3pcs iMetrx Nema 17 Stepper Motor 42x34mm 1.5A-3.8V 2 phase 4 wires 1.8 degrees with 1Meter cable for 3D Printer Motors

good motor

The media could not be loaded. Incredible, I replaced the X and Y motors of my Ender 3 Pro with 42-40 ones of this and I was able to increase the acceleration from the default 500 m/s2 to 5000 mm/s2, and probably can go higher with a little more voltage, but I'm quite happy with the current speed, with the input shaper and the linear advance features of Marlin, now the printer prints 2.5-3 times faster with higher quality. Though the top speed is still limited with 120 m/s as the hot end can only melt around 12-12.5 mm3/s of filament. The model in the video normally prints in 12-13 hours, I was able to complete it in 5 hours, unbelievable... I increased the default voltage from 580 mV to 850 mV and that's it. The original motors, especially the X motor was getting too hot, around 50 °C, even with an acceleration of 1000 m/s2 and the aforementioned 580 mV input voltage. The new ones never go over 30 °C. I'm super happy and planning to buy another 5 of these to replace the Z axis and my MMU2s motors. Oh, I didn't need to change my printer cables, these were a drop-in replacement, my board is an SKR 3 EZ.

Put this on my ender 3 pro’s extruder as I upgraded to dual gear, really nice quality and i would probably buy a couple should i need them,

Spot on

I was surprised by how quite these stepper were using a4988 motor drivers they don't sing like my other steppers.

My 42-34 X axis stepper motor would get to hot to touch, when doing a big print, due to my dual drive bowden extruder adding more weight.After fitting the 42-40 motor, the movement is a lot smother and the motor never gets hot.Very pleased with it and would recommend.

I use these motors for telescope autofocusers. They're perfect for the job - hi torque and stay quite cool during use.

Good price quick delivery works as required

Great Ender motor replacements seem well built. Will see if these last longer than the original motor.

Moteur pas a pas pour ma cr10 s5 remplace l ancien qui avait un aimant fendu

Hat die Erwartungen erfüllt !

Nema Motoren sind bekannt für ihre guten Eigenschaften ich bin zufrieden damit.

Hace perfectamente su trabajo como motor del eje Y.Ya lo tengo varios días trabajando y todo va perfecto
