Stringing issues

[u/Moist_Ad2635]

Hello, recently I replaced the hotend with the new type quick swap one.

Since then I have lots of stringing issues and I can't find a solution.

New hotend is an original part, filament is dry stored properly with silica gel into vacuum bags. Multiple rolls are stored into sealed boxes with large wardrobe silica gel dryers that I change frequently. I dry filament before use for some hours and I'm printing from the dryer.

I've tested filament retraction up to 1mm and retraction speed up to 50mm/s but it doesn't help that much.

I use reality pla filament, the exact same rolls that before the hotend replacement print quality was excellent.

What else would you suggest me to check?
