    Robert,

    I am starting to build my OX virtually in sketchup to be sure I have every thing I need and reduce the number of surprises during my build.

    Can you update the resource file with the items in your latest kits? Mainly the Z Axis plates are missing.

    Thanks again for the hardware, it looks great.

    I am :)
    Ty on a positive my parts arrived for the completion of my OX, I will just hide in my workshop with the smell of fresh v-slot being cut to size and some test parts fizzing away in the anodizing test rigs

    Sometimes my hobby is the only escape

    It is the gratitude like this that makes it worth while and so easily shared on my part :)
    Also making great friends and interacting with like minded individuals has contributed to my projects succeeding ;)
    Special thanks must go out to @dddman as your help has touched my little angles heart and she cant wait to start printing on the i3 :thumbsup:

    I hope she likes her frog! I'm pretty sure she will print the whole family! I'll have to make the 7 hour ride someday to meet you @Robert Hummel . 700km and the language barrier didn't stop us! We will have a frog army! Or maybe an i3 army!

    Well I got the E3Dv6 installed on the i3 and finished packing up the OX AI kit :)
    The kit is up for grabs as I have caught up on all of my outstanding orders, first come, first serve ;)
    Here's a pic of the hotend

    Robert,
    i3 printer looks nice.
    Which model is that extruder? Could you provide a link?
    is it a lead screw on the z axis?

    dddman,
    E3D V6 is the hotend, not the extruder.
    I ask for the green plastic parts in the picture, the part that pushes the filament into the hotend, do you know where to get the stl files?
    Also if there're lead screws in the z axis, do you know the part name or the link for the part that holds the leadscrew nut and is kept in place using the vertical linear shaft?
    I'm improving my i3 and I really liked the idea of using lead screw for the z axis, I think it could stop z-ribbing in my prints.

    See if any of you guys might be able to give me some input. I have an OX running a hobby CNC board and im having difficulties running slower feed rates but none at all during higher here are my motor tuning in Mach3. All steppers are having same problem and same setup. Also I did check my grounds like Robert suggested all look good. Only motor thats not doing this is my Nema17 on the z axis. Any help would be greatly appreciated.

    Velocity 1000
    Acceleration 200
    G's 0.020395. . . . .
    step Pulse 5
    Dir Pulse 5

    Also i am running 1/8 micro stepping on an older computer i see this the worst when changing directions or making a slow diagonal cut. Could this be to much processing for my computer

    Very nice job on your Ox. I am wanting to build my own Ox. I am pretty new to the CNC world but am wanting to learn. I think an Ox would be a great first build. Wondering how much for your parts shipped to Utah. Please email me when you can [email protected] thanks for your time.

    On the Nema 17 motor for the Z axis, what is the purpose for putting so many spacers on it? Is it better to be up higher?

    Most of the time when you see spacers or risers on a motor mount for a lead screw driven axis Like the Z axis. They are there to allow clearance for the motor / rod Coupler. Like this sketchup example. If the Motor was to be mounted directly to the plate without spacers you effectively lose travel distance by the space that would be taken up with the coupler.

    I'm looking to order some V-slot. I was trying to figure out what sizes I need to order. Do you have any good pictures of the base?
    I'm going to make mine 40"x 30" (1000mm x 750mm) and just need to figure out how much of each sizes I'll need. If you could post a few pics of the base that would be awesome. Thank you

    Hi Robert, I have been trying to get templates for the plates which I can print on my inkjet print, then hand cut the plate from aluminum scaps that I buy from Lifetimer Boats for $2.50cdn / pound. Everything I download from OB will not print at actual size and will not give me dimension so I could hand draw my own. What would you charge for some actual size templates. Also how much are your plates delivered to Cowichan Bay, BC, V0R 1N1?

    Try this:
    http://help.sketchup.com/en/article/114462

    I select "parallel projection" and then "top" from the "standard views" menu

    Also see the dimensioning tool from the "large tool set" available on the "view" > "tool palettes" menu. http://help.sketchup.com/en/article/94982

    I've used it successfully to make some parts by hand see http://imgur.com/a/CbSmt

    Thx Kerry, I tried it and it works but not very good, unless I missed something. I got another suggestion from Kyo that I will try.
