Strange extensions

[remyhx 0]

Hi,

 

i’m new at 3D printing; this is my third print 🙈. 
 

i noticed some strange pits and extensions, while printing in fine 0,1mm with some adjustments to speed (max 35) acceleration (max 2000), print jerk (25) and outer before inner walls (these changes were made because of some suggestions in a YT movie, to print more precise)

 

printer S3, tough pla and pva. 
 

And maybe its just normal, because of the circumstances (next to openings which are supported by pva)
