Terrible Stringing on print of Manhattan

Posted · 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. 

 

https://www.etsy.com/listing/1001618510/3d-manhattan-digital-files-3d-stl-file?ref=shop_home_recs_3&pro=1

 

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.

 

Michael

        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
