What causes this "stringing" and can my print recover from this? Here's what it looks like


This is the model
thingiverse linky

It looks like it couldn't print the edge, but this happened many many hours after printing the brim.

This did not happen with my 1st attempt at this print. The last print lost adhesion and I had to scrap it. This time, adhesion looks good so not sure why this happened.

Printing with Monoprice Select V2 with ABS, sliced with Cura. 100C bed / 250C extruder. 15mm/s initial layer speed. 60 mm/s print speed.

Update
It looks like the printer is starting to smooth it out like so. Still not sure if this will lead to an ok print or will fail because of this layer.
And it seems the stringing area does not have a brim underneath it. Did Cura just not calculate the brim size correctly?


Update2
Here's a few screenshots from Cura to show that the model is lying completely flat.



I let the print go on overnight and here's where I stopped it


It almost seems like the print shifted completely after printing the initial layer. Have you ever seen anything like this or is there anything in my Cura model that would make it do this?
No, your problem is not related to slicing, this is a hardware problem. Your complete print has shifted, this is called layer shift. 

This could happen when the nozzle hits an obstruction while printing while the Y stepper continues. This could lead to skipping teeth on the belts, slipping of the pulley or missing steps. This results in printing over air as the print progresses. This manifests itself as stringing, but in fact is unsupported printing (in the air). In this case it is unrecoverable as the printer has lost the reference frame, it just continues to print with the new reference frame caused by the layer shift. 

A Prusa MK3, or any printerboard using trinamic stepper drivers would be able to recover (if the belt and pulley are correctly attached, and steps are missed) as the skipping of steps is detected, in case of a Prusa  MK3 the machine will re-home when it detects skipped steps and continue printing. See also this answer for more details.

Possible solutions are increasing the belt tension, increase the stepper torque by increasing the current through the stepper drivers or re-tighten the pulley on the stepper of the Y belt.
