Creality Official 42-40 Stepper Motor with Extruder Gear, 2 Phase 1A 1.8 Degree 0.4 N.M for 3D Printer Extruder, Compatible with E-axis of Ender 3/Ender 3 V2/Ender 3 pro/Ender 5/CR-10 3D Printer

Official replacement works great

Unfortunately I purchased a Ender 3 Pro that was highly damaged - I had to replace the stock stepper motor gear and found out that it is pressed on! I ended up removing it only to learn that the shaft is completely round causing the filament to slip. Such a pain! The Creality Official 42-40 was the solution and came with the gear that needed to be replaced. I am happy to report the printer is working like new :)

Can't go wrong with Creality stepper motors.

I thought I may need to replace a stepper motor. Turns out mine was fine, which was ok, as now I have a spare stepper motor when one does fail.

Even when brand new, my CR-10S always made a lot of vibrating noise when the bed (Y axis) moved back and forth. I should have had Creality replace this stepper motor under warranty. I got this and a stepper motor vibration damper -   - and the noise level while printing is much improved.The install is pretty easy, there are plenty of youtube videos, but just take a photo of how its installed before. Its pretty much just a few screws. Photos attached of the Y axis stepper motor. I believe these printers use the same stepper motor for all axes.If your printer is less than a year old, you should contact Creality for a free warranty replacement of the stepper motor before buying this. Even if you buy this too because don't want to wait for them to ship the replacement, you'll have a free backup and they should replace defective parts if under warranty.

el motor cumplio con las espectativas para la impresora, hasta ahora funcional

I was trying upgrade my filament extruder thing above the stepper motor, and my Ender 3 pro had a pressed on gear, after a bit of research, and buying this, exactly what I needed!

I wanted to upgrade my the plastic extruder parts on my Ender 3 Pro with the metal version. Unfortunately, my extruder had the pressed on extruder gear. I did get the pressed gear off but found the existing shaft to short. I wish I just ordered a replacement extruder stepper from the beginning.

Simple and straightforward to replace and works like a charm.

The media could not be loaded.  Lo uso junto a un extrusor clon BMG. El que viene con la impresora tiene el engranaje unido a el motor y no encontré la forma de liberarlo. Por lo qué decidí pedir uno nuevo. Si vas a modificar tu extrusor lo vas a necesitar.

Got this to replace a stock one where the piece can’t be replaced. it was easy to install and works the same as the old one.

Conforme pour une imprimante 3d.

Lo use para una reparacion de un CR10 y me fue genial.
