Anything related to printer controllers not being Duet, RAMPS or Sanguinololu: microprocessors, motor and heater driver circuitry, gEDA/KiCAD issues, soldering tips, etc.
I know there is no support as of yet for the driver for this OLED bit I am curious if anyone has tried it as it would be perfect for my new Smoothie Mini powered Delta Mini Kossel.
