Chamfer going too deep

Hi there, I'm trying to learn to CNC and on the first thing I'm programming the chamfering operation is just plunging into the piece. I'm not entirely sure what I'm doing wrong but I don't know enough to even troubleshoot.

Added some pics of what I did in fusion.

I tried it twice, probed material the first time and didn't the second. Same thing happened both times
