My probe has about a 1/4 in crushed part with a small hole in the middle of the magnet tip. My probe does not seem to work Do you think the crush and hole are preventing it from completing connection? ---

Hello and welcome Jeffrey, Did it come like that? Or did it get crushed? I expect you will have to email [support@onefinitycnc.com](mailto:support@onefinitycnc.com?subject=After-sales%20Technical%20Machine%20Support) with a picture. I know what the inside of the magnet tip looks like - the wire came loose and I had to take it apart and solder it on again. But I can’t quite figure out what you are referring to without a picture. Is the tip still magnetic? Can you test it for continuity? ---

I’am not sure if it came that way or if I hit it on something ---

The tip is still magnetic
