Abstract
Indiegogo campaign RepRap Graphic LCD Controller with Fan Output
This is an easy to use expansion board for the popular Sanguinololu, Melzi & RAMPS electronics. It adds the most of the available addons for the Sanguinololu/Melzi/RAMPS in one board.
Details
The Controller features
- Automatically controlled stepper driver cooling-fan output
- Hotend fan control (importatant for PLA printing)
- Stand alone printing from micro-SD card
- 128x64 dots graphic LCD display
- Beeper
- Plug and Play installation
Simply plug the adapter to the Sanguinololu expansion connector and connect the controller board with the included ribbon cable.
Available LCD Colors
Easy user interface
Status screen with animated icons. These icons give a quick overview of the status of the printer. It shows an animated fan icon, when the hotend fan is operating. Heating of the hotends and the heatbed is indicated with small dots inside the icons. Printing progress and the actual extruder position on the bed is displayed via progress bar / coordinates. Communication with the user via a nice graphical user interface which allows to set most of the relevant parameters by turning and clicking the menu-wheel.

Required firmware
To make use of the graphics LCD, Erik Zalm's Marlin is recommendet. It can be downloaded from GitHub (https://github.com/ErikZalm/Marlin), all other functions are compatible with most of the other firmwares for the Sanguinololu.
Others
All pictures show the prototype design. The final design comes with a totally black PCB and micro SD-connector. On Melzi the fan switch output is disabled because Melzi has an on board fan switch output.
RAMPS Adapter
A RAMPS adapter will also supplied.
