AutoZero Touchplate Probe issue - Broken bit

gSender 🐛 Bug
1

As you know, when using the XYZ probe, the bit will:

1- Touch bottom plate for Z axis
2 - Touch “West” and then “East” plate inner walls for X axis
3- Touch “South” and then “North” plate inner walls for Y axis
4- Travel (hover) to center of Touch plate
5- Travel (hover) to newly set 0,0 coordinates a few millimeters above 0 z axis

At random times, when using the XYZ probe, after Step 4 above, instead of going to 0,0,0 (Step 5), it will sink down evidently lower than bottom of probe, I just broke one bit when that happened, this is the 3rd time it has happened after upgrading to 1.51.

I don’t feel confident using this feature as it will damage my bits and the probe by poking at it

Problem with the probe using 1.5.1? Me too. It doesn’t function properly at all. Probe XYZ and it never descends to touch plate.

Is there a github issue already logged? Waiting on 1.5.2 before I try it, on edge 8 now and it has its own issues.

When this happens, do you hear a grinding noise? If you have more info or a video or console output that would be good

I always have loud music on due to the constant use of the vacuum, so if there was a grinding noise, I probably didn’t hear it.
I have downgraded to the latest 1.4x to be able to use the xyz probe, so I haven’t seen this issue anymore to record it.
I tried it a few times when on 1.51 to try and record it, but it happens at random, it’s almost like the Warner Bros dancing frog, it knows when only you are looking at it to dance.

Yes let me know once you get the chance. I spent over an hour the other day testing different probe styles and routines and couldn’t get anything to happen that was out of the ordinary. This could also perhaps be related to the issue you noted in your other post

Will do, thank you for looking into it!
As I’ve mentioned, I downgraded to 1.4x for the time being as I don’t want to risk my bits…
I’m actually planning on changing computers, so on the new one I’ll use 1.5.2, if it happens again I’ll let you know.
