2. SCHEMATIC DRAWING
First you have to connect the Arduino MEGA with the Ramps 1.4 expansion
board. Plug the board on the Arduino that way that the pins on the
bottomside of the boards are connected in accordance with the ports of
the Arduino.
The following schematic drawing shows the detailed pin assignment.

4. JUMPER-CONFIGURATION
Before you can plug the necessary stepper motors on the expansion board,
you must set the particular jumper first. The jumpers define the amount
of possiblie microsteps for the stepper motors. It can support up to 1/128
steps. The exact configuration is additionally dependent of the utilised
stepper motor drivers.
