Adjusting the nut on Z axis rods
How should I measure/adjust them.
Should I measure the height from motor-top to nut, and adjust both the same?
Ran into a issue where my buildplate seems to be tilted, and I'm suspicious it has something to do with the nuts being too high or to low on one side.

What I did in my build was first square up the x-carriage before tightening up all the X-carriage hardware. This was done with a long metal ruler as a straightedge laying from the X-motor plate to the X-idler plate. Details on this is available at the X AXIS ALIGNMENT post in my build thread.
An R/C pitch gauge used as a precision digital level was used to verify this approach gave me an x-carriage aligned with the Y-bed without the heater installed. Now when I want to check for equality between the two Z-rods, I just set the ruler across the two plates and make sure the ruler still sits flat on both ends.
FOLLOWUP COMMENT: Here is my rationale for squaring up the x-carriage early in the build. A total of eight M5 bolts fasten the two horizontal v-rails to the x motor mount plate and the x idler plate. Tightening the eight bolts turns the x-carriage into a very rigid assembly. If the x-carriage is not square when the bolts are tightened, the Z-rods and the X-carriage will be put under strain when trying to straighten it later. IMO, that strain increases the chance of stepping issues with the Z-motors.Last edited by printbus; 12-08-2014 at 11:22 AM. Reason: readability

Or you can just run the head down onto a piece of paper on the bed. turn the two z screws by hand with the printer off until you get even drag when moving the paper at multiple points across the x axis. Or at least on both ends.

I use the 'stick' part of my calipers to measure from the Y extrusions to the X extrusion ( resting the end on the top). I use the lock on them once I measure the first side then make the other side match In theory these should be square...

You can adjust the Z rods to level the X axis with the back end of the Y bed, then move the bed back, and level the front of Y against the nozzle.
