Well, i actually have a finished print. Even with the PEI, i can take the model with just two fingers, and barely give it a little tweak ant i pops off easily. i still feel like is way too easy. i used z-offset of -0.05. First layer is reasonable, but there was a couple issues. I had a small blob fall off the nozzle a couple times, and turing a fast non-printing translation, there is some dribble from the nozzle. It dint seem to bother the overall print, however. Any ideas on that?
