So no one has a working spitfire then?
I'm sorry I hate to be "that guy," but this extruder just is not working. I have to stop it every 4-6 minutes remove the filament, cut off the end that has been stripped, and replace it. Which is not a viable option.
I've tried many different temperatures, types of Filament, speeds, flow rates, adjusting the current, cleaning the gear, everything I've read and can think of, but it still does not work.
It runs for a few minutes then I hear a "ggrrrt....grt.....grrrrrrrrrrrrrrrrrrrrt" sound, and if I let it go it will just miss layers destroying the print.
I am not at all pleased with this right now.
I bought this printer, and built it from the kit fully expecting trial and error, but I have absolutely nothing to show for my work.
Any advice is appreciated.
