NEMA 17 MOTOR Enlighten me Please!

Guys I got a free prusa i3 frame from a buddy at work and I wanted to build it out into a fully functional printer since i have several more spare parts.

I have built one of these before from folger tech and i'm happy.

I need guidance on the NEMA 17 2.6kg/cm Stepper Motors

Are all these motors the same? I see used ones on ebay 3 for 20 bucks

The MK8 extruder im buying has one motor already but i need to know what i should buy for the two z axis and x, y axis. I found this document [reprap.org]

So im thinking the motor and the voltage compatibility might be a problem. I will use all the documentation and electronic settings just like the folger tech prusa i3 i built.

Thanks for the help.

I had similar questions in this post. You should find everything there about how to calculate the size of the motors you need and the associated electronics.

all nema 17 motors are NOT created the same!

Good luck!

Cool thanks

I have used 42BYGHW804 NEMA 17's off AliExpress.
