Tried taking the exclusion multiplier down to 90%. It is a lot better now.. letting it print now..

Took a screenshot of a slightly different infill pattern I did before, and you can see how blobby it is. On the long straights it prints perfectly well, but when the head changes direction it builds up a blob..

Current printing..

8000mm/min , 1500 accel.

At a guess, I'd say acceleration is too low so it's dwelling in that spot and oozing (retraction only kicks in for non-printing moves rather than printing changes of direction).

That sounds better. Your previous settings were almost certainly acceleration limited, although I did I assume the 80,000mm/min was a typo as you'd need a 4 metre printer to get up to speed.

I'd be surprised if you could maintain 8000mm/min consistently, but I think you're on the right track looking for the highest acceleration you can handle, then hunting for the best max speed. It passes the *ear* test, anyway

I thought that. but stupid high or low speeds made no difference at all.

I think I can push higher acceleration. But for small parts its not really relevant.

Finished print

Just as well it had a warning... otherwise I might have had to report that post!
Funny that I'm used to the sight of my own blood but still more affected when I see other people's (and animals etc.) vital fluids...

Looking good, though.

Prusaslicer has a wibby-wobbly all curves fill pattern (I forget the name), may reduce dwell time in any single location?

True. It could end up as a stunt double in a zombie flick
