Filament loads fine, then first print fails, filament wispy?
When I load my PLA filament it comes out just fine, but as soon as I pull away the extruded filament, it becomes all wispy, almost like spiderweb. Then the first print I do, whether its just a first layer cailbration or an actual print, the filament stops extruding.
I don't think it's the quality of the PLA as I was using this same PLA earlier this year and it printed just fine.
I've replaced the pfte tube and it takes the filament perfectly.
I've dissassembled the hot end, put a new nozzle on, put a new heatbreak on, ensured that the heatbreak and the nozzle were on tight and touching in the heat block.
The tension springs, as far as I can tell, are at the right setting based on what I've read on line.
When I unload the filament and stick an acupuncture needle up through the nozzle, there isn't any blockage.
Any idea what's causing this?

UPDATE: So after troubleshooting everything I could possibly think of, I tried the most intuitive solution--getting new filament. The problem instantly went away. I suspect my vacuum bags for storing filament weren't air tight and the humidity ruined the PLA I was using. Weird how these sorts of problems always seem to have the simplest solutions....
