    Hi all,

    I have designed and build a 1500mm x 1000mm laser cutter build.
    I'm resonably happy with it but ive got a few issues with backlash and belt tension and i'd like to change a few things.

    Im looking to redesign it to try and rectify a few issues to make a nicer build overall.

    The Original build was using 40x40 vslot for the main frame/gantry.
    I mounted chinese hiwin linear rails and used nema 17s, belt drive.
    I had a 8mm rod at the rear of the machine with a pulley on either end connected to a nema 17
    to move either side of the Y-axis.

    I do like the chinese hiwin linear rails, very fast and smooth. And belt drive seems the norm.

    I'd like some opinions on the ideal motion setup for a large laser cutter.

    The new build will be approx 1500x900, similar size to the original.

    If you need any more info about the build, ask away

    Attached a pic of the beginnings of the new build. Just messing around with sizes, frame design etc.
