint of the NEMA23 motor.

If you choose the NEMA23 motor hardware, you will get two mounting options for the X motor: almost flush against the mount plate, much like the NEMA17 in the instructions, or on spacers with the belt on the outside, like the Y motors.  Hardware and belt anchors are included for both options, so you will have a few parts left over.  Instructions, pictures and more information to be updated soon on the wiki.

Please note that the MakerSlide and the belt tensioners come with the holes untapped.  You will need an M5 x 0.8 tap and a suitable handle.  Other than that, only common tools are required: 8 mm spanner, two 13 mm spanners (or two adjustable wrenches, or a vice and a spanner, etc), Allen keys from 1.5 mm to 4 mm, a small piece of fine sandpaper for metal.  For adjustment and calibration, you'll need a long ruler or a tape measure, and, ideally, a set square and a digital caliper.

This is a kit, not a finished product, and you are responsible for your safety and the safety of others during its assembly and operation.  Please use sensible precautions.

FAQ

If you have a question not covered here, please use the Contact Us link at the bottom of every page in the store.

This FAQ is under construction; please bear with us while we add links and images.

Q: Is this the same kit as the one sold by Inventables?
A: No, this is our own kit.  We are not affiliated with Inventables or with Edward Ford.
 
Q: Is eShapeoko a Shapeoko?
A: This is more of a philosophical question.  See this discussion.  eShapeoko is largely the same as Edward Ford's Shapeoko, with the same brilliant economy of design, but it includes a number of changes.  Some come from Edward himself, some from the most excellent community, and a few are our own ideas.
 
Q: What does the "e" stand for?
A: "European", initially.  Now it also means "enhanced" and "extended".  We'll let you decide whether we deserve "excellent", "extraordinary" and "fabulous".
 
Q: But there's no "e" in "fabulous"!
A: You're right, there isn't.  We got carried away.
 
Q: What are the differences between eShapeoko and Edward Ford's Shapeoko 1 (the old Inventables kit, no longer available)?
Q: What are the differences between eShapeoko and Edward Ford's Shapeoko 2 (the current Inventables kit)?
A: By the way, we think that all the differences between eShapeoko and Shapeoko 1 are improvements.  The eShapeoko and the Shapeoko 2 are about evenly matched, although each has some better parts compared to the other.  Please read more on the wiki.
 
Q: What is the same?
A: Overall design.  Makerslide.  V-wheels.  Idlers.  Open belts on X and Y, M8 allthread as Z leadscrew.  Choice of NEMA17 or NEMA23 motors for X and Y, NEMA17 on Z.  This is still Edward Ford's machine, with all his experience that went into its design.  We just added a few personal touches.
 
Q: If I get the dual Y drive upgrade, how do I connect the additional motor?
A: The simplest way is to use the GAUPS, which has four drivers, two of which can be connected to drive the Y axis.  If you have only three drivers, you can connect the Y motors in parallel to one driver.  Or, if you have a board with four (or more) drivers and firmware that supports this, such as the TinyG, you can map two drivers to the Y axis.  LinuxCNC also supports mapping more than one set of outputs to a given axis.
 
Q: Do you sell the motors or the electronics?
A: Yes, we have motors, drivers, driver shields, power supplies and so on.
 
Q: What about limit switches?
A: We sell limit/homing switches which are compatible with our motor plates.
 
Q: Can I use the eShapeoko for things other than milling, such as 3D printing?
A: Yes!  Of course, you'd need a print head, and possibly a heated bed.  See the Shapeoko forum for many ideas.  We like the Wade extruder with Greg Frost's modifications ("guidler", herringbone gears) and the J-Head Mk V-B hot end by Brian Reifsnyder, but options abound.
 
Q: Can I use RAMPS (or other 3D printer electronics) to drive the eShapeoko?
A: Yes!  However, the usual eShapeoko drivers run at 24 volts, while RAMPS runs at 12 volts.  You won't get the same speed and torque, but it will work reasonably well.
 
Q: Are the parts really blue, green and yellow, as in the model?
A: No.  The parts are bare stainless steel, not finished in any way (mill finish).  Feel free to paint them, or use a belt sander to give them the brushed stainless steel look.  Send us pictures!
