I have a Prusa iV3 and I'm using 3mm PLA from Maker Farm that I got when I purchased the printer. In the last 6 weeks or so the filament has broken, about 10" or so from the extruder. Each time it has broken it was when the printer was not printing. I'm glad it didn't break when it was printing because it'd be a waste of time and material.
Anyway, has anyone experienced this?
BTW, the printer is in my basement, I'm guessing temps down there are about 65 or so.
