I have had this passive probe seems like forever but never used it. I was trying to use it today and it was off so I was trying to run the torch calibration routine and I was getting weird thunking sounds. Somethimes it would run fine, most of the time in sporadic places I would get the thunking. The DRO would still be moving though, even stranger, sometimes the Z would be moving as well and it should not be.

I hope someone knows how to make this work right....
