After I fried my Chinese TB6560 board, I decided to move on to installing Gecko 251X drivers. I still had the little blue manual control that came with the TB6560 board that was very convenient for moving the axis manually. I am also using it to test the new drivers. My main problem has been interfacing the MO-CON501 pendant controller with a driver. With help from people on the "How I fixed my Chinese TB6560 board" thread, especially Doorknob, I am continuing to come up with a plan for this. Right now continuing to check out interface board per Doorknob's instructions. I already found that the step pulses coming out are only about 1v amplitude despite the 5v supply voltage. This wouldn't step the TB660 board and probably not the Geckos either.
