before i start to build my mini router, i've a few questions if any1 can help!

i wanna start 3d milling (faces, badges, etc)in wood but i have no idea on what cad/cam would be best for a complete novice like me

what type of steppers an drivers will be best

would 3" or 4" travel in Z best

an how does the m/c know where its home positions are without limit switches

oh yeh, im on a tight buget!!!

no doubt ill think of a few more later but till then

thanx in advance
