Necrofiliac I see.
After over 6 years of printing mostly ABS I know how it smells, how it feels, how it looks, how it breaks, and how it reacts to acetone etc.
Keep conclusions to yourself. If you knew 10% of what's wrong with the printer (eg. errors on Prusas side) you wouldn't be surprised if yours was PLA (and I don't really care if JP wrote it's from gold). I consider myself one of the lucky ones as I only had to replace steel rods, bearings, and the filament sensor (until now - will see how it goes).
