Lots of things, including M2, reset/clear/unapply G92 offsets. If you want an offset that's more permanent, consider using G10L2P1 (G54). > 2> Similarly, if I issue "S3000 M3" in MDI mode, and then jog an axis which > requires setting the mode to manual, the spindle turns off as soon as I > start to jog.

Nope, unless you start it (using the nml command) after switching to manual mode. I've also considered this a bug in the past, but was told it was a feature. I'm still not sure it's a feature. > 3> If I have an estop while running a program and the tool is in the > material when the estop occurs, when I try to reapply power the axis will > jump to some commanded position following the estop.

When in "machine off" state, the commanded position tracks the actual position so you can (for instance) use handwheels and not get a jump when you go to "machine on" state. If this is not working correctly for you please say how we can reproduce it (and in what version of emc).
