I think the thing that has not been covered so far and which may be the most important is why your machine went into E-Stop in the first palce. There could be a variety of reasons for this which will depend on your setup, for example if you have limit switches fitted then it could be a noise problem. Could even be something as simple as a dodgy keyboard.
Does this happen often? If it does then that is certainly the first thing to get sorted.
Another thing which although not directly related to this case is you must understand the difference between a Stop and Hold, doing a Stop when in motion will lose position, how much depends on your individual machine.
When the stop is pressed Mach immediatly stops all output to the drives but the axis may travel on slightlyy due to inertia and Mach has no way of knowing this and thus you have lost position. The Stop should only be thought of as an emergency stop, if you wish to stop in a controlled manner in a run of code you should press the Hold button and then if you wish to do something that requires the buffers to be emptied you can then safely press the Stop button without fear of loss of position.
