EASON Stepper Motor Driver TB6600 4A DC9-42V 32 Subdivision for Nema 17, 23 Series Stepper Motor CNC Controller Single Axis Hybrid MicroStepping

What can i say, but this 6600, is reliable and well done all around.

Worked way better than the transistor setup I was using to drive a stepper before. Just so you know, there's ZERO documentation in the box- you just get the device and not a single scrap of paper comes with it. Use the documentation on this page AND note that for the dip switches the ON direction is down. Only thing they were really missing was how long you need to make the pulse on the pulse pins, or how much time you need on the enable or direction pins before the changes take effect. I used 30 microseconds on the pulse pins and it doesn't seem to miss any steps. Maybe less is fine, but that worked for me and I didn't need it to be faster so I left it at that.

This works very well. Pay close attention to the manual as it is important to get all the inputs correct to get the system to work. The connections are robust and easy to use. The system works very well and does not get hot even while driving a motor with the maximum current allowed.

Works well, and good documentation out there. Got ahold of it and working within an hour.

Beware. The listing says "Suitable for drive Two-phase stepping motor dynamic voltage 9V to 42V, the maximum drive current is less than 4A." And, on the case it has all sorts of settings leading up to about 4A. What a joke. The most these drivers produce is about 1A. I have 3 of them, they are all the same. If you are pushing around a laser or maybe a 3D printer they will probably work. But forget using them on any type of mill/router. They sort of work. Very, very limited. After replacing them with a much better brand, my machine now runs about 3X times faster in cuts. Imagine that! as the saying goes "the cheap quality remains long after the low price is forgotten"
