e3d nozzle jam. My fault?
This is my first time printing on a newly built printer, so I'm wondering what I did wrong. .40mm e3dv6 nozzle heated to 250degC, starting extruding 3mm ABS at 15mm/s. Within 30 seconds the filament stopped feeding, and when I retracted it the nozzle was jammed.
Disassembled, confirmed the heat break was free and clear, with the plastic stuck solid in the nozzle. What could I have done to cause this "hollow" jam?

I'm currently switching over to the magma hotend while this soaks in acetone.

When I get a huge jam I use a torch and burn the jam out.

Heat gun works just as well without the flame.

starting extruding 3mm ABS at 15mm/s
If the former, you are trying to extrude (1.5^2)*PI*15=106 mm3/s which is way too much for any hotend I know of.
