Attempted a print - worked perfectly. printed a pair of parts to switch from threaded rods to lead screws. The part that you screw the brass nut into.

With those printed - I found an interesting thing happening.

When I click Auto Home, it does the X and Y no problem. For the Z it acts like it's going to extend the servo arm and doesn't but starts down looking for that z-stop anyways. I manually extend the arm and it finds the level just fine. From there IT pulls the servo arm back in - not far enough yet but it does the work. Very odd?!?!?! Why won't it go both directions?

Also now it's time for me to re-upload a firmware with the new z steps. I gotta go find those numbers again tonight as well.

Any thoughts on getting my servo to work properly?
