Unwanted lines (spill)

When the hot end moves about I get a lot of spill between holes and such. How can I get rid of this ?

The nozzle is oozing while moving. The default settings doesn’t do any retraction while inside the external boundaries. It doesn’t really matter as the small strips are covered by the next layer.
To limit this you can change the retract parameters to 3 mm retraction and 150 mm/s speed.
