Does this screenshot mean that pins 12 & 13 are fried on my PC?? Nothing is hooked up to the port yet. I'm running normally closed x--(11), y--(12), z++(13), and [x++ y++ z-- in series].
Why, with nothing hooked up, would my led indicators not light up on m2--limit, m2home, m3++limit, and m3home?
Thanks,
Rooney
