@o_lampe I did initially think of the cut alignment as an issue but I think the solution should be easy enough. My initial solution was to mount one roller set, feed filament and then thread the other roller set onto the filament and shaft at the same time for alignment. You may be absolutely right about the back to back design being more efficient though.
I did see discussion about the diameter of the threaded rollers in some places when I was researching this last year. I've got a micro pipe cutter that has a cutting wheel < 10mm, but I'm still trying to source replacement blades.

Re: Future development for the smart effector?

Has the development gone anywhere on this since the last update?
I would love to see some of the new methods we're seeing in the community combined with the last gen smart Effector features. From some of the load cell logic prusa is using in the XL, the accelerometers being used for input shaping, built in mcu and driver for wiring simplification and I'm sure a load of other tech I'm forgetting!

I think the accelerometer holds a lot of potential for deltas specifically. Delta calibrate could leverage them quite heavily to detect a true delta radius. Any concave/convex motion would show on the Z measure when moving between points in the XY plane. This could also be done at any height, not just at the print bed level. This could also be polled mid print to detect erratic motion caused by a possible print head crash/disconnect.

@oliof I'd be interested as well. Would this be a hollow shaft nema 14 round pancake?
I like the greater performance to weight of the ratio of the BLDC but I think I'll stick with stepper unless someone has a single board solution to running a magnetic encoder and simplefoc.

I picked up a hollow shaft nema 14 mentioned earlier in this thread. I'm planning to test with some hardened steel pipe cutter blades.

Has anyone used a dual shaft stepper with a push/pull configuration? If the back to back bearings bode well for pushing force, additional blade contact could do the same.
