When one hit "Stop Print" option in LCD menu, the command buffer was not cleared. The printer keep moving until the buffer has been emptied. Actually I could not clear the command buffer as well.. I don't know why, it doesnt work as expected. I need to implement a routine inside Stepper ISR to handle such situation.
