STEPPERONLINENema 17 Stepper Motor 1.8 deg 16Ncm 1A 4-lead for DIY CNC 3D Printer

Running this on an both an Afterburner and Stealthburner conversion for my Ender 3 printers.Love it. runs warm without missing steps, plenty of torque.

Used this for the skelestruder on my PRUSA MK3, just had to set the current down to 300mA. Works very well, but you will need to extend the wiring as what is attached is not long enough to run from the extruder head to the control board.This is the only negative thing I can say about this, and this was due to my application. Shame they don't do this particular model with a plug socket design.

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.

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

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.

Like light weight, low price, small size, good performanceDislike motor is 20.7mm thick not 20mm thick as the drawing shows.I used this motor on a custom Pitan extruder design. I remixed the original Pitan to fit the ender 3. I had to re-edit my design because the motor I received was 0.7mm thicker than the drawing shown on Amazon. So that made me mad.Other than the dimension issue the motor is fine. I use a 3:1 gear ratio on the extruder and 0.725A current to drive the motor. I used the hobbGobblin drive gear in the filament path. I needed to reverse the Green and Black wires to make the rotation direction correct for the Pitan.I would ask the seller to update the drawing to show the actual thickness.

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!
