@kn4ud The pulse width does change during the process (if I look at pin 11 directly but that's a whole other issue) but once the process has completed, a very small pulse remains.
@Zax I figured it might be which is why I'm going to try another grbl branch and see what it does with that. Also, what does left clicking the stop button do? I only ask because that caused the behavior to stop. I can't see the end of the gcode since I'm running the trial version.
