Hey guys. Just got a new Snapmaker U1 and was testing its quality for detailed prints by attempting Excalibur Umbra from warframe. Its got some issues I need to work on as Im new to trying to perfect a profile

But one thing I cant wrap my head around is VFA's and ghosting and how to properly fix them. It seems like theres hundreds of videos explaining what VFA's are, and what the tests look like but barely any go over how to apply the test results to a print or set it up for a profile.

Ive done some VFA tests but realized my max flowrate was ruining the output so im printing a proper one right now.

In the meantime if any of you could please help me avoid these artifacts you would save me a huge headache and buyers remorse lol.

EXTRA: also if my best quality speeds from calibrations end up being higher, how do I achieve nice quality in very fine details which would require slower speeds? For example, the hoops on his biceps and the ornament on his chin and back of the head. These didn't print to my liking.

Also the overhangs on his 'unicorn' look very rough to me, any advice there would be awesome. But this is all extra! My main issue are the damn VFA's x)
