Yeah, the bent metal bracket that you bolt the extruder parts to (the stepper motor, heater block, fans, etc.) is what I got shocked by.

I was honestly too afraid to touch any other part of the printer, so I can't say whether or not it was localized to that area.

Was thinking maybe the heater block "humming" when I put my finger near it has something to do with this, and maybe there is a short in the heater itself, however there are no visible wire breaks, and the wires are not touching, and they are connected solidly to the heater. However, it is the only high amperage component in the heater block (the only other electrical component being the thermistor), so it is the only thing that could be causing the problem if it's only that specific area that shocks me.

I guess I will try to see if it shocks me anywhere else tomorrow, though honestly I am scared it could electrocute me.
