OK. Figured out one bit. The scanning program scans "stich" fashion and the docs are slightly wrong, ie:
If the probe trips, the probe is retracted slightly from the trip point at the end of
command execution.
Well, it does not Now the probing program runs, but it only advances a few thou and then trips, without the probe tripping, so apparently does it trip on noise. Must put a scope on the input and look.
The probe is quite like this one:

And the breakout board is a:
