It turned out quite a few decent prints when I first got it, then one failed to stick to the bed, and everything has failed since. I'm printing with ABS because.well, that is what it came with (we bought it third hand). I've had a lot of bed leveling issues, and found out that the community who uses this printer apparently doesn't use the built in calibrator because it's just not very good, but other tricks-I'll give that a shot this afternoon as well.
