Cable length: 300 mm
Packing way: cartion package
1 Necessary modules and components:
Arduino Mega2560 control board (included): responsible for controlling the entire printer to complete certain actions
RAMPS1.4 (included): better to connect and control other hardware and control.
A4988 stepper motor driver board (included): used to connect the stepper motor control board in order to achieve control of the stepper motor and XYZ and extruder action;
4 to 5 stepper motors (NOT included): the dynamic part of the 3d printer controlled by the A4988 driver board, the motor is connected to the RAMPS1.4 board;
Heating head (not included): melt the printing materials (ABS, PLA, etc.), there are generally two electrical heating element head: one is heating wire that can be heated when it is energized and the other is thermistor that can be used to achieve better temperature control by getting the current temperature on the heating head, in order to achieve better temperature control.
Heatbed: (not included):it contains two parts, the heating section and a thermistor. The thermistor is required;
12V power supply (not included): In order to be able to drive the motor and circuit board, you need 12V 100W ~ 200W power.
These parts are essential component parts of the circuit connection. If a short of any one will not be able to test the appropriate section.
2 Preparation:
Before you begin connecting and testing, you need some necessary software:
Arduino IDE, transfer the firmware to the tool on the control board
Transmission method: Open arduino IDE, select the menu Tools -> Board -> Arduino Mega 2560, and then select the serial Tools -> Serial Port -> corresponding serial port, click compiled and download to the board.
