@PrintinAddiction it stops to move to the other part of the print. If you look at the picture, there is a gap in the middle of the part. It first prints the infill, then the inner wall and then the outer wall after that. When it’s done printing the outer wall, it stops for a very brief period of time so that it can retract and then move to the other half of the part. It’s during this short pause that the blobbing was occuring.
Since there is no extrusion at the moment of stopping, this means that the substance goes on its own. The temperature is high. Print a temperature test.
Simplify 3D (I use this) has a “coast to end” setting that stops extrusion before the hotend stops, so the nozzle is emptied and when it stops does not run out of the material.

I believe its a start of a clock because with my makerbots that get clogged I have noticed that on the filament before the nozzle got clogged completely.
i had same sometimes on cura, you must set the retraction little slower and shorter. Other thing is, try repetier host. its also free and better flow. i havn’t clogg any more since change from cura to repetier. but you can choose the curaslice engine in repetier thats a good combine. Other thing is in repetier you can set any speed or temperature live by pr
