Do Not Do This

These are lessons and learnings on what does not work, so that others do not repeat mistakes.

Extruder collision with build platform. I just did a print, walked a way, only to see this after about one hour of unattended printing. I've used the Lulzbot Mini for weeks of print time - this is the first major error. It appears the auto bed leveling did not work, and nozzle crashed into bed, melting it away.
