Full Graphic Smart Controller

Based on bkubicek idea and STB's DOGM128 implementation, we realized this full graphic smart controller.


This full graphic Smart Controller contains a SD-Card reader, an rotary encoder and a 128 x 64 dot matrix LCD display. You can easy connect it to your Ramps board using the "smart adapter" included.

After connecting this panel to your Ramps you don't need your pc any more, the Smart Controller supplies power for your SD card. Further more all actions like calibration, axes movements can be done by just using the rotary encoder on the Smart Controller. Print your 3D designs without PC, just with a g-code design stored on the SD card.

As firmware we used Marlins' sources, to update the firmware in the future you just need an Arduino board, so you are good to go ;)

Installation: In "Configuration.h”

  1. Change “#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER” (just remove the // at the beginning)

==> REMEMBER TO INSTALL U8glib to your ARDUINO library folder:

Upload the firmware, power off the Arduino, connect the panel, reapply power, and everything should work.

Some versions of this board have the notched connectors the wrong way around. If your controller only flickers and beeps, cut off the notches on the cables and insert them upside down.


There are some possible hacks to modify the display.
