Tom,

I have cnc'd a unimat SL (older but about the same size as a 3) which I
use mainly for wax with StlWork. The major difficulties were the quill and
the slop in the lead screw nuts. (Backlash was too kind a description) I
added self adjusting nuts for the X and Y lead screws and a worm gear for
the Z with gravity compensation. There is a picture of it in the
[CAD_CAM_EDM_DRO] photo area. Steppers are ~60 ounce-inch surplus 23's.
Within it's size limitations it works well. Free advice available if you
don't laugh too much ;-)
