STEPPERONLINE Nema 14 Bipolar Stepper Motor 0.8A 25.5oz.in/18Ncm 3D Printer CNC Machine

No problems with this stepper. It's fairly quiet, smooth and does what it's supposed to do.

I use a lot of steppers and I've had great luck with those from StepperOnline. I typically use larger NEMA 17 or 23 units, but these little 14 models are very useful for smaller projects. I used them for rotators and focusers on small telescopes and guidescopes. The dimensions are accurate and the mounting threads are clean.

X axis was skipping. It seems the bearings in the X axis stepper had failed.This unit was a direct replacement except for the fact that you may need to attach the original servo plug to the end of the cable. Running Solidoodle 4 with ATMega + RAMPS1.4.

These are great little motors and ultra-quiet. BUT it's REALLY important to look closely at the documentation on this page. They are rated for 5.4V not the typical 12V you normally see for steppers. If you hook these up to a 12v supply they will stutter and stagger and you will be sad. Hook them up to 5v and they are quiet and smooth.Also mine came with a nice little sheet with all of the relevant information, so not sure why some are saying no docs.

These are quiet. I hate the fixed wiring - but you can’t get NEMA14 steppers with six-pin connectors anymore. What’s with that?

Works fine

No documentation. I've looked on line and can't find much. It does appear to work. I'm using it with an Arduino.

Ordered for accessory for my steam engine.
