I think it's the filament I'm afraid to say. PLA absorbs moisture rediculously fast, there is a slight fat section that won't go down the extruder pipe and gets blocked at the top, while the hobbed gear just keeps pulling away at it. See how you have that long stretched section? your PLA was a bit gooey and there was a bubble in it it got caught and the rest kept getting pulled down until it lost extrusion and stops spitting out plastic.
The fact it's pulling it tells me that the problem is on the top end, not the bottom end. If it was some old ABS stuck in there, you would just get a grind out and the filament would get blocked and you hear "click click click click" from the stepper motor. In this case, its not a problem of going into the pipe, it's a problem of a bulge in your PLA that won't go down the very first hole it needs to go into, the holy just above the hobbed gear.Last edited by Geoff; 06-03-2016 at 08:37 PM.
