Prusa I3 w/ Melzi 2 board. I can't change settings because the Configure EEPROM settings option will not highlight to be selected. Can't use gcode editor. Nothing happens when asking for Z Steps info. Downloaded Repetier 1.5.5 but still can't select settings. Is my board just a piece of crap that doesn't allow settings changes? Repetier won't allow questions to be asked. Starting to get pissed. Printer works great accept that parts are 1.5 mm to tall. HELP!
