I'm looking for some advice. I'm as green as they come but I am going to get there. My main goal is to be able to do 3d wood work with a cnc. I'm in the process of looking for a cnc machine 4x8. I'd like to be able to use Artcam with it. I'll be straight out honest. I might sound a little silly with my questions. I keep hearing of this Mach 3 program. Do I need that first than Artcam? Is there specific things I should be looking for on a high precision cnc machine (what specs)? Can any one point me in a good direction for reading. Are there certain books I should shove my nose in first? I ask all these questions because when I research them it feels like I'm going in a circle with no clear answers. If anyone can give me even a whisker of advice I'd appreciate it so much. I'm eager to learn
