Atlantic Santa Fe legacy engine 1484 (6-11117) Skips chuffs. Mike Regan, had mentioned to me that the first chuff uses the micro switch. After, that it is the motor driver board that provides the signal. Can anyone verify this is true?

I would say that if Mike R. told you that, you can pretty much count on it being true. After all, he's the guy that the guys here ask.

This.
it was s quick York conversation. Just, trying to verify.
I had the same issue on my Legacy 10-Wheeler. I replaced the R4LC board and that fixed the problem.
Odds on favorite is the chuff switch. Hard to imagine why the R4LC would fix it, that must have been a unique failure. Usually, if it's skipping chuffs, a simple slight bending of the actuating arm on the Cherry switch will fix it.

I agree, which is why I replaced the cherry switch first. 
I had the exact same issue, so Marty F. suggested I replace the R4LC which fixed the problem.
That's probably the second step Allan, the chuff switch goes right into the R4LC, so if it's not the switch, it's the board. 
I tend to try a $2 switch before the $55 board.
