OK swapped z axis pins from 6 and 7 to 4 and 5 as they were empty it works so not the board itself so is something to do with the signal from a axis pins how to test please?

First, get a good soldering iron and resolder those pins on the IC's, the one on the right side of the picture looks especially bad.

Attachment not found

OK cleaned up a little bit better
Could you walk me through a step by step process of what I'm doing to check learning as I go. What part pulls the signal to ground. Could you explain the process thanks in advance
It looks like they had problems before

Stall.
Velocity is to high, lower the velocity in the .ini file.

Made no difference on velocity. I swapped over x and a axis on drivers the fault follows the driver wiring or driver need to rule out grounding issues can you tell me what I can put my multimeter to and how to test the signals? ?
