Hello all!
In short, I want to build a Fan Oarsman. It's a robotic nozzle that creates a fan water jet like those in the below video:
The robotic device looks like this:
I want to build a reduced size with a 5 m height fan jet.
My question is, can Nema 42 Stepper Motors be suitable for a project like this (to be used to control X and Y directions of the nozzle)? I wander if they are strong enough or if they are quick enough for this types of movements?
Thank you!
NEMA 42 just specifies the dimension of the motor faceplate (in "inches", of all things).
You will need to work out or measure the torque and speed required for nozzle motion and choose an appropriate motor.

NEMA 42 defines the mounting hole locations. It says nothing about the voltage or current that you need to supply, or the torque that will result.
I know that at some point I will have to do some serious tests but for now I wonder if is realistic to use a motor like this before I start a more serious reasearch and experimentation. I look for an answer from the intuition of an experimented person. The idea is thet I don't want to start to build that nozzle (and it's not simple at all) and the remaining pipes, connections and so on just to find out that I will need some actuators a lot more expensive that Nema 42.

Sorry. But you have that back-to-front.
Your question is a bit like asking should you use a Ford car to go to the seaside for a day before figuring out if there will be three people travelling or thirty.
Either the project is worth building, or it is not.
How could that possibly depend on whether your uninformed choice of motor mounting plate size is correct?
