Usongshine Nema 17 Stepper Motor Bipolar Step Motor for Titan Extruder 3D Printer 4.1V 1A 13Ncm (18.4oz.in) 4 Lead 1.8 Deg with 1m Cable (17HS4023)

I bought this motor for my Ender 3 Pro to use with a direct drive setup, and it’s been working perfectly. It connects straight to the original stepper motor cables with no adapters or wiring changes needed, which made installation super easy. The motor is strong, reliable, and fits great without any issues. There was no noticeable change in print quality compared to my previous setup, but that’s exactly what I was hoping for — everything works just as reliably as before, just now with the benefits of direct drive like easier filament loading and better handling of flexible materials. If you're upgrading to direct drive on an Ender 3 Pro, this motor is a solid choice.

Update: I’ve had this motor and extruder for a while now and have had 0 issues. It is working amazingly well, and has plenty of power to push filament through. The BMG style extruder was something I always wanted to use but I needed a pancake or Slim motor to be able to utilize it. After trying out the TwoTrees Magnetic flexplate I found their quality to be pretty good compared to other manufactures so I decided to purchase their BMG extruder and this Slim Style pancake motor. I was worried about the motor having enough power but it is working amazing with their BmG extruder. The installation instructions were very plain but installing a motor is relatively simple. After double checking that the wiring diagram of the motor and the wiring diagram on the board I am using are the same I proceeded to connect everything. I was lucky that I did not need to change any of the pin orientation but some users might have to change them in order to get the motor to turn in the correct direction. With the instructions followed and everything assembled I started my set of calibration tests. After everything was done I was able to get some fantastic prints with in these last few weeks. This motor and their extruder have been working marvelously and I will update this review if anything changes in the future...

Motor works great, does get hot, so best with a metal or high-temp plastic bracket. Too hot for petg.

This little stepper is great so far. However I did purchase with the intention of using it as a direct drive extruder on my ender 3 WITHOUT a gear reduction. This did not work well as this little guy isn’t powerful enough to do it without skipping steps. I will try my luck adding a bmg for gear reduction to see if it will work. This did however drop right in as far as fit goes. The wire was unneeded as it plugs right in and spins in the correct direction. Although that may change if a geared extruder is used.

With 3d printers, I am always discovering a new problem to solve. That was the case with my Artillery Sidewinder. The extruder would start clicking like it was clogged, but touching the feed wheel would start it up again. After some digging I found other people that said the stepper needed replacing. This is a direct replacement. With some effort, I was able to remove the 4 Phillips head screws in the back and replace them with the ones from my printer. The printer is back to work and doing great.

Really happy with this motor. The extruder on my X1 stopped working consistently and would "freeze" during long prints until you turned it forcefully, at which point it would spin up again. I replaced the stock extruder motor with this and haven't had any problems since. Mounted up just fine. Note: You'll have to remove the 4 screws on the backside of the motor in order to mount the extruder PCB and the plastic cover.

The stepper reached 70C at normal current settings. Lowered current and temperature was lower, but it began skipping steps on retraction with a FDM 3D printer. Also, the description says it is a replacement for the E3D Titan stepper. The shaft is shorter than the E3D Slimline, which has a 24mm shaft. The longer shaft engages the alignment ring on the outer Titan shell. Put in the real deal E3D Slimline, and at the exact same current settings, it worked perfectly reaching 48C max. Junk, don't buy

I wanted to make my Ender 2 direct drive but needed a lighter stepper motor for the extruder, so I swapped it out and the weight savings were immediate. It runs cooler than the stepper motors that came with the machine and is able to handle the torque of the original stepper motor with ease. Would highly recommend to those needing some weight savings for their printer.
