Does anybody know what kind of problem these string are?
It’s always while printing PETG.
I use Ender 3 Pro / Cura, retraction and retraction-speed is well checked by stringing tests. But I can’t find out what this could be:
That's just PETG. It's known to be stringier than other materials. What happens is the nozzle dragging around will catch the plastic from the previous layers and pull it into wisps. You would try increasing layer height and reducing flow rate to counter this to a degree.
I calibrated my extruder and found out the right flow rate by the teachingtech website. Now it’s working much better.
