I am having a multi day problem printing a part. At about the same place each time, the filament is jamming. I have included pictures of the part (partial completion) and the filament. It is clear to me that the filament is going into the extruder either too fast, or is heating up and bending.

I have disassembled the .4 hex head and cleaned. I have readjusted everything, multiple times. I have adjusted the stepper motor voltage and it is dead on recommendation.

This showed up as I got into the last 25% of Ultimachine black filament. The filament up to that point worked well.

I have slowed the feed rate as low as 93%. I am now at a standstill and am at a loss as to what to do from here. Any help is appreciated.
