Up until November of last year, I printed on a Stratasys Dimension 3D printer and one of the things I hated most was coming into a failed print because of a loss of extrusion.
Getting a Lulzbot TAZ6 has been awesome on so many levels. The number of materials I can print with, MUCH cheaper cost of printing, great online community, and the ability to do modifications. The one thing that is tougher is the learning curve. On the Dimension, I’d just upload my STL and print, no settings to tweak. On the TAZ, while much better, it is much more complicated.
I have been working on a Loss of Extrusion sensor with the goal of sensing filament run out as well as the filament not moving. Because of my lack of experience on 3d printers of this type, I wanted to ask for feedback from 3D printing veterans in regards to how this sensor should operate. ie What is the slowest speed a filament could move? At any time during a successful print, does the filament stop for any reason?

Thanks for any feedback!
