help needed with my set up

none of the videos I watch show the 2 end pins connected .

I am grateful for the input though as it really is stressing me just now

What do you mean by "end" pins?

You should make a simple drawing showing your connections. I have two similar BOBs and they work flawless since several years. You should also check the voltage (logic levels) on the inputs of the BOB. When you change direction the DIR signal should change polarity from high to low or low to high. If that does not happen no direction change will take place. Also, eStop must be configured right, as well as the limit switches. You should also know that just because something worked before does not meat it works today as well...

It is also not a good idea to use the USB cable as power supply for the BOB, even if everyone you talked to does it. Again, just because it works for them, it does not mean it works for you. Not all USB are created the same, and by definition USB can supply maximum 500mA, which normally should be enough for your BOB, but if something is wrong with your PC then you may not get the needed current, or maybe THAT specific USB is not able for it. Anyway, external 5V supply is better.

Is it Mach3 you are using? Are you sure nothing wrong with the configuration of ports and pins?

I’m no expert but I have never connected the enable pins to anything as my understanding is that giving them 5V tells the driver to halt (reverse of what you migh expect).
If this is the case then remove the 5V cable to en+ and any cable on en-
Hopefully someone more knowledgeable can confirm this

I don't have any limit switches or e stops attached at the moment . I have taken it all apart to try and work out what is going on . all I have is 1 driver 1 stepper the powersuply and the bob. I get 3.7v on the input side of the bob on pins 2 when I jog left I get 0v on pin 2 when I jog right . but all the output pins read 5.1v dc . nothing changes on any of the out put pins . if I connect the stepper there is no movement. I can feel it get hard to move and a small buzzing but no movement when I jog.
