STEPPERONLINENema 17 Stepper Motor 2A 55Ncm Bipolar 1.8 Degree 4-Lead for 3D Printer CNC Extruder, 5 Pack

The media could not be loaded. Overall I am very pleased with this stepper, it’s more than strong enough to power through my filaments at whatever speed I want.I attached an aftermarket heat sink to all of my steppers but I have to say this one runs much cooler than the others.The pricing is very competitive and it was worth every penny.All in all, good torque, great performance, much lighter than the stepper I had before, perfectly suited my needs

I purchased a set of three Nema 17-48mm motors (the larger size) for my homebrew printer.My printer is fairly large, and so initially I wanted to use these on the X and Y axis... for yucks sake, I installed it on the head for a direct extrusion setup. While the 48mm motor was HUGE for the direct extrusion and an overkill, it did a good job there. Eventually though I moved the 48mm motors to the X and Y axis. I wanted to also use it for my Z axis but the 48mm motor proved a little too tall for the way my X axis arm bracket was setup so I skipped it.Now to the motor itself:Quality: they appear to be commodity (in other words, I've seen different brands that look identical to these), but they're clean, nicely machined and they work.Application: I used them in my 12V setup, using up to 1A of power. All appears to have functioned well and there is no layer skipping.Thermals: At 1A drive+0.7A hold, the motor did get noticeably warm. When I lowered the hold power to 0.5A this seems to have dissipated.Anyways... I use them... the price was good... and they're running like a champ. Safe buy!

It's a decent stepper. I used this to help troubleshoot an issue I was having with Y axis on S5 Printer. This shared the same pin and direction as stock motor. So, no need to change direction in firmware. This motor did the same thing as existing motor, so I increased current to this motor in Marlin firmware on SKR control board. It works great. I recommend it. Should replace any stepper in typical Creality CR-10 style printer, and likely more. Certainly can be used in many more printers. Just make sure the length of this housing will fit in the location you are thinking of installing it.

I did not check the motor and my return window lapsed until I figured out it was not working right. The seller promptly reached out and made it right. For that (peace of mind) I’m giving it 4 stars. The other motor I bought from them (admittedly it’s a different model) works fine.

Reduces Direct Drive weight (over attaching the original Creality extruder motor) and has plenty of torque to correctly extrude filament.Note that you'll have to adjust (to your satisfaction) motor current if this is a different motor than what you're replacing (as in: lightening the motor used for a direct drive, as I have).

I bought this a number of weeks ago in the process of designing a new extruder for my kit bashed Prusa MK2 - I call it my ORIGINAL i3 Custom...based on the Titan Aero extruder with E3D V6 HotEnd. After changing out my toolhead and re-connecting everything when it came time to extrude the motor buzzed, but no rotary motion. I noticed a reviewer pointed this out, and the product image collection shows this. A simple correction (in my case swapping the 2 middle pins), resulted in extruder motion.Other than that I have nothing but good things to say about it. It replaced a motor that was (unnecessarily), twice its size, reducing the weight my all metal carriage has to move in X. The motor has plenty of torque to drive the Titan Aero with 1.75mm filament (I have yet to test with a fiber-reinforced PLA, but with regular Hatchbox PLA it works great. I expect similar results with Hatchbox PPLA and PLA Pro+. Motor worked right out of the box without issues other than that caused by an mis-wired cable. During the heat of a 1-2 hour print job, checking motor temp with a touchless infrared thermometer, the motor temp didn't go above 38C (that's a couple degrees above normal body temperature for comparison), while my Z motors run around 28, X about 28, Y about 30.Pic is of the top view of the toolhead. The pancake motor is clamped to the carriage to the bracket just behind the extruder. Room was left between the stepper and the vertical plate of the carriage in case the motor change needed to be backed out.I would highly recommend this motor.

It did everything a stepper motor should, including having a removable cable. Very good!

Spec wise this is prefect. It has enough torque to work and is lighter and more compact than the 42-34 Micro Swiss recommends to use. But it will not work unless you are willing to take a file to the shaft and extend the flat surface towards the stepper.If you unscrew the grub screw enough you can fit the drive gear onto the shaft and even tighten it enough to hold on the round shaft. Since the grub screw is sticking out a very small amount it catches on the lever. It might wear a groove in it so it can be used but I did not want to take a chance on damaging something. So I took a file to the shaft and extended the flat part.Now it fits perfectly and so far is working as good as the larger and heavier recommended 42-34 and original 42-40.

Well packaged and comes with a card outlining the motor specifications. Drop-in upgrade/replacement for the X and Y-axis motors on my SV06+.

Moteur pas à pas nickel. Fonctionne parfaitement pour mon projet !

Sehr gute Schrittmotoren die für ein kommerzielles Automatisierungsprojekt verwendet werden.Der europäische Lieferant wollte das fünffache pro Motor!

Como esperado

Acquistato per sostituirlo al motore 42-40 dell'estrusore della mia Ender3 2018 ora modificato in direct, sostituito senza problemi, silenzioso e performante.Penso di acquistarne altri per i miei progetti.
