Anyone having sparking around the pins used to align pei sheet

Hi was removing my pei sheet today and noticed sparks jump from pei sheet to the pins used to align it at the back of the build plate,anyone have this issue. Not sure what might be causing this but disturbing none the less.

No, I’ve never seen it…but I would check the heatbed wires.

That’s a pretty serious problem so I hope you unplugged it immediately and you don’t plug it back in until you’ve fixed the problem.
