Well crafted works great, I've never had issues with their products

The motor runs smooth with good torque at low speeds. I used this with the TMC2208 mounted straight out, driven by Arduino with no UART connection. The higher speeds with 24 volts were limited on this motor to about 250 rpm. At speeds above 50 RPM, the noise level increased (expected).

I've dealt with Stepperonline a few times and have always found them to be a premium product at a fair price.

Skips steps or locks up at anything above slow speed(75rpm). Wish I could return this stupid thing, but I missed the window by two days.

this motor has the same issue reported in many other reviews, it gains a horrible vibration above slow speeds. I was going to write it off, until I learned more about how stepper motors are assembled.If you're willing to also get a sacrificial motor (34mm long, 200steps/rev) or have some laying around, you can transplant the core of this motor, with it's dual shafts, into a good motor housing. I also replaced the bearings, which are 5x16x5mm. the bearings that were included with the motor seem fine, so I don't think thtat they were the issue, but better safe than sorry. with the core and new bearings in a new 34mm housing, I had the 34mm dual shaft stepper motor I needed, and it runs great.Since I was using bearings and a sacrificial motor I already had, my cost was low, but even with those prices included, I think it will still be one of the cheaper ways to get a dual shaft motor, especially if, like me, you are impatient and want it shipped quickly with prime shipping.

The front shaft is only 20mm long. That's 5mm shorter than any NEMA17 stepper motor I've seen and too short to be used to drive a dual gear extruder on a 3D printer. It also has a short body which means less power/torque.

wonderful description perfectly fits in my project thankyou so much .I recommend people to read the description before they buy

sadly, these only go half as fast as my existing steppers from Robotdigg. Guess i will have to return these and just wait longer. These steppers rattle themselves to death at even medium speeds. I even tried lower current, which helped a bit but not much. They do work fine at low speeds, but I really cant use them for anything. And they were so nicely packaged and were delivered quickly.

The shaft is really short. I am using it for a model railway turntable and once I've added my slip ring and a rotating index pointer there is not much shaft left for the turntable bridge.My Arduino sketch expected to be able to use TX. First, the device is labeled with "TX" in what I call pin postion 5 (I don't know the proper way to identify pins) but the printed card just says "PDN" for both the "TX" and "RX" positions. With a lot of help from ChatGPT I determined that there is no "TX" at all.
