If you've already wired up your heater/thermistor you'll probably know the trap I fell into. If you haven't, and plan to using this rev or the Gen6 board, you'll get to it and then say "oh... I know what he meant now!" :-)
It's a small think, but I think worth pointing out that by reading down along the edge of the board, you would take Pin-1 to be on the left (at least I did), but see photo below, and in fairness, it is stated also on the wiki (if in a little detail well down the page), that Pin 1 is on the right as you look along the edge of the board!
With the heater connected up correctly I was ready to start some tests. I'll keep them to a separate post.
Thanks for viewing!
