Finally! I have been waiting for this. My Z height has long been messed up. Im also having trouble with my Gazoon Height. I've tried to not think about it as I am very sensitive. Sometimes when I sneeze, selfish careless ego maniacs dash me to the ground and they will say "gazoon Height" and then I know that I still have not achieved either. This video was very helpful as I think all American struggle with adjusting Z height of everything.
