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

Had an X-axis issue in my ender 3 V3 SE which honestly I don't even know where it was coming from. Upgraded the lead screws and still had the same issue, upgraded belt, bearings etc. Nothing. Bought this stepper motor installed it and changed the rotational steps by half in klipper and problem solved. The connector for the factory harness with no changes made to the pins etc. Very happy with the purchase.

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

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.

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.

First I was excited about this 0.9 degree stepper motor but once it arrived and tried to make it work I got disappointed. Wiring connections are toooo small and apparently it is aluminum wiring. I made a simple test (step high = 1.25ms and step low 1.25ms, this is really slow motion) using A4988 driver which for faster test is the one I usually use (I prefer DRV8711 for more complex applications) and in fact it started working moving step-by-step so I decided to lift it from the bench by taking if from the shaft in order to test torque. Stepper started loosing positioning after 3 or 4 seconds, no motion (no other load than motor itself), current was like crazy so I turned off power supply and start over. No more motion/positioning was observed. No more than 30 seconds of use and it is dead. Even over bench table, no external load, no motion was observed again. How to ask for refund of this item? Is that possible?Updated 20230716After my previous post where I got defective stepper motor I was reached out by StepperOnline Customer Service asking me how they can fix my problem.. they offered me two options: 1) refund of money or 2) product replacement. I decided option 2 since I'm very interested on testing/evaluating this 0.9 degrees stepper motor. Today I received and plan to do some testing next week. Thank you StepperOnline Customer Service. This just deserves 5 stars.

I'm using it on an extruder for a 3d printer, I have a custom setup that I wanted a 0.9° stepper for. It very much may be my driver board, so I don't entirely fault the stepper motor for this yet (motherboard is my next upgrade, its needed now I know). Whenever it is printing steady lines, it's fairly quiet, fairly normal sound. But when it is jerking the filament back for a second, it's fairly loud. Which I'd really only a problem in fine detail printing.And again, it might be my motherboard, I will be updating this review when I get a motherboardAs for the positives, it's a much finer detail for my prints which is very nice, I did definitely notice a difference. The double number of steps help to smooth out the extrusion, so at least for me it helped a lot with overhangs

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

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.
