I have an Idea for the extruder but im not sure if its easy to implement.
Can there be a third Belt that will drive the extruder? It would need some software changes to move slightly faster than the printhead but it is doable, when im right.
This would eliminate the need for a bowden extruder but still keep the printhead lightweight.
Someone out there who want to try it? Or any thoughts on such a system?
