Lead screw compensation

Does anyone know if CNCpro or other inexpensive parallel port G-code
interpreters offer compensation to make the rolled thread ball screws work
as accurately as the ground thread screws? It has been suggested to me
that I would need a laser interferometer to do the compensation but, if I'm
only looking to correct to 0.001", I should think that a center drill
making holes every 1/2 inch or so could produce a reference plate that I
could then use with a surface plate and a height gage to create my
correction table.

Please excuse me if this has been discussed at length before. I am new on
the list.
