3D Printer Filament GNVTNTP Filament Facts!

I just found out something interesting about GNVTNTP Coextrusion and Triextrusion filaments. In order to keep the filament strand from rolling and rotating in the extruder drive gears, they have introduced a very mild ovality in their filament, making it just the slightest bit elliptical. The upshot of this is that when your extruder drive gear(s) grab the filament it settles into the easiest way to move the filament forward and that little bit of ovality keeps the filament in line. The amount of change across the filament is very small, smaller than we can accurately measure with calipers, but it is possible on occasion for a filament runout sensor to be tripped as a result. If you have this happen, the suggestion from GNVTNTP is to disable or bypass the runout sensor for that job or filament and it will print just fine. I will gladly disable my runout sensor if it means the colors I have will be consistent. They said they have a process in place for the future that should eliminate this from happening. Exciting filament times.
