I installed two of these on my Ender 3 Pro, one on the Y axis and one on a belt-driven Z axis. Both have been working great with no missed steps or weird behavior. I’m driving them at 1.4A RMS, and while they do heat up a bit, the temps seem pretty comparable to the original steppers. No complaints so far. Planning to grab more for my Ender 3 Max when it shows up.
We are so happy to hear that and thank you so much for your support on our website. Any problem do free to contact us.
Best regards

My printer is broken. My friend told me that I need to replace the stepper motor. Then he recommended this Chinese supplier to me. Now my printer has been working for a while.
