I have a problem with lots of stringing on the right nozzle.
I’ve done a bunch of calibration to find good temp and retraction settings. Print results are good on the right nozzle when the left nozzle isn’t used. However, when running a dual mode print I always get a huge number of super thin strings from the right nozzle. This happens with both Luban and Cura with several different filaments.
I’m starting to think there is a firmware bug that stops retraction in this mode or something like that. But I haven’t seen a lot of reports of this, so a bug seems unlikely. Has anyone else faced this and found a solution?
