Simplify 3D Profile feedback (PLEASE HELP)

I'm getting a ton of underextrusion around curves. Also getting TONS of strings... Please help ;)

they gave us default extrusion multiplier of 20 which is ok. I'm happy with 21. Stringing is due to wrong number for the retract. Try 25 - 30 for retract and 8000 for speed. Works great for me. Good luck!

PS: also make sure your filament thickness is correct. 1.75 is not always 1.75. Measure from 3 different spots then average the numbers to get a final average thickness. Mine is usually1.72 and putting 1.75 will give me underextrusion.
