Hello!
I’ve been trying to get Ninjaflex to print on a Lulzbot Taz 6 printer, and while I believe the settings I have to the filament are all set, I’m having issues with the filament bunching up underneath the Idler and the hobbled bolt. I can see that it is feeding into the extruder/hot end for a few moments but then it gets stuck and I have to undo the tension and allow it to get unstuck, though that is obviously not an efficient process. How could I avoid/fix this issue?
Thanks in advance for any advice!

The standard Single Extruder (not to be confused with the SE) is not designed for flexible filament.
For that, you can buy the SE Tool Head | 2.85 mm | Single Extruder | 0.5 mm or you can print up the body ( https://download.lulzbot.com/TAZ/accessories/tool_heads/version_2/Flexystruder_v2/production_parts/printed_parts/flexystruder_body_v2.0_for_hexagon/flexystruder_body_hex_v2.0b.stl) and transfer over parts to convert your Single Extruder into a Flexystruder. Assembly instructions and details are on the LulzBot OHAI site - OHAI: Open Hardware Assembly Instructions

Generally from what I heard half the speed of pla should work so I would start at 15 mm/sec then work your way up
