Well, rewired (using mainly the existing cables) and reworked all the earthing for the cable shields + a new encloseure and ------ IT WORKS!!
Obviously very sensitive to noise as my Duet wasn't.
Anyway thanks for the help and for encouriging me not to give up.
Hope this assists others.

Well thanks to those who replied. However not bring able to sort out even simplest of problems and having spent 2 weeks tryng to do so I have reverted to my Duet3D board, which incidentally, works fine.
If anyone wants a cheap 424 + 407  then contact me - they are yours.

Anyway it's exactly the same setup and wiring that I used with my Duet3D board which worked 'straight out of the box' with no issues. Worked perfectly!

All my high current (motor) wiring is run in double screened cable.
Probe wiring is completely separate from all other wiring and short (18" or less)

Probing the centre of a circle.
Works intermitently. Will start to move but will stop on contact with one of the 4 surfaces and give the message below.

X axis is moving to a requested machine position.
Y axis is performing a touch move.
Machine just hangs there until reset.

Will perform a complete touch action once in approx 5 or 6 attempts.

FINALLY solved the 'Disabled' message by lowering the current on my stepper motors and reducing the pulse rate to 400.
Set the homing on Y axis to both motors 1 & 3 and allocated the same limit switch to both motors. Now Ref all axes works but I still can't get 'return to home' to work.

Probing still a problem  Set the prep distance but can't see how to set the distance the probe is to move after the Prep move until it should touch the surface. (Prep move + test move = total probe movement)

Bought Mach4 and a 424+407 (build3804) and spent a week trying to get it to work but with no luck.
Cant get 'Ref all Axes' to work. X does home but on hitting the limit switch maching retracts and goes into 'Disabled' mode and stops.
Goto work Zero doesn't work at all - no movement, machine goes to 'Disabled'
Probing - Z moves but on touching plate maching goes to 'Disabled' and that's the end of that, same with corners.
Havn't even bothered with the 407.
Viewed a post which recommended reverting to build 3390. Did that and the only bit that changed was the the 'Goto Work Zero' works, all else the same.

So it seems that the software keeps tripping into 'disabled' mode.

Thought I was upgrading from my Duet board but now I think I'll revert to it...
