When I was at robo and we first implemented the auto level it helped the masses drastically. As long as we shipped with the xz axis fairly straight, people could actually print out of the box. A huge first for us at the time. We were so excited to use it when the code came out it was funny. We all tweaked printers to mess them up and see if it would still print. One of the guys , Jason or Austin, was sticking plastic forks under the bed and getting that thing like 20 degrees off level. It was pretty exciting. The original design was going to use washers as switches I convinced them to do the current end stops. My little contribution.
