Welcome to the group. You will find a wide variety of members here
with everything from newby status to many years in CNC.

The magic triad is: CAD->CAM->Control. For CAD you can use anything
from the (near) free stuff to the expensive.

For CAM you have lots of choices too. I still consider LazyCAM to be
in development and in Beta. For something that is a little more
mature, take a look at SheetCAM (www.SheetCAM.com). Does 2D and 2.5D
routing, milling and shape cutting with a simple user interface and
powerful features. It won't crash your budget.

The winner hands down on any Windows based controller is MACH3. Over
9000 users and a very active forum for support. Questions get
answered quickly.

The hardware side can make your head spin but several names always pop
up for drives and other components.

Ask questions and remember the old saying about "opinions" (:-)
