I may be out in left field on this, but how many combinations are there? I assume the relays are already hooked in to assigned outputs, if so possibly installing a BCD switch in to four inputs gives you a total of 16 combinations, you then writing a i/o macro to control the output relays, depending on the switch position, similar to how a feedrate overide would work. What do you think?
