I got all my PCB boards delivered... . I'm thrilled with the results with the minor exception that I forgot to re-size the stepper driver headers when I selected cheaper chinese driver instead of the pololu one. Not a big problem, I'll just use the more expensive pololu driver on those boards. I've made 5volt switching power supply boards, current sensing boards, op amp boards to expand the current sensing scale, keypad board boards and the main arduino boards. I also had foam cutter circuit board made up too, so I can make foam patterns for lost foam casting. Tomorrow I'll start soldering everything together.
