UM 2+ and Ninja Flex


Recommended Posts

Posted (edited) · UM 2+ and Ninja Flex

I have been trying to print ninjaflex on the UM 2+ and I haven't had any success. I have unscrewed the extrude and pushed the filament in myself and when heating is does come out the tip of the extruder, but once I begin printing then nothing comes out. I believe that when the motor is pushing the filament into the extruder it is curling up since its a flexible material. Any tips on how to fix this?
