Re: Extruder feed wheel jumping backward

okay, here again. Should be sleeping but you know how it is!
Light bulb moment I think.The part shown in my previous post is a spiral and when I played the slicer through the layers i found that in the initial layers the nozzle would travel from the spiral centre to the outer wall at the end of the spiral staying within the path of the spiral. This took some time.
So my theory is that the filament wasn't primed when it reached the start of extruding. this explains the gaps hown in the photo to the right of the boss.
Similarly, half way up the bore of the boss the inner walls fail. This also shows a change of print pattern. if you look closely you'll see thatfailure of print in the bore starts where the failure of print on the outer wall starts. In the slicer when i play the movement through the nozzle moves from the centre of the spiral to the inner wall of the boss. Again this is a long movement where the travel follows the path of the spiral whilst the filament is retracted.
My problem now is what settings to change to overcome this.
Any ideas guys and gals?
thanks for listening to my ramblings, even if no one answers it helps to get my thoughts in line.
