I am working on configuring a dual extruder system in E3D and would like to print ABS with the main head and support with a secondary head. This seems pretty straightforward, as I can set the temp for the individual extruders, and give them the correct offset. What I would like to see after processing, is how much material is being extruded from each tool. Is this possible? I need this info to size the filament rolls I will be buying and designing a combined dehydrator for.
