If you are cooking your filament in the oven it is best to keep under 80 C and cook longer if needed. IF YOU DO NOT you will not be able to leave your printer unattended as the filament will be sticking together on the spool. Maybe its OK for 10 min or 30 min but then it will not un-spool and the stepper can skip steppes from being held back by the filament.
The filament can even break off from the spool then you are scrambling to get the end released from the spool and put it back in the jigsaw before the remaining filament runs out.
Kinda strange, I took it out of the sealed package that had descant in it also and i printed crappy from the get go. After checking i saw that it had bubbles right from the start. I think this was an old roll that got sealed up as there was dirt and a long black hair wound in the filament.
Top notch stuff this is!
