I would not bother with upping the flow rate, that creates other issues.
As a temp fix it was much more efficient to just lower the z-offset by 0.002 or thereabouts.
It is a band aid, but it’s at least its workable for a while.
I also have a 45°dip in addition to dips at some other places, so I guess it something to do with manufacturing and it’s a bad batch.
