@Ton80 I’m not sure what you use as a gcode sender, but I’ve been playing around with a macro for CNCjs that allows for a tool length offset probe. Your case is one of my exact uses for it…when you carved away your Z0 probe point. Basically the macro compares the lengths of the tools and applies the necessary offset for you. I haven’t had time to make a proper video (I need more hands, and my wife won’t stand in the garage long enough when it’s cold), but I did a quick write up and caught a video of the pocket being carved after the tool change.
