This project adds a bolt on, no firmware modification required fully supported Y axis to the Lulzbot Taz 3, 4 and 5 printers in place of the existing bearing rods. This project is compatible with the layout of the Taz 3. You will need to drill 4 highly precise holes in a new or existing Taz 3-5 heated bed mount plate to accommodate the Openrail hardware.

If you downloaded the 1.0a version of the corners, they were 4mm too tall at the very tip. You can easily cut that off without affecting the part, or download the corrected 1.1a variant and reprint it.
The new Version 2.0 parts move the rail outboard 1mm per side to better engage the wheels.
Update 2:
The two Idler and Motor endplate reinforcement plates are designed to allow for easier rail allignment in parallel. The first release was off a bit, Version 2.0 is corrected, pictures to come shortly, You will need to tap the end of the Openrails with an M5 Tap to be able to use these plates (the two outside holes on the front and all 4 holes on the back), and they should be considered optional.
The other addition is an optional Combined Drill Guide. It has the spacing set between the small fixed and large exxentric holes fixed. It's a thicker plate, which will hopefully make it more effective. it also has smaller holes for the bolts, so it shouldn't be able to move around as much anyways. This one does use significantly more plastic than the other ones, but it should thoretically be easier to use. You'll want to print two of them and make sure they both line up when you drill your holes. The X allignment (side to side) is absolutly critical for the drill guide. The Y allignment doesn't really matter.
Update 3. New version of the Combined Drill plate now uploaded. The old one was apperently too close together.
Update 4: It turns out the motor mount metal plate from the Taz 3 is 4mm different than the one in the Taz 4/5 in important areas. This means the back reinforcing plate will not fit a 4/5 yet. A 4/5 specific variant will be uploaded tonight. In my defense I don't have a Taz 4 or 5 Chassis to test the plate on hehe.
Update 5: Version E of the 4/5 motor endplate, the holes are right now I think.
Note: This will fit a Taz 6.
Update 6: The new idler front plate has a small recess to accomodate the new Y axis belt tensioner tension bolt http://www.thingiverse.com/thing:1656341 It is otherwise unchanged from the 1.0_a revision.
Update 7: The Taz 6 bed plate has 4mm wider spacing on the stock bearing mount holes. There is now an uploaded drilling guide that takes that into account.
Update 8: The long awaited instructions document is now uploaded!
Update 9, uploaded an updated Taz 6 specific endplate.
