Rare Extrusion problems in determinated layers

[abelquiles76]

Hello , I want to show you a rare problem and I’m going to try to explain it.
I print PLA with 0,2 and 0,4 nozzle. Both have the same problems.
Always when the piece has a change in their geometry, the layer seems like a extrusion problems, and of course, the piece is extremely fragile in these point and broke finaly.

if you can see, the problems start when another wall is finished.
Anyone can help me or tell me some ideas?

Tests 205 to 215
Flow - 0,96 to 1
Unchecked " slot speed in overhangs"
Multiples speed options…

thanks!!
