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

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.

I have many Nema 23 stepper motors in stock and I know very well how they behave when 4 amps are run through them. This stepper driver doesn't seem to do that. After a while most engines get hot while this driver can only warm up the engine. Its torque also seemed very underpowered, the driver I replaced it with can do the job this one couldn't without skipping steps, all at the same current settings. It looks like someone is lying about their current settings. However, the cost isn't that bad.

The device worked for a Nema 17 motor attached to a screw driver driving a syringe. I didn't need or want much power or speed, so I ran at the lowest current of 12V and 16 microsteps. Silky smooth and quiet. Drawn about 125 mA. I deducted a star due to the lack of documentation and the fact that the activation logic is such that you have to actively manage EN to stop/deactivate it. I've looked at other specimens of this and found paperwork so proceeded cautiously and found that inputs can take…
