    15000? or 1500?
    no custom parts needed just cut the rails to the length you need. stock 1000x1500mm v-rail setups give about 820x1270mm cutting area.
    Just don't get the Kit and get the plate set you want with the V-rails.
    Or
    got to Ooznest and get the kit any size you want

    Hi,

    I am afraid for the C-Beam the biggest would be 1000x1000mm, screws whip if you go any longer

    Oh Right I read C-beam and think Ox LOL.. for that big Dual-belt Ox is really the only reasonable way, without going to 12mm screws or rack and pinion $$

    P.S. I hope the steel works okay and is solid enough with the nema34? and aluminmum sides?

    Weight isn't the issue, the nema34 size is much bigger and will not fit on the standard ox plates which are all made for nema23.
    nema23 makes plenty of torque for an ox, enough to do damage when it crashes.
    More torque isn't always better, you reach a point where other things are limiting performance, such as overall stiffness, and the drive system (such as belts or acme screws).
    these are what i'm using and i have not wanted for more power.
    nema23 269ozinch
    Which package deal did you get? the one in the pic? then you want nema23

    When the boards and Nemas come im going to explore with them, test them etc, i will take your advice and most likely sell the34 and get the 23

    OX CNC Full Kit | Everything For A Hobby CNC Machine

    i got the other bits of ebay
    EXTRA Z CLEARANCE OX CNC ROUTER GANTRY PLATE 28 V SLOT XTREM WHEEL 13 ECCENTRIC

    The frame is what i really need the Black one 1500 x 1000 i think it is
