[Terrible Stringing on print of Manhattan]

Hi, 

 

I've generally have been pretty happy with my settings in Cura for most of my prints. However, I am trying to print a 3D model of Manhattan and getting terrible stringing.

I'm using a direct drive Hemera extruder with a Volcano hot end. I'm printing PLA at 220 degrees, 90mm/s

 

I've tried printing a basic stringing tower, and just can't get rid of the stringing. If I knock the temp down to 210, I get clicking on the extruder. 

 

I've got my retraction set to 3.6mm, which I thought was high for a direct drive head. With a retraction speed of 55mm/s. And I have Z Hop on for Retracted. 

 

Do I need to just print cooler (at 210) and slow down? 

 

I'm a little stuck here and would appreciate some help. 

 

.4 nozzle, .4 line width, .2 layer height

 

Thanks.
