Currently, I am using Slicr with Repetier. Just completed a test with the speed turned up to 100mm/s. The issue is still present,. Watching the extruder tip closely it almost seems that the tip is dragging in the previous layer, if that makes sense, there is no pla on the extruder tip, which is a .4 to answer the previously asked question. The tip and pla measure correctly. There is a ptfe tube in the hotend. I'm going to attempt a print in Cura out of curiosity.
