• Special Note: 1.ramps to mega board power supply diode D1 is not soldered, which is the need to separate power supply to the board mega2560, direct usb 5V or through the power connector (official is not recommended more than 12V power supply.) Please understand. Friends also need their own power supply to ramps1.4, otherwise can not be used. 2. The power is reversed, the motor drive board will reverse the chip and circuit may be burned, please confirm again after the power. 1. need to use the module and device: Mega2560 Control Board (Included in this kit): This is the brain of a 3d printer that controls the entire printer to perform specific actions such as printing specific files, RAMPS1.4 (Included in this kit): This is an expansion board for the main board above, which serves as a bridge between the bridge and other hardware for better connection and control. A4988 Stepper Motor Driver Board (Included in this kit): This is used to connect a stepper motor to achieve control of the stepper motor by the main control board for XYZ and extruder operation. 4 to 5 stepper motors (not included with this kit): This is the power part of the 3d printer, controlled by the A4988 drive board, attached to the RAMPS1.4 board; Heater head (not included in this kit): The heater head is used to melt the printed material (ABS.PLA, etc.). Generally, the heater head has two electrical components. One heater can be used to heat the heater after it is powered on. The other is a thermistor, which is used to get the current temperature on the heating head, for better temperature control due to the temperature (Marlin: https://github.com/ErikZalm/Marlin/tree/Marlin_v1) After the success of a lot of operation is allowed, so even if a simple test also need to connect two thermistors (the other is used to get hot bed temperature), Heatbed (not included with this kit): In printing ABS, a common solution to this is to use a hot bed, which also contains two sections, heated in order to keep it immutable and the first layer easy to stick to the platform. Part and thermistor, of which thermistor is required; 12V power supply (not included in this kit): In order to be able to drive the motor and the circuit board, you need to equip yourself with a 12V 100W ~ 200W power supply. The above parts are necessary components of the circuit connection part, if one is missing, will not be able to carry out the corresponding part of the test. Other non-essential include 12V fan and at least 3 limit switches (if not does not affect the test of the circuit board, but will affect the printer's use, if you do a full set of printers, which is necessary, especially the limit switch) . 2. Preparation: You need the necessary software before you start connecting and testing: IDE, the tool used to transfer the firmware to the main control board. Firmware (Marlin) This is the program that needs to be executed on the main control board and is transmitted to the main control board. The transmission method is: Open Ar ** o IDE, Menu Tools -> Board -> Ar ** o Mega 2560, and then select the serial port Tools -> Serial Port -> the corresponding serial port, click compile and download to the board.Refer to the firmware inside the instructions to configure the corresponding parameters, the most important is Configure the board type RAMPS1.4 (Find this line in Configuration.h file # Define MOTHERBOARD 33 [must be changed to 33]), the other can be temporary default; the corresponding version and install; The above is the software you need to use, the first one is that you often need to configure the parameters, if the parameters are determined, it is rarely used again, the third is the printer control software, usually print will be used. 3. Burning firmware: Edit the firmware and upload it to the dashboard: Connect the main control board to the computer via USB. The power LED of the main control board will be on. Use Ar ** o IDE to open the main file (Marlin.pde) in the downloaded firmware file, open it, select the Configuration.h file via TAB, and find: # ifndef MOTHERBOARD #define MOTHERBOARD A number #endif change into: # ifndef MOTHERBOARD #define MOTHERBOARD 33 #endif Temporarily modify these parameters. Then select the menu Tools -> Board -> Mega 2560, and select Serial Tools -> Serial Port -> the corresponding serial port (usually the penultimate one, you can not try a few more times) Click on the right arrow (→) icon on the IDE, the firmware upload, if you install the above steps should be error-free. And you can see the other LED on the main control board will keep flashing, indicating that the upload In; waiting to be completed. 4. Connect other circuit boards and test: Disconnect the USB data cable, the RAMPS1.4 board connected to the master class, be careful not to connect errors, RAMPS on the back of the pin should be connected to the main board only then.And then connect the two thermistors to the board accordingly Position, the first figure, then open printrun software (the third software above), select the serial port (usually the last one), set the baud rate (250000). Click the connection if normal, there will be a connection to the right Prompt text, and the following operation button will be able to work properly. The temperature of the two thermistors can be obtained by the "check temp" (read temperature) on the printrun software. Because the thermistor is connected directly, the reading temperature should be close to your room temperature and if read The value is 0, all connections are incorrect, please check. Although the heating head and the hot bed are not connected, a simple test can be carried out. Firstly, a 12V power source is connected, and then the temperature of the heated bed and the heating head are respectively 230 and 110 degrees. At this moment, two red LEDs on the board are lit successively, This shows that this part of the circuit is normal, turn off then enter the command and then lower right corner: M106 S255 point to send to open the fan control, then another red LED will light, enter: M107 point to send can be turned off. Disconnect the power supply and connect the A4988 driver board to the RAMPS board, pay attention to the correct direction, otherwise it may burn out the board, please refer to my picture.At least one motor should be tested and the motor connection should be as shown below Connect, the general order of red, blue, green and yellow connection, connect, turn on the power, through the printrun can try to move the motor, for example, you connect the motor to the X axis, the motor X axis motor +10 mm, Rotate, click - 10mm, the motor will reverse. The same can be tested YZ two axis (change the motor should be cut off the power.) Extruder motor when the temperature is not reached can not be tested, you can install its A4988 drive XY or Z axis test to ensure the normal drive. If the above test is no problem, indicating that the main circuit there is no problem, and the rest is to your 3D printer assembly up.
