    Look at that @intp lol

    [YOUTUBE="http://www.youtube.com/watch?v=6drMZqmyXQc"].[/YOUTUBE]

    I found out the most cheapest way to get a good quality mill is the PROXXON MF70 reassembled with 3 steppers and computer interface for 800 Euro.

    But thats still too much and my girlfriend would kill me, so I am gonna build a thing like the macgyver above

    You'll need to be able to program PLC, too, entropie :P
    I helped repair a big CNC machine once. It was pretty hard. In the end, they brought up some parts and a techie from Germany who did all the complicated stuff.
    The whole story, just some box full of wires and relays, cost like 20000.

    Ya, I had that discussion earlier with intp. I dont want to build a 20 k thing, just 3 steppers and a dremel drill glued onto it . That thing just have to help me make some parts out of aluminium so i can build my robots.

    I havent dug deep enough into the electronics yet, but building stepper controls and a control logic with AVR chips I already have for my robots. Soldering a computer card tho, that will be real fun

    It's going to be interesting to see if you can build a CNC machine out of a dremel and glue
    Programming PLC is a piece of cake, though. I have more or less forgot how to do it, but I learned it really quickly back in the day.

    Yap gonna be a challenge that will take some time, I am sure. I have nearly none practical skills in working on metal but from the tutorial above it looks like you only need to drill some holes and I think after the 6th drilling head I'll find out which one is the one for metal .

    But I'll start with the things I know so far and plan the whole thing in CAD, gonna see what happens then .

    lol how do you control that thing with a computer?

    cnc = computerized numerical control

    enyway, imo just make normal non cnc machine like that. just build it so that you can put stoppers in the rails

    Ya those things are generally called a "cheese mill", cause its good for cutting cheese and thats it . There came a board layout with that thing above but it was only a totally basic stepper control.

    Here is a real thing and that's intresting to be rebuilt. I linked parts of the diary the guy made in my personal thread:
