# This is the 1st commit message: MCP4728 consistency & fix ultralcd.cpp The MCP4728 DAC controls the stepper motor current strenth on the PRINTRBOARD Rev F and RIGIDBOARD V2 boards. PR #5792 on 9 FEB 2017 implemented default drive percentages but only on the RIGIDBOARD V2. This change moves the default settings to Configuration_adv.h. Also, ultralcd.cpp won't compile because of a type def conflict. Changed it to match the one in stepper_dac.cpp =========================================================== reword stepper curent section for clarity =========================================================== change name & improve comments =========================================================== changed name from A4JP to SCOOVO_X9H per PR #6139 # This is the commit message #2: fix typo
