Prusament PETG not sticking to a large bridge.

Hi there!
I am designing a enclosure for a small pcb, It works very well in pla and extrudr petg, but for some reason i can not get a new layer to stick to the somewhat large bridge. The bridge itself comes out ok but any layers that come after it rather blob on the nozzle rather than clinging to the bridge. Ive tried cooling down the nozzle a bit, reducing speed, different layer heights. On the left is the same part printed in extrudr petg at 225°c, it comes out very nice. The right one is at 230°c and .15 layers. its the best one ive got so far.

Post the file you are printing as a 3MF file zipped and I am sure someone can help you.

Same error.  I did open it in S3D and it appears to be ok.  I will try to print it.
