This in theory will only print two layers using a resolution of 0.2mm. You can watch the plastic extrude, and can adjust the bed on the fly. Lumpy lines means the bed is too high. Plastic means the bed is too low. Aim for an even clean extrusion. You will see it...!!!!
Is the wingnut the M3 x 0.5 thread? I'm very interested to do this but haven't found a local store with these tiny wingnuts.

Would there be a benefit to leveling the platform while its hot? Seems this would be more accurate while printing but obviously there is some risk involved.

Do you guys generally see a lot of variation in bed adjustments after printing? I'm assuming this all caused by vibration and heat-cycling of the plastic base that the bed is mounted to?
