Would this help?

Hey guys!

Would this anti-backlash nut do any good on our z-axis? https://www.amazon.com/BIQU-Backlash-Elimination-Threaded-Printer/dp/B06XCCDD51/ref=pd_day0_328_5?_encoding=UTF8&pd_rd_i=B06XCCDD51&pd_rd_r=CFNYNYPB3Z3HR56Q4B3W&pd_rd_w=i3np9&pd_rd_wg=EnLmc&psc=1&refRID=CFNYNYPB3Z3HR56Q4B3W

It does not seem to be an issue. The first version used a anti-backlash setup. Tuners out it caused more problems than anything else do to improper use. It turns out, gravity is enough for us without the aid of a spring. That would 100% be needed with any horizontal lead screws though.
