User error or a strange event on probing. Broken ruby tip.

I have had probing working for a bit and its been solid.  But today I had a strange event happen, not sure if it was me or something else.  I don't believe the settings are different than before.  Not sure what to even check.

I was probing Z only, and things started fine, the probe was going at the slower rate, tripped, then instead of backing off (Z+) it continued at the fast feed rate (Z-).  Another ruby tip smashed.

I tried again, and it did the same thing.  For a third test, I jogged x-y away from the part, and also jog z+, and tried on a "test" part (just a flat pen held off), and it worked fine, and now it seems to work fine.

What would cause a probe cycle to continue vs backing off?  Or did I make some mistake.  Either way, I want to avoid this again... probe tips are expensive.

Sounds like you have some electrical noise or maybe need to add some debounce. Remove slow feed by changing to 0.0 and just try using fast feed rate. If you move to slow probes can sometimes double trigger which cause issue. It's best to use a bit more speed. As long as you calibrate at the speed you probe at, you should retain consistent repeatable results

Is there any logging behind the scenes to know that really happened? As this was working reliably in the past, I was not 100% focused on watching it. It would be good to know when it was tripped and what the feed rate and direction were.

Thanks
