Cannot get rid of stringing
I am dealing with an unusal amount of stringing on my Prusa i3 MK3. I have been spending a lot of time on the stringing documentation page. I am getting prints that look like the bad examples there. I am using Prusa Slicer with PLA, and I tried using default settings, as well as creating my own custom settings based on the recommendations there. I am using brand new hatchbox PLA. Currently I can reduce stringing a little bit by using these additional settings:
Nozzle temperature: 205
Retraction: on
Retraction length: 1.8mm (any higher and it will clog)
Retraction speed: 45mm/s
Layer height: 0.25
Avoid crossing perimeters: On
I also tried doing 185 for nozzle for PLA and nothing changed.
Can anyone recommend anything?

RE: Cannot get rid of stringing
I had a rogue roll of white PLA, that would string like crazy.
I lowered the nozzle temperature to 170C where the Low temperature extrusion setting kicked in, and prevented extrusion, so I reset the Low temperature extrusion limit setting to 140C, (In case I needed to print lower than 170C, and the prints improved.
In the image above you can see that I was still suffering with stringing when I printed that model using Mosaic Palette2S Pro.
the black is TPU, used as a hinge.

RE: Cannot get rid of stringing
The prints got better once I increased the Low temperature extrusion limit setting from the default 140C to 170C, where the Low temperature extrusion setting kicked in and prevented extrusion.
