Is there a way that filament could be passed through something like a donut hole but the donut would be filled with water and calculate the volume displace by the filament?
Whatever way this goes, the system would be quite far ahead of the extruder and would require either a purge at the start of the print before it can start real-time compensation or a memory of some kind that would be rely on you not moving the filament or changing it.
