How do I choose the right stepper motor for my homemade 3D printer?

I'm assembling a DIY 3D printer and want to buy stepper motors from https://www.oyostepper.com. Which model (e.g., NEMA 17) would you recommend for the X/Y/Z axes? Are they pre-wired or do they need to be wired separately?
Also, how do I check its compatibility with development boards like Arduino/RAMPS?
Any suggestions would be greatly appreciated!
For a DIY 3D printer, NEMA 17 bipolar steppers are the standard choice.
For the X, Y, and Z axes, aim for a holding torque between 40–50 N·cm (approx. 1.5A rating). This provides enough power without adding too much weight, which helps avoid "ghosting" in your prints.
Don't worry if the motors come with bare wires; that's normal. You'll just need to crimp on JST-XH connectors or solder them to match your control board (like a RAMPS or SKR).
use a multimeter to identify the coil pairs before connecting, as wire colors can vary between manufacturers.
As long as you match the motor's current limit on your drivers (like the A4988 or TMC2209), you’ll be good to go. You can find more specific specs on motor types DFRobot Stepper Motor Wiki
