    Hey all, it's time to put together a CNC router. The one I opted for is the Ox machine from OpenBuilds.

    http://www.openbuilds.com/builds/openbuilds-ox-cnc-machine.341/

    This machine uses nearly all off the shelf parts, with the exception of the 4 gantry plates for the X and Y axes. The DXF files for the plates are provided and can be sent to a local shop for cutting from 1/4" material. I had a local laser cutter cut a set from 1/4" aluminum.

    Here are the gantry plates. I still am going to clean up the edges and smooth out the surfaces with a palm sander:

    I ordered the 3 NEMA 23 stepper motors off ebay. They're monsters with 425 oz of torque and they only draw 2.8A per phase. Also ordered a 24V 14.6A power supply off the bay, and a TinyG controller from Synthetos.

    Here's a quick vid of testing the electronics:



    And a large box of extrusions and various small parts arrived today from OpenBuilds.

    Thanks Marty. It's funny that the box showed up today considering I ordered it last week. Good service so far.

    I admire all you guys that can handle this cnc stuff! To me cnc means "can not connect". I did my time as a radio tv tech starting in 1963. Apart from living in the time of the best music up to then, I also witnessed the first transistors, the first IC's which were in those days were "thickfilms", and the advent of colour tv in the days of discrete component chroma decoders. Colour TV was hard to get your head around but I did manage it quite well, then video tape,etc, and now the disk and God knows what else these days.
    I got out of the domestic electronics when Matsu****a started making flexible pcb's that rolled up into a tube and edge connected into a very small mother board.
    The last 20yrs of my working life was repairing and calibrating audiological equipment and hearing aids.
    Now I make some sawdust and complain about my back!
    So.................................all you guys with the ability to work those newfangled router things with the files and tool paths etc.etc. have my utmost admiration!

    Nice Christmas gift Brian! I will enjoy watching the build.

    Did you get the 20x80 extrusion for the sides rail?

    Welcome to the club! Looking forward to seeing it up and running. Though, the building of a CNC is also an enjoyable experience. (sometimes)

    Those are some good size motors. Should handle pretty much whatever you throw at them.

    Thanks Dave! It's not as complicated as it might seem! With your background I'm sure you could get into the CNC game.

    Yes André, it is the 20x80 for the sides. Hopefully it'll be stiff enough.

    Thanks Robert, I did pay a little extra for upgraded components where I could.

    Went out to the garage tonight and installed the wheels on the Y axis gantry plates. The bottom 3 wheels have eccentric spacers so they can be adjusted to contact the bottom of the extrusion.

    I put them on the V slot to make sure all 4 top wheels make contact with the extrusion.

    Yeah that's correct Herb. I figured it was worth the extra money to get the upgraded wheels. Every little thing contributes to the stiffness and accuracy of the machine after all.

    Uh oh the wheels are turning (no pun intended) :lol:

    I had originally looked online for the plates and saw the ones on eBay as well. It ended up being significantly cheaper for me at least to get them cut locally.
