Call the sainsmart tech team . There step me up with the Amazon link . The step motors are powerfull and silent . Go glad my 3d printer is fixed at a great price with an on time delivery

These are great stepping motors - I used them to build a magnetic coil winder and a positioning system for a monochromator shaft in a spectrophotometer.

it was perfect

These Motors came very well packaged. Everything worked as expected.

These are great 3D printer steppers, offered in the right quantity for a Cartesian style printer that uses 2 Z motors. A great price, very fast delivery... whats not to love? Thanks Stepperonline!

Funcionan bien y llegaron rápido

Wiring is not consistent across the product line. The pancake motor (42x23) I have has A+B+A-B- pinout The pinout for these are A+A-B+B-. You just have to swap the two middle wires if youre just making a lot of noise and not moving. Once you do that they work fine. Buyer beware!

Some of the best stepper motors Ive bought.

Everything works well as expected. I mean, that what you expect out of a product, right?

I have other products from this company that work just fine but these were far too delicate for anything I do. It could just be me. Im not the most gentle with things but I do know once you bend a motor shaft your accuracy will never be the same.
