I also ran into serious problems using a current Marlin build for Dual X. A two year old version i am using so far does work.
With the current release the X2 Carriage does not move at all and when X is homed only X1 moves and does so well beyond the X_MAX position, until it reverses and finaly homes.
Does anyone have a current Marlin version successfully running Dual X?

Did you changed any pins.h about your RUMBA,if you doesn't changed it ,that you might have a wrong wiring.
