Joy-it Ramps 1.4 with Display & 5x A4988 Motor Driver User Manual

Joy-it Ramps 1.4 with Display & 5x A4988 Motor Driver User Manual

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.

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 1.4 expansion board. Plug the board on the Arduino so that the pi s 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 possiblie microsteps 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.

ENDSTOPS AND TEMPERATURE SENSORS

Now the endstops and the temperature sensores can be connected. Up to 6 endstops and 3 temperature sensors can be connected. You can see here the typical connection of the endstops. 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.

POWER SUPPLY AND DISPLAY

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. For the Ramps 1.4 board is the following configuration intended:

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 configuartion should look like the following example:

Display
To activate the display, an additional configuration needs to be performed.
Therefore, in the Configuration.h file, search for the following section:

To activate the display, delete the commentary lines in the last line so that it
looks like that:

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:

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:

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:

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:

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