new SunRobotics CNC 3D Printer Kit with Mega 2560 Board, RAMPS 1.4,DRV8825,LCD 12864,Heat bed MK2b for Arduino DIY GRBL/Prusa 3D Printer

The Adriuno MEGA 2560 is designed for projects that require more I/O lines, more sketch memory and more RAM. With 54 digital I/O pins, 16 analog inputs and a larger space for your sketch MEGA 2560 is the recommended board for 3D printers and robotics projects.The RAMPS (RepRap Adriuno Mega Shield) is an all-in-one design to fit the necessary components for a 3D printer into one plug in shield for an Adriuno MEGA.The driver features adjustable current limiting, overcurrent and over-temperature protection, and five different microstep resolutions (down to 1/16-step). RAMPS operates from 8 – 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling).DRV8825 microstepping bipolar stepper motor driver features adjustable current limiting, over-current and over-temperature protection, and six microstep resolutions (down to 1/32-step). DRV8825 operates from 8.2 V to 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).The PCB heat bed is a great addition to your 3D printer to help your printing platform to be a heated surface perfect for minimizing warping of larger prints.
