All of a sudden my printer has been printing objects with gaps in the perimeter layers. I Switched to a new filament but then I switched back to the old filament (which I know prints well) and the problem was still there! Also a small amount of filament started leaking out of the sides of the thermistor and block. I read that the tubing inside the bowden may need replacing so I have went ahead and done that, but have not printed with it yet.
Filament type: PLA 1.75mm (both new and old)
temp: 190
software: pronterface
slicing: sli3er
hobbed bolt is clean
tension is good
print speed is slow... 20mm/s... slow seems to work best for my printer
print with gaps (ignore stringy support material): [

This is frustrating because it was just working so well. Anything I'm missing?
