I have been unable to print anything using black NinjaFlex 3mm filament with my new Flexystruder v2.
It is installed on a TAZ4. Trying to print a simple washer at 230C using Slic3r 1.2.9 and Printrun 2014.03.10 This setup has worked fine for more than a year using the standard extruder with ABS, PLA, and some other special filaments. I used the NinjaFlex-0.5nozzle.ini downloaded from the Lulzbot website.
I don’t think the gcode is the problem as the first step of trying to extrude 10 mm of filament ends up in a jammed hotend. This even happens at hotend temps up to 250C. It pushes out maybe 1 mm and then the stepper motor begins to lose steps trying to push more filament out. I cleared out the hotend and feed tube and found a curled piece of NinjaFlex with scrape marks from the drive hob bolt.
What is the magic thing I am missing? Do I need to convert to Cura or reflash the Rambo card?
