I just checked my old z-rod and it looks worse than the one pictured above. Dramatic improvements since the M5 switch, needless to say.
I wonder how widespread this is. I'm just going to throw this out there, maybe it would help to fix some issues, or narrow some down; I ordered my S2 in August and it arrived in December. The serial is #02118.

I know they like everything to be made/assembled in USA, but my lead screw is really nice, and cost me $27 shipped to my door, for 1, from here: http://www.aliexpress.com/snapshot/212901447.html

I would of thought, with a bulk order the costs would be similar to getting some guy in NY to cut and drill some threaded rod.

180mm is it enought ? can you put a picture of your installed screw ? how do you joinded it to the motor ?
thanks

I also think SD should rethink how they are having those rods bored because hand drilling them is just not the way to do it.

Interesting on examining the bore hole at the end of my rod... To say its off-center is a tad of an understatement wink

Major diameter on 5/16" should be 7.9375 mm's .
The bore hole measures exactly 5 mm's.
This means a centered bore should measure 1.4687 wall thickness when measured across its center.

Instead, mine measures 1.29 and 1.64.. putting it nearly ~ .17 mm's off-center ... Or nearly 15%! yikes

Whats ~15% errors in wobble tolerances between friends when you're talking about .1mm layers wink
