I was in the middle of a cut when my computer screen went black and I started to smell a whiff of that burning electronics smell. Was not sure if it was the laptop or the arduino but tried to find the smell and it was not obvious where it was coming from. I booted back up and the pc could not find the port for the arduino and it was not in the device manager.
I tried a different usb port and heard this noise coming from the stepper in the attached video https://www.youtube.com/watch?v=ufk-6aOLWHk&feature=youtu.be Anyone ever heard this?
I imagine I will just swap out the arduino as I know of no other option, but just wondering why the stepper would make this noise suddenly? Any thoughts on what may have happened?
