For the CF version I used 0.6mm hardened nozzle it is printed on Prusa MK3S. Other 3 TPU materials were printed on newly assembled Prusa MK4.
I noticed that it is very important to dry the filament (even if it is out of the box), but for this any cheap filament dryer is good enough (I used eSun eBox for this)
