"My experience is that this depends on the material. With PLA the retraction is less critical as it doesn't ooze to much. There 4mm is enough. With nGen I need more than 5mm to get the retraction to help and reduce stringing. \nFor some materials more than 4mm is just not possible because the material is too soft and grinds in the feeder if you have more than 4mm or the retraction speed to high, Glowfill for example. Then you need to fight oozing with lower temperature and lower speed. \nWhat material did you you use? "
