Review on 🏎️ Enhanced Performance TB6600 Stepper Driver Controller: Unleash Your Stepper Motor's Full Potential by Adam Rogers

I bought two of these for my CNC router. Both worked day and night. Now one fails regularly. Each drives a 3A stepper motor. One of the controllers just turns itself off after a few minutes of operation, the light goes out. If I restart the 24V supply it works again. There is no overheating, but something on the board may not be right.
