The Shapeoko 2 is fundamentally the same as a Shapeoko 1 --- just adds some upgrades and improvements. One in-depth examination of this is Adam's upgrading of his machine from v1 to v2: http://sheekgeek.org/2014/adamsheekgeek/my-shapeoko-version-1-to-version-2-conversion-adventures or see http://www.shapeoko.com/forum/viewtopic.php?f=5&t=5743 or http://www.cnczone.com/forums/diy-cnc-router-table-machines/211442-cnc-software.html
Unfortunately, the Shapeoko 2 is no longer available. Please see instead, the new Shapeoko 3.
A list of assembly videos is on this page.

Kits and parts and accessories are available from Inventables.
The initial announcement of the SO2 blog announcement included a preliminary B.O.M. (bill of materials) --- this has since been updated and is on the wiki: BOM. Initial list of possible features for the second version were at Mark II.
Nice set of photographs on a European site: ShapeOko2 cnc fräs/gravör byggsatsmontering.
While the SO2 incorporates many upgrades from the initial iteration, there are still upgrades to be made. Some of them are documented as columns in tables on the B.O.M.. Official ones here: ShapeOko 2 Upgrades.
The first documented ones are:
- Z-Axis ACME Upgrade --- mentioned on the B.O.M., Acme screw Z-axis for ShapeOko 2 --- photos by User:Improbable Construct in ACME upgrade pictures for NEMA 17 install
- Z-Axis NEMA 23 Mounting
- NEMA 23 Z-axis for shapeoko 2 (see also NEMA 23 and ACME Z Axis upgrade and Re: Carl's build log and especially his documentation of this here: User:Carl_Fisher#Phase_2_-_Building_and_Modification)
- Z-Axis NEMA 23 Mounting
- NEMA 23 motors for the X- and Y-axes --- specifics are documented on the B.O.M. --- there's also Inventables blog: Upgrading your Shapeoko 2 with NEMA 23 motors
- Makerwill's ShapeOko 2 Build Log --- eschews Dual Motors for a Drive Shaft.
- Yet another work holding thread --- how to cut holes for T-nuts into the wasteboards.
- Aluminum T-Slot Bed --- Replace the wood spoil boards with two extrusions.
- Addressing limited Z-axis travel
- Shimming out the spindle mount to improve the Z-axis travel: Re: Z-travel on Shapeoko 2 --- see also http://www.instructables.com/id/Shapeoko-2-Z-Axis-Fix/

Implemented SO2 Upgrades and Notes
Double Makerslide X-Axis
The ShapeOko 2 includes a version of the Double Makerslide X-Axis --- as noted on that page, it is a simplified version and the rails are not connected. This can allow them to twist under load, which has been found to potentially cause difficulties on scaled up machines, esp. when one upgrades the spindle. Unfortunately, there is as-of-yet no consensus as to the best way to fasten the rails together --- there are a number of options which have been discussed on the forums, and it is to be hoped that some elegant solution will be found presently.
Also now standard are Dual Motors.
The Z-axis is also different. Discussion of this here.
- Y-Axis gantry flip (gain +/- 1-1/2")
- Another option would be to re-arrange the Z-axis to be like the Shapeoko 1. This would require drilling new holes.
- Move the wasteboard to the bottom and add a spoilboard in its stead
PDF assembly instructions
In case docs.shapeoko.com isn't accessible, here are (low-res) .pdfs automatically created from those pages:
This is a temporary measure until some better arrangement is made for the instructions. These .pdfs have not been up-dated w/ the latest changes and only have the low-resolution web images in them, not the higher-resolution / larger images one can access on docs.shapeoko.com by clicking on the non-thumbnail images --- please do not use them unless you have no other recourse.
