I am having a weird issue where it acts as if the nozzle becomes cold. I have attached a picture of the after math on the latest occurrence. The few times prior the filament went out the other side. The printer continues on like nothing is wrong. The weird part is it is only one one particular model that this happens to. I am printing "shark fins" for quads. The one the fails has a square base, the one that prints has an X base. I used exactly the same printer settings (Slic3r Prusa edition) when slicing the models. It also appears to happen at the same spot in the model, just as it is putting the top layer on the base.
Any thoughts?
