Thanks Mike, I was reading the same thing. These are part of the Fusion kit and the backlash is excessive, there is at least half a turn of the lead screw before the nut catches. The other two axis have no backlash that I can feel, haven't bothered to test them yet. I have a feeling the nut is missing the majority of its balls? I haven't removed it to check so that's just an uneducated guess. Good thing I have so many projects on the go having to wait on one is not an issue. Working on getting my little Unimat lathe hooked up to the sewing machine motor I bought over a year ago.
