Hello Team!

 

I have a problem with printing overhanging surfaces. Based on the Convex/Concave test, the problem starts at ~50 degrees on the concave side.
At the same time, there are no problems on the convex side.

I tried to change the temperature settings (190-225), I have 100% airflow starting from the 2nd layer.
Changed line width settings (0.4-0.8) at height 0.2, set Arc Welder and Linear Advance, but nothing changes.

Any ideas where to look?

Below are a couple of photos for an example (cuffs and fingers, layers are uneven and sag).
