CNC is unresponsive to manual x y z movenment

Andy, thanks for your response.

I have a closing the circuit on contact type. That kind of behaviour was occuring when running gcode. the router would go drive to plunging point and start drilling down the piece.
Would that still be characteristic of a dodgy zero plate wire? I will have a look when get to workshop though.

Any idea why the manual operation of xyz controls is not available all over sudden? I did check all the wiring or stepper drive and main board, all as should be. Can't see any visual
problems.

thanks

Problems like these can be a nightmare to diagnose because could be anything from a loose connection to a faulty keyboard.
In fact my first suggestion would be to replace the keyboard if you have one handy to quickly eliminate it. It's quite common for keyboards to go down.

Next would be to do a Re-install of mach3 and any plug-ins if it's using any because I've seen it do things like this before. Save your current profile XML and re-install mach3 then load XML back in and you won't have to re-set anything.

After that it's just a case of check all wires in case loose or damaged. Then if still not playing nice then I've no idea other than a computer issue which I very much doubt.!
