STEPPERONLINEShort Body Nema 17 Bipolar Stepper Motor 1A 22.6oz.in/16Ncm DIY CNC Extruder

I bought this to upgrade my stock stepper because I was upgrading the entire direct drive set up and wanted to shed some weight to help achieve higher printing speeds and this has worked perfectly. I paired with a genuine E3d Titan Aero extruder and went to thingiverse to print out a new carriage mount, motor mount, fan mounting bracket and bearings. Overall this new set up is about 25% lighter than my stock set up was and has been handling 100mm/s + no problem.For voltage settings after a few adjustments I have the run current at .75A and the hold current at .6A and these settings have worked perfectly with no skipped steps and the stepper barely gets warm to the touch.Just make sure to look up the correct wiring for this because it does not come with the JST connector and you will either need to install your own or splice it onto the connector form the previous stepper motor.Its been a few months since purchase and it works great

I used the Short Body Nema 17 Bipolar Stepper Motor for a motorized projector shelf project, and it has been exceptional. Its slim profile is a standout feature, especially when compared to other stepper motors, making it perfect for applications where space is a premium.Pairing it with a DRV8825 driver was a smooth process, and they work together flawlessly. The motor's performance is reliable and efficient, handling the movement of the projector shelf seamlessly. Its compact size does not compromise its power, which is impressive.For anyone looking for a stepper motor that is both space-efficient and powerful, this Nema 17 is an excellent choice. It's ideal for custom DIY projects or any application where a smaller form factor is desired without sacrificing functionality. Highly recommend for its performance and compact design.

Edit: I understand now that to utilize this stepper motor for direct drive, you need at least a 1:3 gear ratio extruder. I purchased a bmg extruder clone and this stepper works wonderfully without skipping any steps. Below is my original uninformed review based on a stock style all metal extruder. I will leave that there for anyone thinking this is a drop in replacement for a non bmg style extruder.Original review:Its a great little stepper motor but I do not recommend it if you're looking to upgrade to direct drive extruder on an Ender 3. I have been playing with it for the past couple days and just cant seem to prevent it from skipping. At 13Ncm it just simply does not have enough torque. Maybe if you drop the speed of your prints down to about 20mm/s or so, it wouldn't skip as much, but that really defeats the purpose of switching to direct drive. I was hoping to fit the smaller/lighter motor to take tension off the x axis, but reading around it sounds like its not as big a deal as i had thought.I will probably just end up converting to the dual z if using the stock motor becomes problematic.All that said, I will keep this little motor around just for future projects. Like i said its great quality, Just not for direct drive.

The packaging, included info card and overall quality of the motor is fantastic. I bought it for use as an extruder for a direct drive system I'm preparing on my CR-10S - the motor works and has very smooth actuation the problem is that its just too weak. It lacks enough torque to drive a dual gear extruder cam and can barely drive a single gear drive (standard) - lots of missing steps (clicking and unable to drive the filament forward) and I found myself helping it along since it did not have enough power to pull the filament off a spool and push it very well. I'm keeping it as a backup but am going to use a stronger motor, I was just hoping to take the weight off the gantry. Also yes I flashed the firmware a few times increasing the power output from my SKR Pro 1.1 / TMC2208 to a little over an amp. The motor even at 900mA gets super hot but was within specifications. This motor is rated up to 80C/176F. 176F will burn you so if it gets a bit hot it's fine. I just don't recommend it as an extruder.

I have a Creality CR-10 that I recently upgraded the print head to a full metal Micro Swiss direct drive system. This upgrade requires moving the existing extruder stepper from the factory bowden system to the print head assembly. It's a great system, but I started getting ghosting and ringing because the print head was so heavy. In order to shave some weight off the head, I opted to buy a much lighter extruder stepper. This one happens to be less than half the weight of the original, and has plenty of torque to pull filament from my dryer box. The weight savings were enough to bring my printer's speed back up to factory standards. The only thing I wish this product had was an option to get one with a connector instead of individual wires. all in all, it was an excellent buy!

This little guy is awesome. Using it on a custom direct feed/drive extruder on a custom build and it works flawlessly. It's more than enough torque and its less than half the size and weight of the standard 64oz stepper I had. The extra weight kept me from making round circles....they always had a slight flat edge that only went away by dropping the speed. This solved everything. One thing to notice is the driver voltage setting. I had all kinds of skipping problems until I realized the motor was running at just over 52c degrees. After adjusting voltage, all was perfect. Wires are a bit short and don't have connectors so you will have to do some splicing/soldering. Comes with a nice little data sheet with specs and diagrams for the tinkerer. Will buy again when the need arises.

The motor works as it should, and I don't have complaints. I have it in a direct drive setup on my Ender 3 Pro with Klipper. In the extruder section of Klipper, I set run_current to 0.5, and I don't have any issues with heat or skipping. It's gets hot but still comfortable enough to keep my fingers touching it.
