Great! Now my 3d-printer is not far from finished. Anyway, I have a further question: would this be a good choice for the z-axis? Would it work well with Smoothie/Duet? I would also appreciate some recommendations for the extruder stepper (I'll be using bowden extruder with 1.75mm filament). Thanks again!

For the extruder, I recommend using a gear ratio of between 3:1 and 5:1 with 1.75mm filament, and a stepper motor with 20 to 30 Ncm holding torque at full current, with a current rating in the range 1.2 to 1.7A (or 1.2 to 2.0A if using the Duet WiFi). I use JK42HS34-1334 motors and an extruder gear ratio of 34:11.

I'm curious, why the suggestion in geared extruder? Just for more torque at lower current with smaller motors? Or was there some other reason I'm not seeing?

I can't advise you on the mechanics, but in electrical terms that motor is fine for the Duet, Smoothie and most other electronics.
