The 7i76 only provides one encoder input since it's a stepper card not a servo card. Can you point me in the direction of some docs on loading a software encoder counter and configuring it for MPG use (one MPG, with axis and step select switches). I'm new to LinuxCNC so it takes me a while to find things in the docs (if they're there).

Configuration wizards by there very nature can only support a small subset of that. You can certainly load a software encoder counter and use it for the MPG. But if the Mesa card provides enough encoders (one per servo axis, one for the spindle, and one for the MPG), you might as well use a hardware encoder counter even though the speed is low. If you run out of hardware encoders, then use the software counter and a couple of GPIO pins.
