I operate RepRap java software with gen 6 electronic board.
With the "20110107_GEN6-FW_Mendel_Parts_TCST2103" firmware from mendel-part the main problem was the use of "debug" as keyword for debugging when the reprap host java sw is using "//".
I have modified the firmware from mendel-parts by re-introducing some parts in this firmware some parts of the reprap firmware, mainly the "talkToHost" function and hostcom.h.
It works but I have not a clean firmware code at this time and I think that I will now start from the new mendel-part firmware, Marlin, for new tests.
