You cant use d0 or d1 on aux-1 these are also known as tx0/rx0 ie is connected to the serial/usb converter

move the connectors down one row and use D57/D58

Other than that it looks ok...

You dont need the two jumpers connecting a-step to D12 and a-dir to D13 since you have nothing plugged into those IO pins
