Printing defect

[condoevil]

Dear all,
please check the attached picture,
as you can see on the corners there are spare extra material dots. The surface is ok.
It seem that the excess is in the same place where the perimeter finishes. What could be the cause?

Best regards.

Is it doing retractions near those corners? If so, then you probably need to adjust your retraction settings

It looks like your printer may be trying to turn the corner to fast.
Depending on your printer firmware, the firmware can usually be changed to account for this.
If this doesn't work try slowing your print speed down to see if the problem goes away.
