In my opinion, you should see a nice line of filament coming through and stringing down to the base under gravity, very quickly cooling and setting from the hot end.

If it madly coils under those conditions, I would suspect it is far too hot so as it comes out, it is shocked and coils and clumps.

I'd be very interested to see what the thermos report as your temp to achieve a nice clean line of filament?

I will say again. I am a noob on this so take everything I say with a pinch of salt and my only experience is the e3d hotend which I chose after looking at the designs and been very pleased with. I don't mind being shot down in flames (nicely) but this is the behaviour I would expect.
