Shameless plug: Zesty Nimble extruder now on sale
-
I don't know but its a reasonable suggestion, although if this was such a problem why is flex3drive 40:1 and nimble 30:1, is it possible to make a worm gear drive at 20:1? if so why haven't they?

To my understanding the 30 to 40 range reduces the noticed effect of cable delay…. there is sort of a tiff between the two companies on that subject. Flex3drive believes 40 gives better precision while zesty nimble believes the extra is not needed and better speed comes from the 30.... anything less i believe shows too much of the delay effects in the print.
My theory (i am not even qualified but it seems to me) Is that the high gearing at one end minimizes the delay affect but to achieve speed you can reverse the gearing at the other end to minimize the downsides of the necessary high gearing at the other end using a small stepper and low power
basically youre not changing what the high gearing does, you are only lowering the steppers esteps and increasing the ability to spin that high gearing even faster

Hopefully someone more qualified in this type of thing can say if this is correct or not
