Alternatively, the RepRap Arduino-compatible MEGA Pololu Shield, also known as RAMPS, is a compact and cost-effective solution that integrates all the electronics required for a RepRap machine. RAMPS connects an Arduino Mega board to the powerful Arduino MEGA platform and provides ample space for expansion. The modular design includes plug-in stepper drivers and extruder control electronics on an Arduino Mega shield for easy maintenance, part replacement, upgradeability, and growth opportunities. Additionally, a number of Arduino expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack.
