PA6GF difficult to print

Hi guys I’m trying to print with PA6GF White but I’m having big difficulties. On the pieces I see some protuberances, some growths near the joint line. I’m using the Bambu profile so extrusion temperature 265° and plate at 110°. If I decrease or increase the extrusion temperature things get worse, could it be too little retraction? I’m attaching a photo Thank bye!!!

Another question: where do you find the material profiles? I don’t mean the temperatures etc. but the speed, quality, resistance, support etc.


thank bye
