Any one out there ever have this happen? Filament wouldn't extrude tried to push by hand with no luck, did a cold pole got nothing out, tried pushing the filament by hand. again, no problem. came out fine. I let it cool down then tried to start a print. no filament came out again so this time I pulled the fitting that holds the PTFE tube to the hot end, I then proceeded to do another cold pole and got this. a bit of a corkscrew but it was a good cold pole it even has the micro tip from the nozzle
