Hi Jack,
I think you have your wires crossed, EMC is the control. It puts out pulses for step and direction of each axis via the parallel port to the driver cards. The exception here is with 0 to 10 volt servo drivers which may be internal or external to the computer. EMC can drive either stepper or servos with the right driver cards.
Regards,
Terry
What's the nature of the conversation between EMC and a servo motion
control card? Can EMC be reasonably viewed as a black box with g-code
and encoder signals going in and strings on some alphabet going out
to a motion control card? But what alphabet and what strings? What
kind of interface exists between EMC and the controller? I suppose
different controllers accept different sets of commands, so EMC must
have a place where interface code can be grafted on--right?
Thanks in advance.
