G30 fails in resurrect - [3.4.0RC1]

[OwenD]

I was just trying to save a print where I had a heater fault due to exceeding the excursion limit.
As I rarely print objects that cover the whole bed, my resurrect macros home X & Y and then prompt me to move to a safe area before it issues a G30 to re-home Z

This fails returning a "probe not triggered" error.
In actual fact, the axis moves down a bit before the probe (BL Touch) retracts, but it never gets near the bed (starting maybe 15mm away when paused).

I tried allowing movement beyond limits with no success.
The only way I could resume the print was to restart the printer, home X & Y and then drive to the print height and issue a G92 Z10.3

It's been a while since I've had to resurrect a print, so I can't say whether this applies only to 3.4RC1 or existed prior.

EDIT:
Changed the title as my description wasn't entirely accurate.
After the first heater error, the print was paused.
When it happened again the excursion was high enough to trigger the code I have in daemon.g which shut off the power.
That is why I couldn't simply resume

@owend it sounds to me that the Z axis position was set, but not set sufficiently accurately, before you used the G30 command to re-home Z.

@dc42
Thanks,
Not sure I follow entirely.
I'll do some tests when I get this print done.
