Is my UM3 tip dragging?

[Croy9000 1]

The infill of my print is looking very raggedy in one section. It sounds like maybe the tip of the print core is dragging though it maybe. I hear a crisp popping sound as it goes through that section (and one other smaller mangled section). You can see the issue and hear the sound I am referring to here:

Throwing darts here, but it seems that you may have a thin part that has a bit of curling happening at the edges. It would mean the plastic is lifting and not that the nozzle is dragging through the parts although that would be the result on those edges..

Maybe you could try to trap the heat in the printer? Tape a piece of cardboard or bubble wrap over the opening.
