I bought a Genuine v6 from amazon through the E3D store page. All was well except it contained the old style heater block (designed for the standard thermistor and screw) but with all the new components otherwise. The Thermistor cartridge won't fit as it's too big for the hole in the block. Also, the silicone sock is too big and hangs off the edge. I have had it all refunded by amazon but I was wondering how this could have happened? I thought the new design was years old by now. The only other thing I can think is somehow it wasn't a genuine kit? But it was found through the E3D store page on amazon so I just can't understand it.
