Stepper Motor Controller Problem Answered

I recently set up an Arduino Uno, stepper controller, stepper motor, and power supply. Connected the motor to a shaft on a device I`m making and was able to turn the shaft as I wanted.

The controller was a TB6600 that I borrowed from a friend. Received 3 new controllers from Ebay and swapped the new one for the borrowed one. Tried all 3 controllers and none worked.

Any ideas on what`s wrong or should I just return them and buy 3 more from someone else?

How sure are you at wiring colors etc..
Ask your friend..

His TB6600 worked fine. Mine had the same labels, so we just unplugged from his and plugged into mine. Is there something else I need to do? Didn`t get any documentation with the controllers to help.

The conclusion is there is bad electronics being sold.
As a last try I would put some pressure on the seller..
He knows what to do or get a bad rating.

BTW I'm an experienced EE and you are doing everything correct..
However I never buy with out a full manual !
And if the cost is low, I would take a controller apart looking for loose wires.

A nice PS that I bought had a crappy wiring but three bad controllers is pushing credulity..
