TwotreesTB6600 Stepper Motor Driver 4A 9-42V CNC Controller for 42 57 86 Stepper Motor Nema17 Single Axes Phase Hybrid Stepper Motor for CNC Arduino 3D Printer (3PCS)

HAD 3 OF THESE BAD BOY'S EXPLODE ON ME! HOWEVER I WAS PUSHING SOME REAL POWER TO THEM.36 VDC ON SOME NEMA 34 1800 OZ MOTORS. THEY RAN FINE FOR ABOUT 5 MIN. THE KAPOW! DRIVER ACTUALLY POPPED. LEAVING A BOUNTYFUL CLOUD OF ODIFFEROUS IMMINATIONS OF OZONE LINGERING AROUND MY SHOP.THEY WORK GREAT ON THE SMALLER MOTORS THO.USE YOUR OWN JUDGEMENT.

I used three of these to run an XY table for PCB drilling, driven by a Raspberry Pi Zero. They make interfacing to steppers much easier than building your own. The instructions on use can be a little confusing, but as far as I can tell, if you wire it wrong or put the switches to an invalid setting, there is no damage. And it is easy to find help online for settings and use.The picture is the prototype kluge that I built to design the system. Its first use is to make a PC board to make interface Mark 2, which will be much cleaner and without the scrambled wire nest. The three drivers are the devices with the green connector blocks.Recommended

Copy or not, these should not be advertised as a TB660.

Tried the grbl sheild for Arduino motor drivers and had problems. Printed my own pcb and connected these and work great. Easy to set the current and stepping. Work recommend every time. Used on my cnc I built.

As expected, 100% working unit. Easy to setup.
