Extruder clicking/going backwards

only happens when attached to the extruder but the motor on its own does the same movement.
as deckingman said. the backwards movement is exactly how Pressure advance works.
check the grub screws inside of the bmg. they can become loose as well.
Checked them both, they are all ok.
I managed to print a full benchy with the base values i started with, without pressure advance, and im getting mixed results.
When it prints slowly i get very nice finish but there there are parts that i get underextrusion and over extrusion. Its really weird.

M204 P6000
Your print accelerations are really aggressive. Try M204 P1000
What slicer are you using?

Prusa Slicer, and i would prefer still keeping using it as i have an Mk2.5

60mm/s.
i had problems when i went above 40mm/s retraction speed.

my problem was the slicer (cura) i had "use adaptive layers" on under experimental setting
