First connect your computer with a standard USB cable. The power LED should
light up and the blue debug LED should blink once. The rxd and txd LEDs near
the USB connector may blink fast for a short period.
Connect the stepper drivers to the designated connectors. You can connect up to
5 stepper motors, 1 for each axis, except for the Z-axis, which allows two stepper
motors to be connected. Also an external stepper driver is supported, check the
datasheet for more details. You can use the following order of colors, but if you
reverse the connector, the stepper motor will just reverse.
