Why is my stepper motor vibrating?
Stepper motors should operate over all speed ranges without vibration. But real-world steppers vibrate when running at low, middle and high speeds with what’s called rotation vibration. That’s because rotor speed varies between each move to a main step angle. This is just one example of how controls address vibration.
How do stepper motors reduce noise?
One trick to reduce audible noise is by increasing the microstepping level and step frequency together, while maintaining the same motor speed. By selecting a microstepping level which places the step frequency beyond the audio band, quiet motor operation can be achieved.
How do you stop a motor from vibrating?
An easy method to reduce vibration is to install a clean damper on the rear shaft of the motor. Clean dampers are basically hermetically sealed plastic cases with an inertia body packed with silicon gel. The extra inertia and silicon gel help absorb the vibration and provides a stable damping effect.
How big are the motors on a Prusa stepper?
The Prusa supplied steppers are 36mm (X, Y) and 40mm (E), so you may have to make some adjustments to get larger motors to fit. There is another option and that is to purchase an “upgrade kit” from Prusa, and that way, you would get a spare hot end, probe, motors, printed parts, bed, hardware etc.
Is the E3D stepper the same as the Prusa i3?
The E3D stepper is 38mm in length whereas the Prusa motors are 36mm? (or maybe 34mm) (X, Y) and 40mm (E) and from a different manufacturer. They will in all likelihood perform in a similar manner.

Is the NEMA 17 stepper motor the same?
They are fairly regular NEMA 17 (approx. 1.7″, 42mm) motors, but these do come in a wide range of specs. Basically (but not always) the longer they are the greater the current handling and power output. If you get a spare of similar size to the originals, they should work the same.
Are there any stepper motors with threaded rods?
You can even get motors with threaded rods, for example: http://www.banggood.com/42-Lead-Screw-Linear-Stepper-Motor-1_5A-40mm-300mm-Rod-For-3D-Printer-p-1048041.html What I found was that motors of a higher current rating are quieter when run with lower current.
