Description: These steppers are a great way to get things moving, especially when positioning and repeatability is a concern.
This is a Bipolar motor.

I used this motor to control a Z-Axis on a milling machine. It was hooked up to a ball screw and linear slide. I got a great feed rate and excellent positioning from it, all at a good price point.
I bot a set of these to experiment with and the work great!
I bought 3 for a 3D printer project. One was bad, with an internal short.
Contacted Sparkfun and they sent me a replacement, and gave me a store credit. Really stand-up customer service.
I will order from Sparkfun again, even though one of the motors was bad. It wasn’t their fault, but they still stood behind the product. Well done.
In trying to connect 2 of these motors, I found that a terminal strip I prieviously purchaced from SFE was very helpful, they look good too ( green, hee hee) .
I purchased 3 of these to replace the motors that came with my SeeMeCNC Rostock Max V2 Kit. I have them connected to a Smoothieboard 5x running a Smoothieware Fork by 626Pilot https://github.com/626Pilot/Smoothieware The Shaft does not have a Flat edge (D Shape). I plan to machine a flat edge but for now they run fine without it. I run them at 1.7amps and they haven’t gotten above 60C.
They have greatly improved the accuracy of my printer, and I am very happy with them. I highly recommend these to someone that is looking for a higher resolution stepper for there CNC machine.
These are drop in replacements for the steppers on the Robo3D x and y axes. They have half the step size (400 steps per rev instead of 200), so the upgrade allows 0.05 mm x and y precision instead of 0.1 mm. Just replace the steppers, make a minor change in the marlin firmware; change 80 (steps per 16 mm) to 160 in configuration.h. That’s it. An easy big improvement in surface finish and in printing very small details!
