Check the job and understand blocked Start

Start depends on current machine and path checks, not a completed checklist.

Step by step

1. Open Run Job and check the current file against the actual work datum, fitted tools, stock and fixtures.
2. Read each blocking finding. Correct its cause in the relevant setup section, then check the job again.
3. Review the complete transformed path, intended work coordinate system and clearance above fixtures. Ensure the probe is removed and inputs are clear.
4. If using the installed controller workflow, explicitly approve the current checked path before pressing START JOB.
5. Any source, setup, connection or reference change can invalidate approval. Review the new state rather than trying to bypass the disabled button.
