The modular design includes plug in stepper drivers and extruder control electronics on an Ard MEGA shield for easy service, part replacement, upgrade-ability and expansion.
Additionally, a number of Ard expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack.
