I'll start this off by saying I know absolutely nothing about CNC routers other than the basic idea that they follow a prescribed tool path created by a computer to create 2d and 3d shapes.
That being said, I recognize the potential of these machines and am very interested in learning about them but I'm having difficulty knowing where to start. I am computer literate and have used AutoCad a little but I am far from proficient in any drawing program. Is there a "CNC Routers for Dummies" type book that is good enough to get me going, or do I need to actually go to training somewhere?
Also, as far as the equipment is concerned, I'm a little apprehensive about buying a used machine because at this point I wouldn't know how to troubleshoot or fix any problems with it, but I can get a lot more for my money than buying new.
I guess I'm looking for some advice. How did you learn to work these machines and is there anything to help speed up the process. What type machine would you get, what software, etc. as well as what to avoid.
