Nevermind this, was wrong again, but you got me in the right direction. Thanks for that^^

Thanks for all the helpful replies.
@o_lampe I would like to stay away from ball screws, as they tend to be rather expensive or a cheap hit/miss. And I'm already very impressed by the results of the belted Z. I did consider other gearing solutions like a worm gear but it is the same pita as acquiring quality ball screws, and a mediocre solution would probably give me more headache than my current counterweights.
I didn't think about the gearing ratio to much, went a little crazy probably should choose less ratio.
How is your ball screw setup geared? belt and pulleys?
I could probably do a 1/10 belted space wise.

@jay_s_uk special thanks for the clarifications

@dc42 I didn't. something like this first I could find on aliexpress? Are they in holding position when no power is applied?
