I've been running DCC++ on an Arduino Uno R3 + DeekRobot motor shield for a while now (with JMRI) I did cut the Vin trace, and installed the jumpers (being DCC++) Everything works perfectly well Now I want to install DCC++EX....I know I will have to remove the jumpers (not needed anymore), but do I need to remove the motor shield to program the Arduino with ExInstaller? Thanks
