3D Printer Dashboard Kit ( 2560R3 Main Control Board + 3D 1.4 + 4988 Driver)<br />RAMPS1.4 3D printer control panel size: 115 * 60mm<br />Arduino2560R3 Development Board Size: 102 * 54mm<br />Stepper motor drive A4988 Size: 20 * 15mm<br />USB cable length: about 500mm<br /><br />1. The modules and components needed:<br /><br />Arduino Mega2560 MPU (The kit contains): This is a 3d printer's brain responsible for controlling the entire printer to perform certain actions， such as printing specific documents;<br />RAMPS1.4 (The kit contains): This is the main control board of above t expansion board， with it can better connect with other hardware and control， functions as a transition bridge;<br />A4988 stepper motor driver board (The kit contains): This is used to connect the stepper motor control board， in order to control the stepper motor， to achieve XYZ and extruder action;<br />4 to 5 stepper motors (The kit not included): This is the power part of the 3d printer， controled by the A4988 drive board， the motor is connected to the RAMPS1.4 board;<br /><br />Heating head (the kit not included): heated head is used to melt print materials (ABS， PLA， etc.)， the general thermal head has two electrical components<br /><br />Hot Bed (heatbed) (This kit is not included): When printing ABS， to let invariance and the first layer easily stick to the platform， the general solution is to use hot bed. Hot bed also contains two parts， heating parts and the thermistor， wherein the thermistor is required;<br /><br />12V power supply (The kit not included): In order to drive the motor and circuit board， you need a power of 12V 100W ~ 200W or so.<br /><br />Above parts are essential component parts of the circuit connection， if lack anyone of these， you will could not test corresponding portion.<br /><br />Other non-essential include 12V fan and at least three limit switches.<br /><br />3D 1.4 Dashboard * 1<br />Stepper motor drive A4988 * 5 个<br />2560r3 development board * 1<br />USB cable * 1<br />Static bag & carton packaging<br /><img src="http://img6.eachbuyer.com/x9/p100/eb4325_1.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/eb4325_2.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/eb4325_3.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/eb4325_4.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/eb4325_5.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/eb4325_6.jpg" />                                                        <img src="http://img6.eachbuyer.com/x9/p100/eb4325_7.jpg" />
