Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I saw zero activity on the pins of this module, the pins that join it to the main control board.
I wonder if anything is getting to the sockets for this driver board...

I will have a look at the comparitor, maybe it's shorted.
