Re: Power supply shuts down when heated bed MK2a is connected.

Hmm... I removed the PCB heatbed and it still reads the same resistance as before; I also inspected the mounting holes visually (they're close but not obviously problematic) and by testing with a multimeter I didn't find a short between the electrical connections on the heated bed and any of the mounting screws. I had a resistor and LED installed before but cut them off to try and eliminate potential problems.

Here are some pictures of my board.

It looks like there is a thin sheet of metal embedded near the bottom of the board - maybe my wires are connecting with this somehow, causing a short?
