    If your motors are running hot than the currant is too high. Set it lower as per the table printed on the driver. Start with 1.7A and if it doesn't drive the two motors you can increase it.
    As for the wiring, google the tb6600 and lots of wiring diagrams will come up. You also can look at the wiring that you already have!

    Hello
    Usually you have two drivers , one for each motor and in your motion controller the two are paired together so that the two motors work in tandem.
    Not sure why they wired two stepper motors to one Driver.
