    Re: ball screw nut replacement

    Going from memory here, X-axis had something like 0.007 backlash, Y and Z were around 0.002 or less.
    I will double check the values this evening for X axis.

    Re: 5000 rpm option on FL300-II

    Looks very similar to the ones sold by Smithy, probably another Z-Mat made lathe?
    I think with the turret the pricing is very close.
