I must be doing something completely wrong.
I am trying to print Marvin from thingiverse. I am using purple eSun HIPS and the eSun HIPS profile, loading the STL, and hitting print in Cura 18.04. Things look great to start. But, right around 50%, the print head stops extruding, but continues to move as if it is printing. This has failed 3x in a row now at the same place with the same symptom, and I had to send my print head in after the second attempt because I could not unclog it. What information can I provide to help diagnose why this is failing each time? I thought Marvin was considered to be a simple print, no?
