Had some trouble printing NinjaFlex. We have been able to get good prints in the past.  
First few layers come out smooth, as print progresses the lines start to look inconsistant. (See Pic 2 of attachment)  
  
  
What I have tried  
-Adjusting Bed temp  
-Adjusting Printing Temp/ Speed  
-Adjusting Fan Speed  
-Cleaning Nozzle  
-Drying Filament

Ideas:  
Worn Hobb Gear?  
Heat Creep that shows up later on in the print?

NinjaFlex prints really well with the Flexystruder and the latest aero-based extruders. Reach out to the support team at [https://LulzBot.com/Support](https://LulzBot.com/Support) and they’ll be able to get you moving in the right direction.
