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?
