I'd like to see a picture of the part you're printing, especially around the area where the filament jammed and at the bed directly below. My reasoning is that your jam might be caused by the part warping up off the bed causing the slight gap between the extruder and part to close up. I've had this happen innumerable times on large prints and the only cure I've found is to ensure that my part stays perfectly bonded to the bed. Tell tale signs of this happening would be any movement of the part (warpage) , as well as grooves in the upper layers caused by the extruder dragging through the plastic.
As far as remedies go it depends on the part. In some cases I've had success simply by using more hairspray for better adhesion, or raising the bed temp to compensate for the heat loss due to the increased surface area. Recently I've gone to larger and larger brim settings to help hold my parts in place, or even adding more layers to the brim to make them stronger. As always a perfectly calibrated machine and a clean nozzle are required before setting up a large print job.
