Layer seperating in one area.

Can anyone hep with this please. Its BASF carbon filament at the recommended temperatures but as you can see the layers seem to be separating in one area.

Did you print this with an enclosed front? If not, I could imagine that too much cold ambient airflow would cause this? Or maybe too much cooling fan? I have no experience with this material, but generally high-temp materials need an enclosed front and little or no cooling fan for good layer-adhesion. Otherwise the new layer won't melt into the previous layer.

Yes its a Ultimaker S5,also its a very small closed room thats pretty hot.

Looking more closely (I paused the print) it's just the outside wall in that one area. It's 100% infill and that seems perfect.

Also noticed this but strange it's just the one area.
