You must measure the length offset for every tool you will use in the job. You can then set the Z axis part zero with any one of the tools. Methods 0) Don't use length compensation. If you rarely use more than one tool in a job (e.g. mold surfacing with a single ball mill), then you don't need to use tool length compensation at all. Pros:
