Z bracket seems to be loose???

Any input as to why the thread screw wabbles in the anti back lash....its leaving obvious marks on the cuts that its pulling hard and wobbling as it cuts. I've taken it apart several times and reaseemebled it but the same results. It almosy looks like some thre thred is gone on the anti back lash. Thanks!

When my Z axis was slipping I needed to tighten all the concentric nuts to firm up the play of the V-wheels on the 2020 extrusion.
Can you slide the screw in the anti-backlash nut? What happens if you tighten the set screw in the anti-backlash nut a little bit?

I have tighten then and they are as tight as can be. I took it apart and going to reassemble it this morning to see what happens. The whole threaded screw seems to move back and forth but not the anti back lash nut block. It wouldn't let me post a video.
