Smoothieboard freezes when probing the bed using three points probing. Sometimes on first, sometimes on second , sometimes on third point. About 50:50 chance to have good probing or freeze. I’m using firmware from Jun 14 2018 (I think)

Connect to the board using pronterface, issue your levelling command, and see what error message the board sends you.
Thanks on your reply.
I’ve found an error. The Inductive sensor connector was loose.
