@zapta , that will be gr8 for some machines , that motor iis tiny , not sure if vibes from stepper would effect the delta with smart effector setup i use, but this looks gr8 idea

i did look at the nimble before getting the flex3drive , but the design of the flexdrive seemed more robust , and i noticed dc42 used flexdrive extruder on his delta kits

i could not be happier at this point had a couple so spools of filement through it so far and no clogs , filement path has zero restriction when changing material , even flex materials have no problems

i got a flex3drive to reduce weight on my delta and could not be happier , seems for most part a solid and functional design , changing out filement is a doddle and just getting it dialed in at moment first few prints are looking good and easy to get up and running

got retractions dieal in after a few prints and its harder to see but

the 4th benchy came out mint

huge improvement over my previous bowden v6 and bulldog extruder setup
