As you can see the picture, 3.5mm jack changed color. Im at the first use of octoprint, without printer I just surfed octoprint setup page. after a while, with metal smell, jack has burnned. (without fire, just changed color with smell)
I worry about fire when using with printer..
I have never seen that before.
First of all - if you still have warranty use it.
If you don't have warranty anymore I would suggest you desolder the headphone jack.
It's used for RCA and anolog audio, which you shouldn't need on your printer
You could use snippers to snip it off and desolder what's left.
