I have another question about the blue bed liners. I've tried printing a few things, and I'm having the problem that things stick REALLY hard to the bed. I've ruined one liner and one of the knives used to remove the object. Could I make it stick less if I lower the temperature of the bed from 110 deg C to maybe 90 deg C?

Along with that, I have questions about print speed (what works best?) and,

What to do about printing something that spreads out past the base as it's being printed. While most of the time the printing looks good, when it spreads out sometimes the filament doesn't stick where it belongs. Can I fix this by changing the x- and y-speed? Or changing the z-speed? Or is there a way to set how far the bed moves with each additional layer?
