If you have purchased the unassembled LCD Adapter, the assembly requires some basic soldering. The male headers go on top and female sockets all are below. A video of the assembly can be seen here
- Attach the cables to the LCD Adapter noting the position of the red marking.
- Attach the cables to the GLCD again noting the position of the red marking.
- Attach the LCD Adapter to the RAMBo on the pins labeled: ICSP, SPI, EXT 2.
- In the firmwares Configuration.h file uncomment these lines by removing the from them
Upload the firmware and you should now have a functional GLCD when you power on the printer.If the upload was unsuccessful, and mentions u8glib in the error report, you need to add the u8glib library to your Arduino by following the installation steps here: http://code.google.com/p/u8glib/wiki/u8glib
Format your SD card using FAT16 or FAT32.
To disable the beep on pressing the button on the GLCD edit Rambo_pins.h. Find the section: #define BEEPER and set it to -1
To print from the Graphic LCD, you will need to transfer .gcode print files onto the SD card.
- Create .gcode print files on your computer, in Matter Control click on the Layer View button, and then press “generate”
- When the slicing is done press the “back” button to return to the queue tab.
- Press the “Queue” button and select Export to Folder or Gcode, and save the file to the desired location. Remember where you have saved it, as you will need it for the next step.
- Insert the SD card into your computer using a SD reader slot or USB SD card reader.
- Open a file browser- / -manager and locate the created .gcode files;
drag and drop or paste the .gcode files to the SD card. Once the files have transferred,
eject the SD card from your computer and insert it back into the SD card slot on the the Graphic LCD
The GLCD screen will turn on when you power up the printer. The
start-up screen will display the Status screen, a default screen for the GLCD, presenting the current status of the printer.
There are a number of live statuses shown on the Status screen;
- Hot end temperatures: represents the current temperature (bottom) and set temperature (top) of up to three nozzles.
- Heat bed temperature: represents the current temperature (bottom) and set temperature (top) of the heat bed.
- Fan speed: represents the print cooling fan speed.
- Tool head coordinates: represents the current tool head coordinates on the X, Y, and Z axes.
- Feed rate: represents the current feed rate setting. The feed rate is set to 100% by default; this matches the speed set in the gcode generation.
When on, the status screen selection knob can be turned to increase or decrease the feed rate during the print.
Increasing/decreasing the feed rate will increase/decrease the speed of the print.
- Printer status: lists the current status of the printer including: SD card status, current printing file, or completed print time.
- Current print time: lists the length of time for the current print job.
- Progress bar: represents the progress of the current print job. The print is finished when the bar is completely white.
To navigate through the LCD menu use the selection knob by rotating to scroll through selections and pressing the knob to make a selection.
From the main Status screen, press the knob to move into the menu screen.
To move backwards in the menu tree, select the top most menu selection on the current screen.
Selections that will move you backwards through the menu tree are noted by an upwards-facing arrow.
Note that if the menu is left idle it will automatically move back to the main Status screen.
Before starting a print you will need to set the hot end and heat bed to the appropriate temperatures for the filament type you are using.
To quickly set the printer to preheat, for ABS or PLA filament, click the selection knob to bring up the menu and select .
Select Preheat PLA for PLA filament or Preheat ABS for ABS filament.
This will set the temperatures for the hot end and heat bed and begin bringing the printer up to print-ready temperature.
You can modify the Preheat settings in Control/Temperature/Preheat ABS or PLA Settings.
If you need to set the extrusion and/or bed temperature to a setting different than the preheat temperature you can manually set the temperature.
To do so, from the main menu navigate through: Configuration/Temperature/Nozzle or Bed.
Clicking on either of these settings will give you a menu to set and select the desired temperature setting.
Once the hot end and heat bed have reached the desired temperature the printer is ready to print.
From the main menu select the Print from SD option. You will now see a selection of the directories and .gcode files on the SD card.
Navigate through the menu to locate the file you would like to print. Select the desired file to begin the print.
Making numerous manual movements is easier done using the Matter Control software. However, you can make
manual movements with the GLCD. Navigate to Prepare/Move Axis.
You will select the length of the movement and then which axis to move.
Note; that only 1-mm and 0.1-mm movements are allowed for the Z axis and extruder.
When at the move screen; turn the selection knob clockwise to move the axis in millimeters in the positive direction and counter-clockwise for the negative direction.
Push the selection knob to complete the manual move.
The GLCD allows the tuning of the more advanced configuration settings.
We highly suggest you not modify the configuration settings unless you are certain it is necessary.
To find the configuration settings, navigate to the main menu and then Configuration.
In the configuration settings you will find temperature and motion settings. Among others, these settings include default temperature settings and axis steps per millimeter.
The Store Memory and Load Memory functions will store and load the changes you make using the GLCD Controller.
You must use the Store Memory function to save the adjusted settings when the printer is powered down. The stored settings will then automatically load when the printer is powered on. If you ever need to revert to the factory settings navigate to Configuration/Restore Failsafe. Clicking Restore Failsafe will set all configuration settings back to the original factory settings in the firmware.
