Ok Boyan thrown some motors on controller and CANNOT make it Slave the motors together. changed all settings and still no Joy.
The A/B selection makes no difference. Setting A pulse to from Pulse/Deg to Pulse/Circ just makes the A motor ONLY spin continuesly with no control over it. Pulse Degree does exactly that moves in Degree increments per pulse.

I'm also not impressed with the Crap Terminal connectors on back what load of rubbish. Tiny holes and half of them won't clamp properly. I see loads of potential for trouble with lose or fallen out wires with these things.!!
