Here is a 4 axis cnc control board I bought at a very good price new version 4 Axis Stepper Motor TA8435H driver board - eBay (item 110377733782 end time Jun-14-09 19:20:00 PDT) they're only 58 dollars plus another 20 dollars for shipping. If you have some printers laying around you could scavange up some stepper motors may not be able to run your current mill with steppers out of a printer but could run a dremle on some drawer slides or window slides. Then you could use google sketchup and mark 3 for the free software.
