I’ve read in several places that using back off speeds and clean nozzles can help. I’m running with a new nozzle. Travel speed 150, retraction speed of 20, print speed 50. I think some of these are just defaults with cura 5.4 but I get the same thing with a higher retraction speed. What else should I look at?
If you don’t mind slightly longer print times, activate “Avoid crossing perimeters”. It doesn’t fix the stringing on travel, but it tries to put travel moves inside the model. It generally improves print quality by a huge amount.
