 ## Integrated XYZ machines from Urumbu axis components.
 
+###Machine using xy table and a fixed cam-driven z-axis.
+
+This machine is documented [here.](../UrumbotXY/README.md).  It does a nice job of machining PCB traces, but with a few mm of travel, is a specialist.
+
 ### Machine with short z-axis moving on x-beam.
 
-[details](./moving_z_axis/README.md)
+A short z-axis was mounted on the x-beam of the Core-xy table.  The first iteration of this design lacked the stifness needed to machine PCB's and wax.  [Details are here.](./moving_z_axis/README.md) 
 
 ### Machine with short z-axis fixed to the frame.  Moving table.
 
-[details](./fixed_axis/README.md)
+The same axes were rearranged so that the z-axis was fixed relative to the frame, and the xy- carriage supports a moving table.  This arrangement was nearly stiff enough to machine PCBs and wax.  [Details](./fixed_axis/README.md)
