Hi anybody advise me as to what is causing this:
I have checked stepper voltage and is correct, printer head is not clogged, I can push filament through by hand,
as you can see the print starts of ok but the it seems to not be able to push the filament trough and once this happens I cannot retract the filament either, it gets stuck in the tube fitting (also in photo), not in the extruder. printing PLA, at 185 degrees, lowered the temperature in case 190 was to hot. Please help I am now completely lost for ideas, thank you. Ted
Sorted, it was head to close to bed, causing a back pressure and so clogged the tube above the print head
