So, my M90 stopped working...
After the fan stopped spinning when I flip the power I got concerned, and a quick look at the Melzi board revealed the negative power cable had scorched the terminal block.
Taking the board off the frame shows rthat the underside is also damaged....
The fan did spin up a couple of times as I swapped USB cables and checked whether it was my Pi causing the problem or laptop....
/sigh
Suggestions?
