The Z axis motor will supply the up/down motion of 8 or 9 inches to slide the rod against the dials probe finger. The post I have to assume, and according the the QC sheet that came with it, is within .0002" of square to the bed. It is not adjustable and has not been removed from the bed on my watch. My reply is late, I had gone back to bed to catch a few while it rained and a few turned into 4 hours. :) And its not quite done yet.
