    It is going to cross that area twice every layer...no way to avoid it.

     

    try different retraction settings, printing slower/cooler, to help minimize stringing.

    If you print slower it will have lower pressure in the head and will do less stringing.  For example 35mm/sec.  Usually I have zero stringing - you can look at my prints carefully and you can't tell where it travelled between parts.

     

    Also it helps to have *all* printing speeds the same (by default they vary by about 2X).  Each speed change causes quality issues like this.

     

    Some filaments (white filaments of all brands and plastics - pla, abs, all brands) string more.

     

    If you retract too much you will get air in the nozzle you get more stringing and also that will make prints ugly in other areas.  If you retract too little you get stringing.

     

    Set travel as fast as possible without losing steps.  On any ultimaker printer you should be able to travel at 200mm/sec or faster.  I think 150mm/sec is the default which is fast enough.
