Thank you Nick. Off to try that now. I did make a little progress during the middle of the night in a "it's playing on my mind" moment. I found and downloaded "routout CNC" and it sorry of responded. It have some odd movements in response to jog but relatively uncontrolled. But it did at least m move in x y and z. That has made me suspect that the "driver" may be the culprit. Taking the cover of the breakout board now.
