Nema 17 Stepper Motor 42-34 3D Printer Motor DC 1A-3.4V 2 Phase 4 Wires 1.8 Degrees with 39.3 inch Cable for Creality CR-10 10S Ender 3 3D Printer/CNC extruder and Y-axis

Works flawlessly.

Works fine but the motor I received looks really used. Dents at the bottom and adhesive marks on the motor from previous usage.

dont buy this for a creality 3d printer

J’ai acheté ce moteur pas à pas pour remplacer le moteur de l’extrudeur de mon imprimante 3D Vivedino Raptor 2. Le remplacement s’est effectué sans difficulté et tout fonctionne parfaitement. RAS, je suis satisfait de mon achat ! 🙂

Incredible, I replaced the X and Y motors of my Ender 3 Pro with 42-40 ones of this and I was able to increase the acceleration from the default 500 m/s2 to 5000 mm/s2, and probably can go higher with a little more voltage, but I'm quite happy with the current speed, with the input shaper and the linear advance features of Marlin, now the printer prints 2.5-3 times faster with higher quality. Though the top speed is still limited with 120 m/s as the hot end can only melt around 12-12.5 mm3/s of filament. The model in the video normally prints in 12-13 hours, I was able to complete it in 5 hours, unbelievable... I increased the default voltage from 580 mV to 850 mV and that's it. The original motors, especially the X motor was getting too hot, around 50 °C, even with an acceleration of 1000 m/s2 and the aforementioned 580 mV input voltage. The new ones never go over 30 °C. I'm super happy and planning to buy another 5 of these to replace the Z axis and my MMU2s motors. Oh, I didn't need to change my printer cables, these were a drop-in replacement, my board is an SKR 3 EZ.
