I really did not find a good discussion on the topic, so I thought it would be a good one to start.

The way I level my platen is the same way I level my 3d print bed. I have a bunch of 3mm drill bits I tape to the platen in 3 spots and then I manually move my print head over the drill bit. Not the actual print head, the plastic part that hangs down along side of it, and adjust the platen until it just about touches.
