I have 3 tb6600 stepper drivers to wire up to some nema 23 motors(2.3V at 2.8A, inductance of 2.2mH)and basically I have no idea about how to connect anything. I was watching This Old Tony and he mentioned using 1/3 or 2/3 of the rated amperage(through the driver) for the motor to run properly. This entire time I assumed that I would be setting the driver at the 2.8 amps that the motor is rated for, but now I'm all messed up for wiring. Anybody out there who could explain this to me?
