Ormerod 2 Direct Drive Z axis

The Ormerod threaded rod for the z-axis always seemed a bit problematic so I decided to upgrade it for a lead screw. To avoid using a shaft connector where space is tight, I decided to use a lead screw integral to the motor and bought this one from Oooznest.

Initially I went with the standard brass nut but was not happy with it so changed it out for the delrin anti-backlash block.
