    I bought an 8mm lead screw on amazon and found out the openbuilds lead screws are actually 7.8mm in diameter not 8.0mm. Anyway, the openbuilds part store is out of the 500mm length. Can someone tell me if there is another source for these?

    I was bummed that the 8mm lead screw that I bought wouldn't fit in the bearings or the openbuilds flexible coupling. I'm sure they could be pressed on but that would be a pain...

    Hello Eric,

    You could sand the ends of the screw to get it just under 8mm and fit them in the coupling and bearings.

    I thought about that but the anti-backlash block would be Super tight....

    The anti backlash nut loosens up with use. The Openbuilds parts store used to sell the true 8mm screws and there were enough complaints that now Mark has them specially rolled for a better fit. But yes, the recommendation at the time was to lightly sand the ends and to chuck the screw in a drill and run the nut-blocks up and down a few times to loosen them up.
