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?

Seems IDEX used RUMBA was X,Y,Z,E0,E1,X2.But it no work well even doesn't work at all.The older version 1.1.0.RC6 that direct define X2 can work well,and anyone knows how to use M218 to set z offset ?My set was M218 X305.2 Y0.5 Z0.2 R0 and used M605 S1.please give any advice.

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