Hello all, I just got my first printer, an Ultimaker 2 Extended, and I'm trying to adjust my settings to get the best print quality possible. One problem I've been running into consistently is not being able to remove the brim cleanly. Bending it back and forth until it breaks off always leaves a ragged edge, which would not be a big problem to clean up, except that when I do so the bottom layer of plastic will peel away from the bottom of the model. In this photo, I broke off the piece that peeled up:
Other images of this print, pre- and post-cleanup, are here.
All of the settings I changed are listed below; anything else was left at the default value. Any advice fixing this problem or on improving my print quality in general will be greatly appreciated.
