realthor - in part i agree, in part i differ in view.
flying extruders on a delta are going to start introducing lots of harmonics to deal with when talking two or more motors, and realistically flying extruders are not cmpatible with other machine styles.

The inspiring video at the beginning of this thread - the over-riding thing i noticed was that it was not shown printing unless i missed something. I also seem to recall noticing the belt drive/motor mount setup looked a little suspect (cantilvered and suspended?)

These being said, the most we can do atm is to make one extruder setup that is light enough, and then attach 2-3 of them to the printhead, depending on your needs. Then dimension the rods/rails as fit and setup a proper speed for what we have.

Flex shaft weight is negligable since it is quite literally suspended/floating due to the arc taken by the ptfe tube within which it is housed.

But what is the number? If you don't want to share that's one thing, but I'm capable of determining what is "negligible" all by my self.

LOL when i say negligible I really do mean negligible. Im sure i said "suspended/floating" in other words, zero negligible nada. i didnt mean to insult your intelligence or capability

The shaft doesn't weigh zero, stop the semantics nonsense. I don't care how you suspend it, I want to know the mass of the shaft and its housing. Again, if you don't want to share that's fine, but it isn't zero. So again, not what you think the net effect is, mass of the component please?Quote

Would it be totally insanely out-of-the-box to think of two extruders working in tandem?
One big and mighty off-site and one small and puny on the printhead, one whose sole purpose is to match the speed of the mighty one and feed the filament into the hotend? These two can result in some sort of semi-flexi-drive for a fraction of the cost. I think that the puny one can leave without gearing altogether as its job would be to keep the length of the filament between the mighty extruder and it's own hobbed gear the same at all times.

I assume that strange noise was the piezo?
