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

Worked well seems to be nice motors.the only problem I had is I had to swap pins 3+4 on my machine connector for them to work. Elegoo neptune 4 pro

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 20230716 After 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 purchased these for an Arduino project and they worked great.

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.

I have bought so many of these. They really get the job done. They seem well made and have lasted me a really long time.

I should have read the description and not relied on the picture as it shows 3 but you only get one. Just a little disappointed but work as intended

Otherwise THE ONE MOTOR you do get works awesome.

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.

Se estropearon los motores del eje Z, los sustituí con este motor sin tener que cambiar cables ni nada. Va perfecto.

Fonctionne parfaitement bien, imprimante 3d dépannée.

Perfetto per la stampa 3d utilizzato su fdm

Everything as described
