The CNC Shield makes it easy to get your CNC projects up and running in a few hours. It uses opensource firmware on Arduino to control 4 stepper motors using 4 A4988 Stepper drivers,, with this shield and the Arduino you can build all kinds of robotics or CNC projects including CNC routers,laser cutters and even pick&place machines.
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 kept to the top of the stack. Ramps boards are the heart of most DIY 3D printers on the market and a nice clean compact way to integrate all the systems into a compact enclosure mountable format.
The intelligent controller includes an SD card reader, rotary encoders and a 20-character × 4 line LCD display. You can easily connect it to your RAMPS 1.4 board using "smart adapter" included.
This panel connect your RAMPS 1.4, you do not need your computer, your SD card intelligent controller power supply. All further operations, such as calibration, the axis movement can be done only with a rotary encoder intelligent controller. 3D design print without a computer, just use the G code design stored on the SD card.
This Smart Controller contains a SD-Card reader, an rotary encoder and a 128x64 LCD display. You can easy connect it to your Ramps board using the "smart adapter". After connecting this panel to your Ramps you don't need your pc any more, the Smart Controller supplies power for your SD card. Further more, all actions like calibration, axes movements can be done by just using the rotary encoder on the Smart Controller. Print your 3D designs without PC, just with a g-code design stored on the SD card.
Compares to the 2004 Smart LCD Controller With Adapter, this 128x64 screen can display much more information, which would help for you run the 3D printer without a computer.
This breakout board for TI’s 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). It 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 driver has a pinout and interface that are nearly identical to those of A4988 stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications.
The A4988 stepper motor driver carrier is a breakout board for Allegro’s A4988 microstepping bipolar stepper motor driver. The driver features adjustable current limiting, overcurrent and overtemperature protection, and five different microstep resolutions (down to 1/16-step). It 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).
