Shapeoko II
A summary of improvements include:
- Stock 500mm MakerSlide rails
- Stock open front/back sections to allow for longer material
- dual drive by default
- plate configuration to accommodate multiple wheel sizes/types
- work envelope increased from ~200mm x ~200mm to ~450mm x ~450mm
- X/Z-axis SIGNIFICANTLY more rigid (examination of the trade-offs on the flipped Z-axis)
- GT2 belting
- more elegant belt clamping solution, cleaner belt routing
Features which made it:
- inverted belts
- open end plates
- reconsider MakerSlide lengths for most efficient usage of material
- all metal spacers
- double X standard
- shorter bolts for V-Wheels w/o eccentric spacers --- check all bolt lengths
- re-work standard carriage plate to be steel
Features which were obviated:
- zip ties for belt anchors
- all belts on the outside

Shapeoko Next Generation
Features for next time:
- re-work belt routing / holes / plate sizes so that the X-carriage doesn't run into the idler wheels[1]
- all metric hardware
- reduce M5 washer count to below 100 to make kitting easier
- add lock washers where appropriate
- use motor w/ Acme screw shaft for Z-axis
- Acme driven Z-axis
- integrated work-holding (this is addressed by the Inventables: Waste Board with Threaded Inserts)
