thanks jazz.. yes a type B is the slave

Ive done that... and it works fine now in one direction,.... but when I change direction one axis goes in reverse and tother carries on going forward

Well really it's better to change the wires because of the way the rising pulse works but you can just change it in software and it will work fine. If you have any funny happenings like missing steps on that motor then change the wiring but 99% of time with modern drives it will be fine.

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.

No need to apologise to me.! . . . Wasn't having a go at you or meaning not in mood for answering your questions just not going to argue for the sake of it when it wouldn't help anyone and turn the thread into another one of is " Up man ship" trips.!

So are you working has expected or would like now.?

[GEOFFREY]
