- Reviewed in the United States on March 7, 2025The motor works very well although the top speed is rather sluggish. The motor has excellent power for being a direct drive motor and the transition between steps is very crisp. A very delightful stepping motor to add to my shop!
- Reviewed in the United States on October 1, 2024Initially purchased one of these motors to replace the Y-Axis (Bed) Stepper as part of an Ender 3 to Voron Switchwire Conversion- figuring that a higher torque stepper would serve well.
The stepperonline brand was recommended by several members of the Voron community, and I have to say, these do not disappoint.
Packaging - 9.5/10. These steppers arrive to your door in tight fitting boxes filled with impact protection foam. While I would've liked to see some additional packaging around the shaft of the stepper, there is absolutely no room for the stepper to get jostled around.
The datasheet card inside the box CLEARLY outlines the wire color and coil assignments in a standard, easy to read notation that makes hooking these up to any mainboard an absolute BREEZE. So refreshing.
Build Quality- 9/10. Fit and finish on the exterior casing across both of the motors I've ordered has been consistently good. No rough edges, defects, or manufacturing residues were present. Motor shafts were clear of contamination, straight, and in good shape. The D-notch in the shaft is well cut.
Wiring appears to be of good quality and a higher gauge than necessary given the voltage and current. Zip ties across the 1m long cable were placed consistently and held the cable together well with no obvious loose spots. I took off 1 point here because I would've liked to have seen some strain relief (or at least potting) where the wiring joins into the motor for added durability.
You can leave the zip ties on, but I promptly clipped them off and wrapped the cables tightly in flame retardant automotive grade wire loom tape to extend their lifespan.
Performance 10/10. Thanks to the D Shaft and a little bit of threadlocker, clamping on 20t GT2 pulleys tightly is easy.
These motors have a 2A Current rating, but I run them at 75%- or 1.5A. This current coincides perfectly within the limits of a TMC2209 stepper driver, leaving you plenty of headroom on both the motor and driver so neither particularly stress each other out.
In initial testing at 1.2A with a very under-tensioned Y belt, this motor produced a recommended max velocity of 250mm/s slinging an entire bed around. That's a pretty phenomenal result given the circumstances.
In the 3D Printing Space, the 24V 2A architecture represents the point of maximum performance per dollar spent- and this motor is the perfect way to max out that ecosystem.
- Reviewed in the United States on January 21, 2024had no problems.. great buy... requires mods to power supply housing to fit to stock y axis. not bad tho
- Reviewed in the United States on January 18, 2025Came well packed and secured. Some documentation on wiring.
Upon visual inspection it looks great. I do have concerns over the fact that the power leads come out of the housing with no visible wiring support and the fact a person can look into the case and see the coil runs. I new it didn't have a pin out when ordering it but never thought the wiring would not be supported at this place with no dust or debris blocking.
Easley fixed with black silicone and heat shrink and a wire zip tie. I'm hard on things when doing R&D and especially on the D side as I'm old school and don't have the fancy tools and shops some have. And when building from scratch an item may under go several changes and assembly disassembly processes before being ready to use. This being my main concern over the wires out. So I moved to secure them better.
The motor works great so far and the small all in one controller/driver it's been paired with. It's very quiet for the most part. I try to test it's functional status after each assembly disassembly processe .
If I don't wreck it before I'm done with the d side and don't need to purchase a new one it'll be great. So for 20 cycles of assembly disassembly of the machine works and it still works as needed. Probably 20 more before unit is complete and being used but I'm no longer worried about the wiring harness. If I don't break the internal encoder wheel with all the jossiling and bumping and other great. If the motor comes out working still after everything then that'll be great testoment to it build quality. German built I imagine it'll hold up and keep on ticking. If it breaks I'll credit it to me and not the manufacturer, order a new one and keep going.
These seem to be really good motors for the price point. I will be buying more of them for future projects.
Everyone I know using these nema motors has good things to say usually. Only thing I've noticed is that if your math is off on prep of microsteps and degree of angle you're going to be off on your targeted stopping point or end up with drift. Easley fixed with encoder settings and proper math . So for my needs anyway.
There definitely no end to u tube videos on the subject either or at least it seems.
My really only other real complaint is that there is know paper lay out for mounting holes. A paper or plastic template for mounting holes would be great and trust me when I say it would be worth any extra expense for it. Some people would complain about it but I'll bet they'd be the first to use one. Not all of use possess the accuracy needed to lay out a simple pattern and drill it out the first time.
Four stars until I know how it holds up under use. Real use. But I really don't think I'll have to buy a new one anytime soon.
- Reviewed in the United States on January 11, 2025This motor has worked well for me. High quality, low noise with the correct driver, and high quality build. Just be sure to power this device correctly!
- Reviewed in the United States on November 29, 2018I needed a new motor for my Prusa 3D printer. It was skipping and erratic in Y axis movement. After isolating motor failure as culprit (by switching X/Y motor inputs on the raspberry pi motherboard of the printer and observing failure of Y motor with X commands but working X motor with Y commands), I decided that a cheap trial would be to order a new motor and hope that fixed the issue. Got it next day and simply unplugged the old Y motor lead and plugged in this new one via its attached clip. Worked well through the manual command movements (no adjustments to the 4 wires' position needed for me), so I fished the wiring through (wire length sufficient) and replaced the motor bolted on. test print was dead on, so I wrapped and zip-tied the wiring back in place. Slightly longer than the stock motor so I adjusted the Y-belt tensioner (at the front of the machine) to proper alignment. Many prints later, I am very happy with performance. All working as new. This is the great thing about open source hardware.

Nice Stepper motor it a small motor but working grealy.
Only thing is the price, it is bit costly.
