Hi .I got a idea
Transporting the granules through a PTFE pipe in the same way as the filament do?
Gust the diameter of the PTFE pipe got to be bigger.
One problem has to be solved: instantaneous extrusion stopping.
Methods:
-mechanical retraction of the granules - how is the question
-vacuum the pipe - possible with a vacuum pump
-hot end with stop valve - has to be designed
comments please
