I Just got my prusa i3 mk2 kit up and running. I’ve been calibrating it all day for PETG and i was finally able to get a perfect print. I thought i was completely set. But it seems that every time i remove a print from the bed, the whole calibration seems off. I had a perfect print, then i printed the same thing again after removing the first print and the z height was way off, i went from a live adjust z of -0.045 to -0.375 to get it to print again.Am i doing something wrong? I thought this auto bed level stuff was good. Currently i am not happy with how flimsy this bed is and how the auto level seemingly isn’t really helping much. Am i supposed to z calibrate after every print? Frustrated. http://ift.tt/2eoc1eW
