STEPPERONLINE 27:1 Planetary Gearbox High Torque Nema 17 Stepper Motor 3D Printer DIY Camera

Has worked well so far

The stepper motor with 27:1 planetary gearbox arrived in just two days from the time of my order.The motor/gearbox was shipped in a very good box with very good foam padding.The motor was brand-new as advertised and looked very nice.I tried the motor out on my system using a Raspberry Pi 3 B+ with a simple Python code. I was able to drive the geared motor with an L298 driver. With just 5 volts on the driver, I could drive the stepper motor.The motor behaved exactly as a bipolar stepper motor is supposed to behave and the shaft rotated quite smoothly, using 0.05 seconds for each pulse that went from the GPIO board (four outputs pins ) to the four input pins of the driver. Very impressive system for around 40 dollars.If you do not have time to build a planetary gearbox for your NEMA 17 stepper motors, then this will be perfect for you.I am rotating a piece of apparatus that weighs about 5 -7 oz , that has a relatively small moment of inertia. This STEPPERLINE motor worked great for me. Thank you.

Nice high torque but the small amount of gear slop made it un useable for the application I needed.

Used for a clay extruder. Very quiet and dependable. I just put it into service recently and this thing is strong enough to pull stumps!I was concerned with it having the nylon gears and they do offer a metal screw model for more $ but so far so good. It’s nice to know I have an option...

I am using several of these to open/close doors in a display. The gear ratio is high enough to get good acceleration control and low enough that they can be back driven if someone moves a door manually. Original order of 12 was lost in shipping but quickly replaced.

this motor worked great... plenty of torque and average noise for these motors... I'd buy another if I needed one

It fulfills my needs perfectly. Very strong and reliable.
