Bondtech is great but I don't think it will help you on ninjaflex. I assume it wasn't a bowden printer in the video? I have a bondtech on one of my printers and I'm pretty happy with it. Although the UM2+ feeder (the white feeder - not the black feeder) is easier to load and unload filament. bondtech is good at this but not as good as the "plus" feeder.
But Bondtech has about twice the pushing strength. So it's great for really fast, low quality prints.
But for ninjaflex not so much. It's like pushing on a string. You can push harder but that string isn't going to move any faster.

I've been printing with Cheetah for a while now with varying degrees of success. BuildTak sheets help a lot in keeping parts stuck to the bed. My usual print settings are:
Print Setup:
Nozzle: 0.4 mm
Layers: 0.2 mm
Speed: 20-30 mm/s (all)
Fill Gaps Between Walls: Nowhere
Retraction Extra Prime Amount: 0.128 mm^3
Material Settings:
Temp: 235º
Bed Temp: 70º
Fan Speed: 100%
Flow Rate: 130%
Retraction Length: 6.0 mm
Retraction Speed: 20 mm/s
I have had some success printing smaller layers but if there are too many retracts it begins to under extrude and if you reduce the retraction length you get a lot of stringing. I've thought about buying a Luzbot just for doing Ninjaflex as it has a direct extruder instead of a bowden.
Edit: Thought I should add that I've found keeping the filament dry is critical. Any moisture will cause under extrusion.

I shared my experience with it recently...

Has anyone had any experience with the Bondtech extruders? They have a video of them printing ninjaflex at 60 mm/s and I was wondering if it would be worth the upgrade?
