Hello, looks good! Interesting with the rotating ball nut. I understand it so that you have placed the fixed bearing on the spindle plate and then the other ball screw end is lose. Does it stick up in the air or what does it look like when the Z-axis is fully retracted?

Anyway I have to say that your advice is quite contradicting compared to the advice I have received from others. I am not saying you are wrong but I try to stay open minded!

I did say I was throwing a spanner in the works, I know it's not a conventional way of making this and yes contradicting to what has gone before but it works and works really well it is compact, less weight, and the machine cuts very well, just wanted to give you an idea of what works without going to far.

The screw is bolted tight to bottom of spindle plate (no bearing) and screw goes up with plate, attached is an image when I first put it together.
