just what I was thinking, for cheap pla that's not too bad.

You can try printing slower and using a print area fan.
You an also try different filaments. Some of the better made and more expensive types do make a significant difference in finish quality.

I don't get the printing temperature - is it 200 or 215 ?

Probably one of the best finishes I've sen recently is innofil's new pro 1 filament. Has a really shiny satin finish to parts.
