12" by 24" is pretty big, I would look for a older full size CNC machine that needs a control retrofit!
Do you sell any of the cut offs cheap?

I wasn't sure where this question should go, but I figured this is the best place; although I'm sure it will be moved. At any rate, I work at a metal distribution place so I have access to cast tooling plate and blanchard ground steel. We can also cut the cast tooling plate with a metlsaw plate saw to +-.002. So the question is does anybody have a parts list that a beginner to CNC mill DIY could follow. I would say my budget it $3000 spanned over a few months. I would like to use the cast tooling aluminum if I can, but if not what is a better choice? The application for the mill would be milling 12"x24" alum. 5052 or 6061, brass C360, and maybe some 1018 or 12L14. I have only a limited understanding as to where to begin, but I gather I need a motor to drive the tool bit, some decent size servos, and some good ballscrews. I also have a computer that I would like to use with Mach 3 if thats a viable option. I just don't know, in this industry, what good name brands are, what tolerances are acceptable, or where to obtain the parts.

Patience and perseverance have a magical effect before which difficulties disappear and obstacles vanish.
what be the benefit of retrofitting a cnc if it's already a cnc? Also would I be able to stay in budget? I think it would just gain me more knowlegde and experience if I built one from scratch. Also I'm sure I could get you a good price for metal, just let me know what you need.
The advantage to buying a old CNC with antiquated controls is PRICE.
There are some great deals out there between $500 to around $2K that already have ballscrews and good servo's
Replacing the junk servo drives is a cake walk and you end up with a very good heavy duty machine for between $3,000 - $4,500 dollars total cost
It would be very difficult and almost impossible for you to build a new CNC machine with 4500 pounds of mass for anywhere near that cost.
Where are you located?

I am in southern California. Where would I find one of these cheap cnc mills? I have looked on craigslist, but only see nice cnc's for $7-$8thousand. Also if I'm just going to buy one, why change anything if it world?

The reason why you upgrade the controls is because they are 25 years old,
antiquated, not compatible with Mach3 or don't work any more.

Now thats an ugly beast. Maybe ill just get a better one.. is something like this worth investing ? http://inlandempire.craigslist.org/tls/1124145266.html thanks.
would this kit be a good pick up to start building? http://cgi.ebay.com/3-AXIS-CNC-Route...3A2%7C294%3A50
Ixenn,
What do you plan on attaching it to?
It might be ok for a small router or a X1 style mini mill.

A X1 type machine wouldn't be bad. I don't mind spending good money to get better components though. Like I said though, I don't know any good brands. I am also trying to figure out how long of a ballscrew i need to buy if i want 12" of travel on X and Y.
hey!
