There isn't enough information to answer your question. If the Joy Stick is under computer control and the computer is sending serial commands to Marlin, you can wait for the OK to come back. But if the Joy Stick is connected to the LCD Panel, you won't be getting an OK. In that case we would have to figure out something else. Probably you could watch how much movement is left on the move in the Stepper Interrupt Service Routines.
