Z axis too high

After uploading firmware, I find that the Z axis is set way too high. (About 80mm above the bed).
A G28 will not change the Z level.
The printer had been working ok before the upload.

Also, each new G28 I issue causes the Z to go still higher

sounds like the Z probe is being triggered all the time. So each G28 you issue it moves the bed and reads a probe trigger and stops.

Check if you need to invert your probe trigger.

I think I had the wrong firmware loaded.I uploaded Jim Brown's Easyconfig 1.1 and the printer responds correctly to the G28.
