Prusa MK3 lead screws for LR4

I recently upgraded a Prusa MK3S to a MK4 so I have two steppers with lead screws attached and 3 other steppers, along with an Einsy board.

Is it possible to use the Z axis motors with attached lead screws for the Z on the LR 4?

These are NEMA 17 but I can’t find specs with high confidence. I think they have a “push force” of 11KG and a “detent torque” of 20mN. They are 1A per phase.

These feel like “you can certainly try” territory, but does anyone have relevant experience or comments?

That’s a third of what you should have, I am pretty sure you’d have major problems with lifting the axis. :frowning:

Well that answers that. Thank you, I’ll keep those steppers in the parts bin.
