    Steppers and servos together?

    I did a search and could not find this subject.

    I'm running a C10 breakout board with 3 steppers right now and I'm looking at adding a rotary axis.

    Can I run stepper motors and servo motors off of the same breakout board? I see that both kits from Keling come with the same board. Just wondering if they can share it.

    As long as the servo drive has a step/dir interface like the stepper drives then it shouldnt be a problem.
    Assuming, that is, that your BOB has enough outputs.

    Could be...

    that I don't understand closed loop enough to ask an intelligent question. But, I have an additional parallel port that will jump off of the existing one I am using. That being said, I do still have additional outputs on the current c10 I am using. As long as I still have available inputs, will I still be able to have position feedback?

    As far as Mach is concerned the output is the same whether servo or stepper, you just use the applicable drive and motor.
    The position feedback with Mach is to the drive.

    If I am understanding correctly, Mach only knows what it is telling the drive. Position feedback and any necessary position corrections happen within the drive?

    Yes, with the parallel port version, a bit different if you are using the Galil card add on.
