Machine home versus work datum

Home establishes the machine reference; a work datum locates your part within it.

Step by step

1. Clear the homing route and check switches and safety inputs using the machine's setup instructions.
2. In Machine Control, explicitly approve HOME ALL. Wait for completion and a trusted position report.
3. Your fixture corner may be opposite home, beside home or elsewhere on the bed. Measure its machine XY coordinates; never infer them from a corner label.
4. Choose the job's work coordinate system, normally G54 unless the CAM file calls for another. Set the part's work zero at the locating corner.
5. Rehome after loss of position trust. Recheck fixtures that have moved or been removed.
