Printing here with eSun PLA at 215 C on a Prusa Mini, and there are lots of hairline strings.

What's causing those strings? Temp too low?

You already got a good answer about lowering temp and tuning retraction. Other than that, you have underextrusion there (gaps in the flat part on the build plate). I think you should extend your calibration:

Calibrate temp - flow - retraction

To reduce stringing you want:

  • lower temp
  • higher retraction
  • faster travel speed

Be careful with first two, if you go too far you might get a clog. Sometimes its just better to accept some stringing, but since you are at 215 I bet it can be improved quite easy
