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

Great product. I've conducted multiple tests with these steppers and they work well with the motor drivers I purchased and have some very long cables which will be immensely useful for my project. These arrived in a well packaged box and will purchase from here again when I need more.

Bought these to use with a 4:1 pulley for some moderately heavy Venetian blinds. Only gripe is that without idle hold enabled, then still turn when under load.

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.

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

These are not 1.5A. They trip out at anything over 600mA
