This is the first time I'm using a motor in a project. It's a learning experience but this motor is working great in my tests so far. I'm sure the only reason it isn't lifting more than the 1.5 pound chain I am testing with is my Arduino-based (ie current limited) power supply. I'm working on a power circuit that will allow this thing to perform great.

Difficult to find the right combo of drive voltage, current, pw, etc, but it cooks fine now.

Excellent motor. Worked perfectly for my cnc lathe project

Haven't used a lot of steppers before but as far as I can tell run smooth and fairly quiet, solid IMHO.
