Retraction is fine but there is some banding o z axis in upper part. Will have to fix that
Stringing Test / Temp Tower
Very quickly slapped together Stringing Test. Markings 1cm apart so you can post-process z-height changes. Deliberatly…

In my case the major difference came from drying the filament :D
But the model is perfect for methodical fine-tuning of other parameters - white filament prefers temp closer to 190, while gray was perfectly fine with 205-210. Thank you for sharing.
wow I never had really any result from drying my filament. That is a sick difference!
@DJGummikuh Yeah, I was shocked myself. Until now I ignored the idea of filament drying. Lately I struggled with heavy stringing. And since it happened uniformly across multiple spools of filament, I thought there was something wrong with my printer/nozzle/heatbreak (choose your favorite :D ). In the end, keeping PLA out in the open can do that :D I didn't have any failed prints, but stringing was happening for all spools kept in the open and went away after drying the filament. So now I'm hopping on the drybox wagon :D

@DJGummikuh It's a direct drive Prusa MK3S+.
@PetrSury huh then still it might make sense to try reducing retraction speed. This allows the nozzle more time to shed pressure while still on the part and should reduce stringing.
Does the job nicely, perhaps a bit thick and tall for just testing stringing.
Edit: As this is a temptower, retract and stringing test I take back my critique :) (edited)

@FilamentFresser In all honesty I never understood why this model is my most popular model by orders of magnitude xD which list did you take it from?
@DJGummikuh I think I searched for "Stringing Test" and filtered by "most popular"

@DJGummikuh I don't know how it happened because I only have your model in my downloads. But you're right it's not your model I apologize for the complications and delete.
@VitekDev_354026 didn't have to, I love myself a bit of confusion everywhere :-)
Still interesting because that model obviously has a slightly different focus, with pentagram base suggesting looking for seam placement and round-about carve-outs for overhang stresstesting
@churroman_776221 then the model named stringing test served its purpose ;-)
@SR25_440940 This looks like a minimally TOO high retraction, with what I assume is the entrypoint of a new print line not starting early enough, leaving you with that kinda ugly right wall.
