On my Aerostruder tool head for a Taz 6, PLA filament is looping immediately as it comes out of the nozzle. I assumed that there was a some kind of partial jam in the hot end, so I have attempted numerous cold pulls with cleaning filament to try and get any residue or bits of PLA that might by lodged in the extrusion path. I’ve done enough cold pulls such that the cleaning filament is now coming out clean, but the pulls are still lacking the perfect conical shape that they should.
I have read on the forums that it is apparently pretty difficult to do cold pulls on the Aerostruder, so my question is, is there another way (other than cold pulls) to remove partial blocks on the Aerostruder? I am not really familiar with Lulzbots and havent been using the Taz 6 for very long, so it is likely that I am missing something. Still, I assume that this is a somewhat common problem with the Aerostruder. Any help would be greatly appreciated.
