    I purchased the 3-pack of the smaller steppers for my current ender 3 pro project. For my applications, they work perfectly. It's a great deal for quality motors, and I'm going to purchase another 10 packs.

    These are great motors and they are very strong. They are operating quietly, and also need them to release their hold every time a move is complete.

Selecting a Planetary Gearbox

When selecting a planetary gearbox for your application it is important to take note of;

 

Specifications required – torque, backlash, ratio etc of the application must be taken into considerations.

 

Environment – some environments may leave a gearbox exposed to dust, dirt or moisture so it is important to consider this factor and select a gearbox with the correct protection.

 

Space – planetary gearboxes are available in various sizes, if there is limited space available then a smaller gearbox can be used.
