I’m sorry to be posting this again, but I still don’t know how this works. I looked it up in all the documentation and I still don’t know how to adjust the vertical height.
It might as well be a spin operation, without this.
bah
okay, so from the front view lets say your screw cross section looks like this

[yes, that is a straight line]
the height of your screw depends on the angle rotated, and the height of that piece.
so, if your angle is 360 (all the way around), and your turns 1, the bottom part will be exactly the same height below the start than the height of the original shape [try it, it makes sense, the height is doubled]
so, if you want a particular height, tweak the height of your segment, or the angle value, or the number of turns
