Many thanks. I did as you advised and now I have a working printer again.
Your help is very much appreciated.

Granpa Pig solution worked. Disconnect printer, shut down completely, have a cup of coffee, turn power back on, restart printer. Z probe now working correctly. Printing a test job right now.
Thanks again.
