    I don't see how inverting the direction in software could make the system and less reliable than swapping either phase wires round to reverse the motor. They have the same effect.

    Not making sense now.? . . . When you reverse which Axis carries on forward.?

    Why did you need one motor spinning opposite to other anyway if your slaving.?

    What BOB are you using.?

    Got to agree with Jon, sorry jazz! Computers are pretty good at assigning values to variables and then reading them again, they do rather a lot of that sort of thing millions of times a second... If your software can't handle that simple task you need some new programmers.
