Very interesting little printer and it looks fast too printing filaflex. I guess that printing ninjaflex should be similar.
It’s only a preview but it looks promising and with a cool design. They are also claiming WiFi connectivity too.

Hm, I’m printing ninjaflex on my rep2x at 140mm/s right now. Can’t see why 150 shouldn’t be possible. But Ok, they need to make some advertisement. And I don’t like makerbot anymore. So therefor I hope this printer will be successful and open source.
@Sven_Eric_Nielsen That seems empressive! I am trying to print Ninjaflex now on my rep2x and I am having a problem with curling. Not with it sticking to the surface, but when you are printing something with even the slightest angle. how did you solve this?
I think, from the rumors I hear that it is going to be very competitive.

First of all reduce the Temps of the extruder. Of course it depends on the color and some other parameters, but I would try something around 220 when u print with high speed. If u print with lower speeds use even less temp.
The replicator 2x have a very bad extruder in general. I think u are already using the extruder upgrade. This is necessary. But to put the filament into the tube can be very annoying.
In the settings of the printer I recommend to reduce the temp for the extruder fan to 30°.
I also recommend to use some thermal compound between the cooling block and the cooling block and the heatsinks. Put the heated bed to something around 80° and the last magic trick is to use a big fan in front of the printer together with a completely open housing 
Thanks @Sven_Eric_Nielsen I will try my luck again with your recommendations

Let me know how it goes.
Unfortunately my ninjaflex is empty now. I think I should buy some new
Sure @Sven_Eric_Nielsen !
