sean,
i'm slowly (in my very spare sparetime) working up a small (12"x12"x3") low
tolerance cnc machine for light wood and plastics. it is also serving as a
general teach-myself-cnc project. i chose to go with a pre-config'd
electronics / servos package from keling inc. (
http://www.kelinginc.net/ThreeXCNCPackage2.html). after reading lots of
cnczone entries and doing lots of chipset / board / wiring research, i
figured it's 329$ well spent by saving me time, and it's a pretty complete
set of items for a good price. also, this site has some helpful info on
wiring (http://www.robertguyser.com/). i am next building up the machine
using basic 8020 or minitec extrusions and linear accessories. lovejoy
couplings will round out the basic bom. i'll use whatever i have as a cutter
head - dremel, trim router, etc. it should turn out to be a fairly cheap
machine without eating up too much time reinventing the wheel. cam
environment: emc2 packaged with ubuntu. it was a smooth install and the
forums are great. so, i cannot say that this route is flawless and worked
out yet since i'm still in the process, but i can say that i've spent a
bunch of time running cnc machines, spent lots of time reading everything i
could find on the internet and printed about various diy cnc options. i
think this route seems like a pretty efficient and solid starting point.
i'll let you know how it comes out - if i ever get the time to complete it!
have fun regardless of which direction you choose. good luck.
