The Omec 750CN Dovetail Machine from Macoser allows you to do any height drawer up to 20.86” and the CNC will calculate the dovetail size to give a flush drawer edge.  It offers pendulum loading for speed, doing up to 60 drawers per hour. Variable travel speed and scoring handle different species or plywood. Ball screw and linear bearings offer minimal maintenance. You control joint tightness, depth, first joint location and how many joints and the CNC does the math.
