I have been working on a new low cost CNC conversion of a Dremel Drill 
Press to CNC. Essentially, it is a 10X10 ball slides spot welded in an 
X-Y configuration. This is bolted to a tool stand and nema 17 stepper 
motors are connected to the X-Y axis via low cost roll cut leadscrews. 
The Dremel drill press  stand is bolted to a 10X10 aluminum plate that 
is screwed to the X-Y cross slides. The Quill is raised and lowered by a 
stepper motor mounted on a support bracket. The stepper motor drives the 
quill with a timing belt and timing  pulley arrangement. Using the three 
axis controller and a low cost software package I demonstrated at the 
Seattle Robotic Society  meeting  the machine drill 104 holes in under 4 
minutes. Yes this is not for heavy duty use but is great for drilling 
printed circuyit boards and other fine drilling applications. The Power 
head may be removed and a plotting pen inserted. The unit can be seen in 
my web page at

Let me know what you think.
