Error message. New user

Hi I’m a new user. I’m on my third job using the journeyman and I’ve run into a problem. See error messages. I’ve tried different Z positions and restarted the con.troller and re-homed a few times. What am I doing wrong here?

Thanks. GMF

It seems your g code file is attempting to push Z below the maximum soft limit of travel, what is the height of the project?

The project is 3/4”
