Anybody with a s5 omp & dmm! (or anybody who can figure out this diagram!)
Alright, I REALLY can't figure out wtf is up with my OMP. On the FSM it says this:
|-----|----|-----|
|SM3|B+|SM1|
|-----|----|-----|
|SM4|B+|SM2|
-----------------|
And check resistance between B1+ and SM1 & SM3 and B2+ between SM4 and SM2, now, question is, which is B1+!? My mind tells me it's the middle top row, but when I try it, I get nothing, and if I try the pin below it, I get what the FSM tells me I should be getting, and I traced the wires back to the plug on the stepping motor, and it's confirmed that they're swapped from how they are on the stepping motor, but my question is, is it supposed to be like that, or did someone play switch the pins on my OMP and that's been causing my grief for so long? Any help?

Haha, does anyone agree that +b1 should be the top middle row pin? Or am I totally missing something here? I get error code #27 (stepper motor), so I'm guessing that pin is my problem
