Nema 17 Stepper Motor,Quimat Stepper Motor Bipolar 0.4A 36.8oz.in(26Ncm) 34mm Body 4-Lead w/ 0.3m Cable and Connector for 3D Printer/CNC

I bought two for my Anet A6, plug and play no issues or settings to be changed. I've run some test prints and they are indeed quite without any change in quality. Might replace the extruder motor next. Exact same size and appearance as the original. and I actually did a side by side test to make sure I wasn't being duped into buying another motor. They work, they fit on Anet A6 without any rewiring, but I'm entirely convinced they are that much quieter compared to the stock motors. I've been trying everything I could to reduce the printer noise, but I reckon it is at the point where I just have to live with it.

I use NEMA 23 motors in my CNC's, but I needed a motor to test drivers with and this one fits the bill.

I ordered this set to replace a defective TB6600 stepper motor driver that had been running for a long time on my CNC kit. This driver seems a better one, they heightening segment to 32 subdivision, which is suitable foe high segmentation applications. So I will order more in the future to replace my other remaining old drivers.

They run at a higher amperage than most you'll find at this size, but with a TB6600 driver, you're set. I do about 2400 rpm on 1/4 step (36v/7a MeanWell Supply) - perfect for my winding machines.

easy to use, sturdy, very happy with purchase

Correct drivers arrived and once installed worked as expected. Dip switches are sturdy and the documentation printed on top is legible and easy to understand. Best driver for the price. Would buy more of these for future projects. "Used in a Acro Laser From Open Builds"

After trying to get this to work for a couple days, I found that the problem was that the board had shot that caused the EN pin on all the stepper drivers to be set HIGH, thereby disabling the drivers. I checked the arduino pin 8 and it remained LOW at all times but regardless, the GRBL board driver EN pin would show 4.55v at all times. This caused the driver boards to be disabled. Addendum: found out that the arduino close board pin 8 was dead.Considering the other reviews on this board, I have to assume this is not always the case for other people, but, at best you are rolling the dice when you buy this item. I would steer anyone who asked away from this board.EditAfter further investigation, it tiurns ouot that there are two reasons this is was not a good purchase for me. 1) I had planed to use this with GRBL open source CNC software. Turns out that this board is designed to work with an old version (v0.8 and older) of the software. If you download GRBL or use the GRBL arduino library, the version is v0.9 or above. Between version 0.8 and 0.9, the functions of arduiino pin 11 and pin 12 were reversed. This means that the endstops for the z axis will not work with these older boards and current software. Also you will loose PWM control of the spindle.So far, I have not seen an arduino CNC shield on Amazon that I trust would work with GRBL software. Ended up going with Protoneer CNC hat for the raspberry pi.

It's a great driver, the insides were clean and free of manufacturing defects you sometimes get with these kinds of products. The connectors accept 12-24awg and have a rating of 300 volts / 15 amps, the input side of the board was optically isolated so you could run some pretty long signal lines without fear of burning the logic side of the driver out. the only problem I had with it was the two cheap electrolytic capacitors in it but that won't be a problem for years.
