Hey Codyp I can’t speak directly to the CR6 but generally a Bowden is around 5-8mm remember this is only one factor play in the tube and speed can also effect stringing. The often over looked nozzle wear as well. I tend to print carbon and flake so brass nozzles wear fast. Really fast, I have by times replaced them every 12 hours of printing. Depending on material printing. All the settings in the world won’t help if the nozzle is oval or worn.
My rule of thumb is if you start getting stringing when you didn’t I change the nozzle first. Then goto settings.
