Sorry, I did not read the complete thread. Maybe there is an easier solution to this problems: How about if emc would store the gcode position after a stop/emergency shutdown,i.e. the last completely finished move. And if there would be a "continue" button, where emc will replay the complete gcode in fast mode, without actually sending any moves. Only if the stored line is reached it will continue to send. Its a bit complex, with loops and stuff... It would be necessary to assume a save path to reach the position initial to the last complete move. If the user knows this, he can manually jog to a safe continue position where a direct move from will do no harm.
Additional Idea: having enabled/disabled "breakpoints" in the gcode-view. Users can create/activate/disable/delete breakpoints in given lines (ignoring multiple moves per line). A stop of any kind automatically creates one disabled breakpoint, maybe with a additional label of the current date/time. This breakpoints settings are lost if a new gcode file is loaded by "open", if reload is pressed, the line breakpoints numbers are conserved (potentially usafe, if lines shift, but mostly usefull). greetings, bernhard..
