What is causing this to happen and how do I fix it?
this could be a lot of things. Has it happened more than once? Does it happen with different models at the same height?
If this is a one off it might be nothing really a tangled filament would be my first if it is only this model there is like a flaw in the model or slice. If it is every time every model at the same height Look very carefully at the filament path and see if it is pinched or obstructed when at that height. The images show some stringing and odd stray filaments in the infiltration. my gut says it is the model or slice and I would try something else that is similar height. But this is a best guess.
This has only happened on this print however it happened twice at different heights of the print.
If every other model is fine I is likely he model is self.
