Doing a lot of tinkering I still cannot get it to print past a certain height.

I printed three pieces - all of which worked perfectly, then figured I had it worked out... printed the tall piece that has been plaguing me for quite some time and boom - failed again.

It is cutting a notch into my filament - could this be heat creep? I have felt my extruder motor and it feels fine, not hot at all.

I'm still just frustrated and lost.
