I am replacing my Z nut with the updated adjustable nut.
I have the nut but not sure how to face the nut when I install it. Adjustment screws on the nut face to the RT or to the Left when looking from the front of the mill.
Next problem I am replacing the lead screw bearings on the z axis one was ruff.
is this
WhenI I took the bearings out a spacer was in-between the bearings an original design or added by a previous owner??
