    After 4 years of design changes, and a few prototype parts, construction is under way on Z², a mostly wooden machine with ultra high performance goals.
    For anyone who hasn't seen the design thread, it's here.

    Cutting are will be ~50"x72"x6". Both spindles will have full access to the cutting area.

    All NEW Hiwin linear bearings.
    15" 15mm rails with flanged blocks on the Z axis.
    67" 20mm rails with flanged blocks on the Y axis.

    These have already been purchased.
    X axis will be ±90" rails, either 20mm or 25mm.

    Z axis' will be driven by G251's powering 380oz steppers and 1/2-8 4 start screws from Roton, with modified Roton plastic nuts.
    This may be upgraded to G201x's and the new 400 oz motors from Gecko.

    X and Y axis will be driven with my stepper powered version of Mike Everman's Servobelt
    I built a prototype, but the final versions will be modified slightly for more strength.
    Gecko G201x's powering 570oz motors, geared 4:1. X axis is dual driven with slaved motors.

    Per my usual pace, this will likely take another 2 years to finish.

    Here are a few AutoCAD renderings to get started.
