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?
First, dry your filament, that is almost certainly the main source of the problem. Second, increase your travel speed by a factor of 5.
