Ok, now I got it, but I am convinced that it would not work in joint mode anyway. Please correct me, if I am wrong. Each joint is completely independent in joint mode, AFAIK EMC is built so that assignements between joints and axes are ignored in joint mode, so also Your suggestion with use of U axis would not work, because, as You said, in homing U is homed separately, so it is treated as separate joint in joint mode.
There would be an option to modify the LPT cable so that X step and X dir signals go to 2 pins and so that 2 drives receive those signals. But this option automatically excludes the possibility of homing each gantry side separately. But I need separate control of each gantry side so that machine is squared and kept straight each time.
