Makerbot already uses Acme spindles instead of threaded rods.

    Hello,

    My students are finally far enough along in SolidWorks this year that we
    would like to start printing again. Ever since we started using the
    MakerBot, it has had a wobble. We tried the re-alignment of top gears,
    shimming the bottom bearings (as they wiggle around in the bottom slot (not
    a lot, but it is noticeable)), printed anti-wobblers, etc... it still
    wobbles. I think it wobbles more now, then it did when we first started
    printing with it. I have found a lot of sites where the users have
    replaced the threaded rod with ACME theaded rod. I have found these being
    sold on eBay for $75/$85. Do these work? Is it worth the investment?
    This is an awesome tool for my students, and with a little wobble, we were
    able to print some stuff off. But, now that it has a lot of wobble, our
    prints are no where near what they should and probably could be.

    Any suggestions??
     
    Thanks!!
    Bryan
