I have a probe that bounces during the G0 move away after probing.

You can reproduce the queue error?

I don't know what you mean by "queue error" but here's my situation:
I have a pair of mechanical NC probes, one toolsetter and one touch probe. Both are a bit sensitive to machine vibrations (the machine is aluminum extrusions) so I added debounce to reduce those. The toolsetter still trips when I rip a pocket off, but that's useful ;-)
However, because of the debounce, the probe trip is now delayed and unpredictable, so I have to probe very slowly.
The probe operation is:
* probe towards, record hit.  Speed in the 1-2 in/min range
* probe away, record hit.  Average the hits to get the final result
* G0 away to clearance.
The problem happens when the "probe away" is still unstable during the G0 move (there really isn't a "deceleration phase" here).  I suspect it's a symptom of the probe design, as it gets *worse* as I go slower, as if the contacts were scraping past each other (yes, I know it's not that kind of probe).

"Queue is not empty after probing" error message, is the issue I am hunting for, trying to find anyone that can reproduce this, and see if my patch fixes it, I think your problem is something different, and it is correct that the machine stops when the probe is flickering, the "Queue is not empty after probing" is something different that in theory should not happen, trying to find users that get this message.
