Hello,
is it possible to connect 5 pcs stepper motor's drivers and one servo motor (MCAC760 driver) to one breakout board like this: http://images.tupianguanjia.com/bin/7333/00200-005.jpg ?

Yes

[Patuc]

can you say how?

[ger21]

Each requires one step and one direction. signal.
You have 12 outputs, so 2 to each drive, one step and one direction.

but servo motor driver mcac760, in manual wiring diagram show not 2 wires as stepper motor (step and dir), but 4 wires -dir +dir -step + step

Dir+ to direction pin
Step+ to step pin
Dir- and Step- to a ground pin

thank you!

why I am asking this: I have rotary table, the 4th axis is rotates 360 degree without backslash, but 5th axis (which rotates 90 degree) handle have backslash and it is not constant. I have 2 stepper motors for this rotary table, but 5th have not constant backslash, so I thing to use servo motor with encoder (servo driver mcac760). I think to separate servo motor and encoder and connect motor to 5th axis handle and encoder connect to main shaft. I make two pictures to be clear: red arrow show where I connect encoder, green arrow show that the motor with wires turn table 90 degree angle. That handle where is motor with wires have backslash.

What do you think about this idea? Maybe someone can offer better problem solutions?

[Patuc]

no one?

Are there some people people who can help? Or this forum is died?

If there is back lash between the servo motor and its encoder, it is not going to work very well. There will be some very nasty oscillations and overshooting.
