Ramps 1.6 with Display & 5x A4988 Motor Driver

GENERAL INFORMATION

Dear customer,
thank you for choosing our product. In the following, we will show you how to use your product.
Should you encounter any unexpected problems during use, please do not hesitate to contact us.
With this set you lay the foundation for the installation of your own 3D printer on the basis of Arduino.
Not only the required stepper motor output stages are included, but the board also offers connections for up to 3 heating units (printing bed heating, extruder 1, extruder 2) with each 3 possible inputs for connecting the required temperature sensors. In addition, fans for component and extruder cooling can also be connected.
With the matching, installed software on the Arduino MEGA, it can show you the current status or rather information like temperature on the included LCD- display.
Compared to its predecessor (RAMPS 1.4), the MOSFET‘s and screw terminals of the RAMPS 1.6 have been adapted for  higher power consumption.  In addition, the thermal design has been revised to generate better heat  dissipation.
SCHEMATIC DRAWING
The following schematic drawing shows the detailed pin assignment. CONNECTION TO ARDUINO MEGA
First you have to connect the Arduino MEGA with the Ramps 1.6 expansion board. Plug the board on the Arduino so that the pins on the bottom of the boards are connected in accordance with the ports of the Arduino.
JUMPER-CONFIGURATION
Before you can plug the necessary stepper motors on the expansion board, you must set the corresponding jumper first. The jumpers define the amount of possible micro steps for the stepper motors. It can support up to 1/128 steps. The exact configuration is additionally dependent of the utilized stepper motor drivers.The different jumper slots are shown in the picture above and in the schematic drawing before. The various step configurations are displayed in the following chart.

STEPPER MOTOR DRIVER After the jumpers are set, the stepper motor drivers have to be plugged into the black slots which are directly at the jumper slots. Make sure that the stepper motor driver are rightfully plugged in. You can gather the information from the following picture on how to plug in the motor drivers correctly.
If you have successfully inserted the motor drivers, you can connect the stepper motors. CONNECTIONS
Now the end stops and the temperature sensors can be connected. Up to 6 end stops and 3 temperature sensors can be connected. You can see here the typical connection of the end stops. The temperature sensors get the connector T0 for the HotEnd and the connector T1 for the heat bed. The polarity of the temperature sensors are not relevant.
Additionally, the heatbed must be connected to the connector D8 and the HotEnd to the connector D10. D9 can be used for a fan or for an additional HotEnd. You can also now plug in the display into the provided slot.
Lastly, the expansion board only needs power to go into operation.

INSTALLATION OF DEVELOPMENT ENVIRONMENT

For the application is a development environment as well as the Marlin 3D firmware needed.
For that you first have to download the Visual Studio Code software from their website and install it.
Afterwards download the Marlin firmware here.
Open Visual Studio Code and click Extensions on the left. Now type Platformio in the search bar and install the PlatformIO IDE.Now you can open your previously downloaded Marlin firmware folder under File -> Open Folder and adjust the Configuration.h file.
CONFIGURATION OF THE SOFTWARE
Board selection
Before the software can be transmitted to the Arduino, the used configuration must be adjusted.
The most common configuration consists of one HotEnd, one fan and one bed. Depending to its purpose and structure the configuration can be differed. In accordance with the configuration, the motherboard in the Configuration.h file must be registered.
Open the Configuration.h file and search for the corresponding definition of the motherboard. You can quickly search for the corresponding line by pressing STR + F.
For the earlier mentioned configuration (HotEnd, fan, bed), the motherboard configuration should look like the following example:
// Choose the name from boards.h that matches your setup

ifndef MOTHERBOARD

define MOTHERBOARD BOARD_RAMPS_14_EFB

endif

Other configurations can be set by replacing the Other configurations can be set by replacing the BOARD_RAMPS_14_EFB variable. Therefore, the following table applies.
variable. Therefore, the following table applies.

Display
To activate the display, an additional configuration needs to be performed. Therefore, in the Configuration.h file, search for the following section:
// RepRapDiscount FULL GRAPHIC Smart Controller
// https://reprap.org/wiki/RepRapDiscount_Full_Graphic_Smart_Controller
//
//#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
To activate the display, delete the commentary lines in the last line so that it looks like that:

define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

If you have problems with the image on your display, you can fix this by changing the timings. To do this, insert the following lines:

define ST7920_DELAY_1 DELAY_NS(0)

define ST7920_DELAY_2 DELAY_NS(400)

define ST7920_DELAY_3 DELAY_NS(0)

Amount of extruders
If you use more than one extruder then you also need to adjust the following line in the Configuration.h file appropriately:
// This defines the number of extruders

define EXTRUDERS 3

Temperature sensors
Also the configuration of the temperature sensors must be adjusted in accordance with the used sensors.
Note the configuration notes in the following section of the Configuration.h file:

define TEMP_SENSOR_0 1| #define TEMP_SENSOR_3 0

---|---

define TEMP_SENSOR_1 0| #define TEMP_SENSOR_4 0

define TEMP_SENSOR_2 0| #define TEMP_SENSOR_BED 0

Even the maximal permitted temperatures can deviate in accordance to the used components. Because of that, you should match the maximal temperatures with your components in the following section:
// If temperature exceeds max temp, your heater will be switched off.
// This feature exists to protect your hotend from overheating accidentally, but NOT from thermistor short/failure!
// You should us MINTEMP for thermistor short/failure protection.

define HEATER_0_MAXTEMP 275| #define HEATER_3_MAXTEMP 275

---|---

define HEATER_1_MAXTEMP 275| #define HEATER_4_MAXTEMP 275

define HEATER_2_MAXTEMP 275| #define BED_MAXTEMP 150

Direction of rotation of the stepper motors
In accordance with the wiring or polarity of the used stepper motors, it can be necessary to invert the direction of rotation of individual motors.
This is possible in the following section:
// Invert the stepper direction. Change (or reverse the motor connector)if an axis goes the wrong way.

define INVERT_X_DIR false

define INVERT_Y_DIR true

define INVERT_Z_DIR false

// Enable this option for Toshiba stepper drivers
//#define CONFIG_STEPPERS_TOSHIBA
// @section extruder
//For direct drive extruder v9 set to true, for geares extruder set to false.

define INVERT_E0_DIR false| #define INVERT_E3_DIR false

---|---

define INVERT_E1_DIR false| #define INVERT_E4_DIR false

define INVERT_E2_DIR false|

When you have made all settings, you can transfer the program to your Arduino by clicking on PlatformIO: Upload in the bottom left corner.
