as many people have explained to you monkey, almost nothing in this world is free. as my granpa bluntly puts it, "free cheese exists only in mouse traps", thus dont expect everyone to do the work for you, let alone for free, go out and research yourself, and i doubt you will be able to get ready and build a cnc by next summer, sorry to disapoint you,but it aint probably gonan happen, and aside from that, it is seriously expensive, so unless you have a feasible reason i (like asm said) beleive that you should instead consider building a copy carver, itll be good experience, and is still chalenging enough to be somewhat fun
