Being a computer nerd and being interested in machining and metalworking, CNC mills have interested me for quite some time. Ive read the CNC robotics book by Geoff Williams and it has given me some good insight into what goes into making a hobby CNC machine. Im looking to build a small gantry style machine just to little projects I have in my head. I have a couple questions, I didnt see a newbie section but if this is in the wrong place, sorry.
1) Is it possible to cut metals and plastics on a hobby cnc machine? I have a computer case project thats just begging for a CNC machine and most of the stuff I would want to do would be either plastic or metal. Would a router be best suited for this and what sort of cutters would I need?
2) Would the hobbyist kit from stepperworld.com be a good starting point? If I had the schematics Im sure I could build the circuits but $250 for everything doesnt seem bad and it seems it would be a lot more cost effective this way.
Thanks for your help.
