I have the Rumba up and running with Marlin(lastest from github) without EEPROM_SETTINGS enabled, and it seems to work great. BUT i want to enable access to the EEPROM to make calibration easier. When I enable it the board seems to malfunction, M503 displays nothing and all the steps per millimeter are no longer even close to what I have coded in Marlin. The board also drops the USB port randomly when EEPROM_SETTING is enabled. If I turn eeprom back off it starts to work properly again. Is there a way for me to get access to the eeprom?
