    Default My first DIY machine

    Hi all,

    Newbie CNC'ist here. I've just knocked together my first machine. It's very agricultural, but I consider it a learning experience for the next one

    I think it's way over-engineered, but I figured I'd re-use some parts at a later date on a larger machine... In it's current configuration it can handle jobs up to 200 x 250 x 50.

    The drive screws are 1/4" all-thread with 2 nuts per thread, coupler at one end, and recycled motor bearings at the other.

    Quick BOM:

    Motors, 3x NEMA17, 62 oz-in, $60
    Supported linear rails, $55
    Linear sliding bearings, $90
    Couplers, $12
    Power supply, $40
    Controller board, $47
    Keypad controller, $19
    Misc fasteners, all-thread, MDF etc, $27

    For a grand total of $350.

    I already had the Dremel, so that's not included. I don't have a computer or software yet, but the keypad is fine for playing at the moment.

    I think I should buy you a coffee sometime and pick your brain for an hour or so.
    I want to start one..

    Now fully computer controlled. I'm running LinuxCNC on an old Toshiba laptop. Short video of basic engraving here:
