Extruding Problem

[Kelador]

Soooooooooooooo I have narrowed it down to a faulty nozzle. How I don't know as it looks clean as a whistle. I swapped the nozzles over, low and behold swapped the issue over with it.

QIDI's Excellent customer service are sending 2 new nozzles.

The issue i now have if anyone can help. On the left nozzle I have printed 10 things 2 PLA in QIDI FILAMENT and 8 in ABS of 4 USE 3D filament.
Of the 2 PLA 1 failed and 1 had an odd discrepancy part way through
Of the ABS 3 are perfect but since the clicking 5 have stopped part way through. Same settings on heat and bed as the 3 perfect ones

Could it be a filament quality issue or a fan cooling issue. I have a piece that i printed 3 times, twice stopped in same place the third time i upped the temp and it printed a bit more but after where it had stopped previous but consistency was different and then still stopped
