I purchased 2 of these for my Ender 3 pro. One on the Y axis and one on a belted Z axis. Both of them operate without any issue. I am running them at 1.4 amps RMS and they do warm up but not anymore than the factory steppers. I will be purchasing more when my Ender 3 Max arrives.

I gots the Flsun super racer and the manufacturer used the cheapest possible crap they could to make that printer which created a ton of trouble due to a stupidly thin washer getting sucked straight into the motor. Enter these motors to save the day. Printer now works thanks to these fabulous motors. â¤ï¸

Used on Voron Afterburner. Working well.

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.

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.

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).

Great stepper, made my extruder work perfectly finally. Had trouble with the e3d stepper I bought, had to run it at high amperage to get it to function and it still skipped steps all the time. Replaced it with this and I haven’t had a problem since. Light powerful and quiet, can’t go wrong with this one.

Het verbaasd mij enorm hoe veel herrie deze motoren maken. Ik dacht dat ze stiller waren maar ik kan dit niet gebruiken voor mijn project. Ik ben over gestapt naar stille servo's.

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.
