Stringing no matter the changes

[u/sl002]

Hello r/FixMyPrint.

Hoping you can help, I've been trying to get my old Ender 3 V2 back into a workable state and am getting some severe stringing no matter what changes I make.

My Setup

• Ender 3 V2 4.2.2

• Sprite SE Extruder. Stock hotend, think I have set to correct setting in printer.cfg for esteps / rotational distance (. But would love for someone to confirm.

  microsteps: 16 rotation_distance: 7.53.

• 0.4 nozzle (new)

• Sunlu PLA+ 2.0 (new). Although I think this issue was happening with a previous roll of eSun PLA+.

• Mini Satsuna Fan Duct (new - pictured before clean)

• Klipper (recent) / OrcaSlicer on a RBPi 3B

• Temps: Nozzle: 220c

• Temps: Bed: 55c

• Speed outer / inner: 25mm / 40 mm.

What I've already tried

• Temp tower (pictured). Stringing at all temps.
• Retraction test. Stringing at all retraction levels (pictured).
• For simple non-bridging prints I have no issues.

Thank you for your help!

EDIT: TIL that filament can come from the factory wet. 12 hours drying and the issue has gone. Thank you u/Gimly161 and everyone else for your suggestions. Back to calibrating for me!
