Using the LCD knob to change extrusion multiplier on the fly

[gmay3]

Sniffle, I agree to what your saying in theory but there's more to it than a single diameter measurement like we are doing with our calipers. Filament roundness, air bubbles within the filament, mismatch of automatic correction delay to filament slipping on the hobbed bolt, slight heat change of the hotend, hotend tube friction etc etc.

It's very possible that a input filament measurement system that changes the extrusion dynamically could make the print much worse then without it. It would be awesome if someone was able to do this with good results, I definitely encourage it. I'm just not going to be the one to do it
