ALWAYS disconnect power before working on your printer

Horror story...

In my efforts to do dual extrusion, I had a jam in the heat break. So I had to disassemble the hot end. Nozzle, heater carriage and temp sensor out, remove everything clean and reinsert. Well I like to use my LEDs to light the printer which means +24V is live at the heater, and there's an active ground connection through the temp sensor... zap.

Now my SKR board is non responsive. So got one on order.

So from now on I'll disconnect the temp sensor or just turn off the printer and use a work light...

In short. DA HAI is right. ALWAYS unplug your printer before performing any work.
