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

This stepper motor works fine. I bought it for a laser engraver upgrade. An adjustable Z axis and I thought the stream thin profile would be an advantage. So far, so good. The motor appears to be good quality and well built. The small size does limit the torque, so be sure the motor is suitable for your application before purchasing.

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.

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.

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.

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!

I am using this with my printer running bmg wind extruder. I am driving this off of a skr 1.4 turbo with tmc 2209 drivers in spread cycle mode. I have seen a lot of comments with over heating, that is most likely because ppl are overdriving it, I am running this at 0.4A run current and 0.36A hold current and never had issues with extruder slipping or missing steps. Firmwares like Marlin and Klipper use RMS current in configs rather than peek current and if you are running at 0.75A rms current then that equates to 1A peek. So if you are running marlin or klipper run it at or below 0.5A
