Fully automated bed leveling

cults3d

I was tired to spend so much time to level my bed every change I made so I've looked around for a way to automate the work. Found few thing that I didn't like too much, so I decided to start from scratch and design my way to do it. The light bulb has switched on when I remembered that foot activated door lock (you know, push pin to lock, push lever to release), simple and effective. Just what I was looking for... I just had to scale it to right measure and add an (optional) 9g servo to automate the lever unlock and some minor Marlin firmware configuration, 'et voilà', no more or less complicated mechanisms, switches, sensors etc. It's a Public Domain project, so if someone will help to improve it I'll be grateful.
