Description

This carriage holds the brass nut for a metric threaded rod.  Because space is limited in the normal bearing block area, this puts the mount on the top side of the stepper.  Simply remove the old bearing block from the lower stepper screws and move the two top spacers where the bearing block used to be.  This part is inserted on the top side mounted through the upper stepper screws.  The brass nut is held with one m3 screw & nut.
