Cura 4.5 wall issue

[Anthrix 19]

Just trying to move from simplify3d to cura and have couple issue. So far all good experience, but one of issues is when after infill starting printing walls inside no retracting happens but nozzle starts moving very fast and blobbing instead of nice print until it slowing down to print same line and finishing nice line. that creates small blobs of filament and that filament sticks to nozzle and get dragged around print.

Second one is if any circle in the middle of the print no retraction happens then it does move from one to another location leaving lines. not so important inside of print but not nice then that happens top or bottom layers.

 

Other wise getting half decent print. 🙂
