The most common failure is the piezo disc leads desoldering.
If this is not the case then how long is the lead between the piezo and the piezo PCB and does it run in a cable bundle with other cables such as hotend heaters which have high frquency PWM signals? Interference can cause issues, try to keep piezo board on the head if possible to keep cables short.

Might be worth taking a multimeter to the VR1 pot and reading the value relative to piezo +. And the VR2 pot relative to piezo pcb GND.
Also measure GND to SIG voltage both open and triggering (more difficult without a storage scope).

Thanks, these are my first set of tests:Quote

I know basically how to get a probe working in Smoothieware, but I didn't get as far as grid levelling. I'm not sure there is a built in probe accuracy test, but you can send G30 and just record 10-20 values and stick them in a spreadsheet.

Good work. In terms of testing probe accuracy I'd just run G30 S-1 (not sure the equivlanent in Smoothie but this reports the distance travelled) and repeat it 20 times, then put values into a spreadsheet and get range and deviation.
10.415 10.4187 10.42 10.4213 10.4187 10.4175 10.4225 10.425 10.425 10.4362 10.425 10.4263 10.4237 10.43 Std Deviation = 0.005274mm
