RAMPS 1.4 Reprap 3D Printer Arduino Mega Shield Arduino Nano Order the default Arduino PortentaIntroduction : The RAMPS (RepRap Arduino Mega Shield) is an all in one design to fit the necessary components for a 3D printer into one plug in shield for an Arduino MEGA. The plug in shield design includes plug in stepper drivers and extruder control electronics sockets for easy service, part replacement, upgrade ability and expansion. Additionally, a number of Arduino expansion boards can be added to the system as long as the main RAMPS board is
