This is a quite amazing and interesting product. Before knowing about the closed loop system, I always had to reduce the speed of my stepper motors, to be sure not to miss a step. With the closed loop, I can speed up my motors because the feedback will recover the missed steps.

As described and arrival ahead of schedule. If I ever need it again, I wouldn't hesitate to buy it again. Highly recommended for 3d printers. In addition the electronics can be changed to more amperage motors such as the 1.7 A nema 17.

Tal y como se describe y llegada antes de lo previsto. Si lo vuelvo a necesitar no dudaria en comprarlos de nuevo. Muy recomendable para las impresoras 3d. Ademas puede cambiarse la electronica a motores de mas amperaje como los nema 17 de 1.7 A

Is running perfectly.

Läuft einwandfrei.

I've upgraded my core xy printer with two of these. Now it prints at such a high speed that I need to stiffen the Frame to deal with vibrations. Great servos.

Perfect in combination with Arduino or Raspberry. Only a digital pulse is needed, no stepper driver anymore! Fast and correct delivery with tracking. Thumbs up!

Stepper motor works as intended. Some pins on the PCB were bend and hat to be bend back. All in all good quality and nice value for price.
