Thanks for the help, i appreciate it.
Yes i had the extruder off and cleaned some very very small flakes but nothing much, then put it all back again and no different.
when i load the extruder it pulls the filament in nice and smooth and ive held it back with some pressure and it managed to pull it np unless i really do hold it back then the extruder starts clicking. so im lost to what can be happening. the print im printing is a print ive done 20 or 30 times so its not that.
