Rotating Ballnut - design ideas

[Ale]

Hello!
I would like to get some input.
I have finished my build with rotating ball nut. Screws are 3m (y axis) and 1.7m (x axis) long, 32mm pitch, 32mm dia.
However, I do get some wobble when nut is rotating, I don't know is this something I should worry about. I did everything as flush and concentric as I could. Screws are tightened on ends, not too much tho.
Below are videos. Wobble is about 1-2mm.

It's just a matter of fine adjustment of the alignment of the screw and the ball-nut and the rotating nut assembly.

Unless you machined the rotating nut shaft so it locates with the ball-nut body then it's very easy for the concentricity to be out a little bit so you will need to align them carefully. You are very close so a little adjustment here and there is all it will take to get it right.
