Thanks a lot John.  I will read as I go along.

I am reading Mach3 Config Manual and I have:  Motor Outputs as shown.  I have Input Signals as XYZA+ Jog Port 1  Pin 12 enabled and hotkeys  I have XYZA - Jog Port 1 Pin 13 enabled and hotkeys.
In figure 5-5 of the manual it shows another Output Signal page.  This is where I am confused.  What output signals are these?

These are general purpose, not used for axis drives.  Examples would be a coolant pump, relay to operate spindle, door interlock.  And a charge pump if the BoB supports it - the one you have doesn't.

Thanks John

Well John, I think wiring is about done.  Would it hurt to use terminal blocks coming off the 5VDC Power Supply to hook all the Step+ and Dir+ to instead of running all those long wires?  Question:  the 5VDC side of the board, is that live from the db25 port or am I right to hook a 5VDC Power Supply to it?  Please check me out here.

AFAIK there isn't a +5v supply on DB25 - some BoBs have a USB connector with only the 5V connected for this supply.  Best to provide your own +5V.  You do need a common GND but that should be taken care of in the BoB.

Ideally all the signal connections from the BoB to the drives would use twisted pair with the +5V common at the BoB end, where you could use a terminal block.  This is to minimise noise pickup.

I am just trying to get my A axis motor to move right now.  If I am missing something someone please let me know.  I have been trying to get this going for over a month.  I am sure it is all me.

Thanks,

Ray

your wiring diagram looks ok for me, so the problem should be a bit more principal.

here:

is a good tutorial how to doublecheck the setting of your board adress.

after that here:

is a tutorial how to check your port/pin settings

after this is cleared out we can go to the bob and wiring.

TPS, I did the checking the pins on the db25 port on the computer with the arrow keys and I get 4.2 volts on both.  Maybe my parallel port is bad. left arrow should give low or no voltage.  They both give high 4.2 volts.
I might give up on XP and use one of my Windows 10 64bit with a USB port card.
