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

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.

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.

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

Exactly what I needed. Arrived quickly and efficiently! Thanks!

Ready to setup. Works great!

For most small stepper motor applications (like 3d printing), this driver would be overkill. The little “step-stick” style pc-mount drivers are fine in those applications. But every so often, you need 3+ amps of drive current for thinks like cnc cutters or machine retrofits. This unit is great for those requirements. The “32 subdivision” reference is to microstepping - a technique that divides a step cycle into more parts. In practice, this should not be thought of as a way to increase resolution, but rather to increase smoothness and reduce resonance problems. Other drivers offer as much as 256 levels of microstepping, but the practical value of that specification is debatable. This driver does the job when you need to step up to just a bit more power.

The stepper motor controller worked during testing. As soon as I put a load on the motor, it burned out after a few cycles. I replaced it with a controller that had overvoltage protection and overvoltage was rated 50% higher.

Wiring diagram was not included in the package, only the controller, so be sure you get the information off of the product page, or other online sources. I tested this on a small NEMA 17 motor, 1A, and controlled it from an Arduino. Had fun seeing what all of the micro-step settings did. Heat sink did not get warm at all from this light load. The inputs are LED optocouplers (8-15mA), and since both anode and cathode connections are exposed, you can treat these inputs as active-low, or active-high, with your own wiring. One thing that's not obvious--with ENA unconnected (off), power is maintained to the motor windings continually to hold its position, and when you do assert the ENA (on), the motor can free-wheel.
