Hello everyone! Thank you for the help provided by the community previously; I'm fortunate that my current small model is running smoothly.

Waht's my finding~If the "Unloading Required" option is not checked in the machine tool dialog, the unloading sequence defined in the Gantt chart will be ignored. This issue becomes particularly evident when the same machine tool needs to unload different materials by both AGV and workers.

At Station C, each unloading operation is carried out by the AGV and the workers in sequence (first the AGV performs the unloading, then the workers perform the unloading of another item).

In this case, the "Unload on Request" option in the machine tool dialog box must be checked.

Hope to be of help to those in need!
