STEPPERONLINE Nema 17 Stepper Motor Bipolar 1.5A 42Ncm 42x42x38mm 1.8deg 4 Wires with 1m Cable and Connector (1 Pack)

I'm using TMC2209 and these are pretty quiet. Good response time, these are as good as more expensive options.

Nice steppers to upgrade for a printer. Just tested these. Good torque. The 0.9 hold their steps at high accelerations. Needed rewiring to work with my board as others have stated. Comes with diagram so no problem.

I got two of these stepper motors for upgrading my Prusa MK3.9S to a MK4S, replacing the X and Y axis motors with the 0.9 degree motors. These motors work great and perform well. However, I had to manually re-wire the included cable in order for it to work. The wiring information in the included data sheet does not seem to match the wiring indicated in the MK4S electrical schematic. Despite just some re-wiring, I'm still giving these 5 stars. Way better value than ordering from Prusa for identical performance. They change the noise profile of the printer, but I do not have a stock MK4S to compare, so I won't provide any opinion on the noise.

Really nice looking steppers, all movement free and buttery smooth, packaged very nicely, the card with wiring diagram and picture that shows where the positive and negative poles are in Avery convient nice touch to the package. Big deal if wires dont work for YOUR application. News flash people, they can't make wire harnesses for every single application out there that would be ignorant to think that. So they send the most likely wire harness that works with most. If you cant simply rearrange a 4 lead jst wire connector you shouldn't be messing with stepper motors in the first place. Get a grip and simply reconnect 2 measley freaking wires and don't get all bent because it doesn't work for YOUR use case

Cable isn't wired properly for the CNC shields and most stepper driver outputs, but that was a quick fix once I figured out what the issue was. Unfortunately, it took me two and a half days of debugging and pulling my hair out to figure out it was the wiring order and not something else.

So far so good

The media could not be loaded. These motors work perfectly in my diy CNC, I had to switch some wires due to the way my control board worked. They where able to move the components around but I am not sure it would be able to do deep passes, but that was expected. The motors did run a little hot after a while and sometimes presented high pitched noices.

The media could not be loaded. Really fast but i did have to cut a chunk out of my build plate support for the bed to go all the way back very high quality and i wouldnt say its quiet when running fast but if your going slow like 2k acceleration Its not going the be loud
