    The RPM is way to high you want about 10,000 rpm
    Next the alexi bits not right for the job and the inventambles are for acrylic

    The last bit on the page is what your looking for at a fair price for quality

    One other thing I can think of would be the endmill is to far out side the chuck.
    Only the cutting surface and 1/6 " of the shank should stick out of the chuck

    Robert, Where are you getting the fober board? That looks nice. Is it easier to mill than the aluminum?

    I got it from a local electrical shop that was throwing out a bunch of old switch gear.
    It is super easy to mill but hard on the bits
    Got the Z done just need a 10" length of open builds lead screw to finish :)

    Hello Robert,

    I like the work and add-ons you made since the original design. I am sure by now you have a pretty good idea what is involved in milling these, so I'd like to know if you are still considering milling kits for people.

    I have 0 experience in CNC, but I designed and built my own 3D printer, so I am not that far off. The printer I made, I had the alu waterjet. While it worked, the inherent bevel made while cutting made me work more than I had anticipated adjusting the parts

    http://www.thingiverse.com/jayftee/designs

    That is why I am looking at CNCs.

    Let me know.

    Thank you

    Jeff

    I'm currently working on some sets.
    The best bet is to keep an eye out for when they are done.
    I now only do them in batches because I'm so busy and don't like taking orders due to the pressure.
    Some times it's a day or two or a week for kits.
    I take my time to ensure people are happy with what they receive.

    Hi Jeff
    After looking at some of the stuff you made with your 3D Printer, and I know as much about 3D printing as you do about CNC at the moment, I think you're going to be over the moon with a CNC of your own.
    I reckon you will be making some cool stuff in the near future. It's definitely the way to go. :thumbsup:
    Almost like a Definitive set! If you have one, you need the other.

    THEY ARE SYNERGY!! :cool:


    Print yourself a Wagon, and jump on! :D

    Cheers
    Gray

    Indeed, the coined phrase: hog heaven, comes to mind.

    The fact is, i have a design for a cnc machine i made with igus w rails, but i am unsure about the z axis, so i am looking at something already tested.

    Since many parts of my 3D printer came from here, i was aware of the ox, but i was waiting to see if Mark would capitalize and start selling kits.

    So here i am, on a waiting list :)

    Nice work Robert ( don't forget to use screened / shielded cable for connecting the switches ;) )

    Robert, I'm gonna follow your lead and build an OX AI... so at the moment I've got a couple of questions before I head out and have the plates knocked out at a local CNC shop. What thickness is the aluminum for the Belt End Clips? Do you have the drawings available for the Motor/Leadscrew assembly...and would that be out of 1/4" stock as well...

    Thanks in advance...

    So, the Y axis member consists of 1- 20x80 v-slot and 1-20x40 v-slot rail...If that's what I see in your photos....

    No, to make the Y axis frame/rail
    2x20x80 for sides
    Front and back are made with 2x20x40 each side
    In total
    2x20x80
    4x20x40

    Any chance on getting a kit and maybe a few of those limit switch holders?? Very nice work, I need to build a second machine to keep up with my growing sign business and a 2x4 ft Ox would would perfectly. Just PM me with a price and availability when you can. Shipping to N-Fl 32038.

    Thanks,

    Gerald

    Things are crazy but kits are in the works

    Read above :rolleyes:

    I'm sorry for the hold up guys but life has thrown some bumps in the road.
    Kits are in the works and my OX AI should speed things up as it's almost done ;)

    The plates on the top right look like multicopter arms? Sorry. I'm drifting off topic :)

    Wow, awesome stuff, this is the sort of thing that caused me to find myself here. Robert, I've sent you a message (Conversation?) about you know what, lol.

    Robert,

    Is the content of the files you uploaded in the file section, up to date compared to what you are milling?

    I'll print them and see how it goes. I definitively want alu plates, but in the mean time, I have to learn what I can about CNC, so I might as well start now... :p

    Thank you

    Jeff

    Hello Robert.

    First let me congratulate you on the awesome work :)
    I've been reading a lot builds lately, since I'm trying to build a CNC router myself, and this seems to be an excellent choice.
    I do have some questions that maybe you could answer me, since I can't seem to find them anywhere.
    What precision can you get with this type of build? I mean using the Belt and Pinion System rather than Lead Screw for example.
    Other question is how do you get your raw material fixed to the work table? I've seen that you don't use tabs on the programming, and from the videos and photos I can't figure how you do it.
    I'm extremely inclined to ordering, but I'm afraid I'll have problems with customs here in Portugal, since it's shipping from outside of Europe, and I'll probably have to pay a lot of additional taxes :(

    Best regards,
    Joao

    If you were to order from the distributor in Portugal, you would not have to worry about the taxes.

    For other European distributors http://openbuildspartstore.com/openbuilds-distributors/

    Hello Rick.

    I did check it out, actually I did check all the European stores.
    The Portuguese one doesn't have more than half the material I need, but I'll try to check more thoroughly and see if I can get a complete list from all the European stores together :)
    Thanks.

    Best regards,
    Joao
