help needed with my set up

[A_Camera]

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?
