Hey Butch,
if you mean the Onefinity Controller on Standard Series (not the Masso Controller on Elite Series), you can pause the program by pressing the “play” button and continue by pressing it again, but you can change nothing during pause, especially not jog around or edit the program.
If you stop the program, you can only start from the beginning (or load a different program).
If you want this, you got to switch to another controller. Any controller will run with the Onefinity CNC, you can even buy the Onefinity Standard Series machine without the Onefinity Controller.
