    Hello, Chris,

    Nice job :). I'm asembling I3 now and have some problems with Ramps1.4 and LCD display. After wiki reading and some tests I still can;t work with LCD: it hungs when walking thro meniu. Can you share with me Marlin setings?


    With best regards

    Saulius

    Thanks, Chris. Can you share Configuration.h file?
