under extrusion.

getting some under extrusion. this is the klipper PA tower. the under extrusion starts after a corner up to a point, (this point is the actual prefered PA 0.045) . then it starts underextruding after the corners. it seems to be okay at 0.045 but i dont think it should be under extruding before hand....

this under extrusion seems to be only PETG (no matter what brand. confused.) surely its not too wet.. i cant even hear bubbling and its in a heated filament holder.
