Retract within perimeter
I am busy printing a container which has five circular holes and a square at the bottom. What I find is that when Curaengine prints the first layer, it prints the outer perimeter and then starts printing the circular holes inside the perimeter without retraction. This causes a lot of stringing and some of the holes slide off. How do I enable retraction on my first layer so that no stringing occurs?
I have tried the following print, https://www.thingiverse.com/thing:2741800, and it prints perfectly with retraction working as it should, but I notice that retraction does not happen when holes are within a perimeter.
Is there a setting that can enable retraction within perimeters on first layers?
