Missed me? I know you did.   -     As the Ultimaker 3 is now known and will be shipping out towards people and, (don't quote me on this one) hopefully be in the hands of users by FridayNovember. So, I figured I will explain in depth technical details to prevent surprises and improve knowledge for you. I will assume that you are already experienced with certain things from the Ultimaker 2 or Ultimaker Original. I  hope this knowledge will help in understand why things work the way they do,
