Terrible Stringing on print of Manhattan


Recommended Posts

Posted · Terrible Stringing on print of Manhattan



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
