I think there is a mistake in this tutorial and I have found a solution.
On page 3 item 7 there is a task to remove the ParametricPallet
on page 10 item 2 the feed task is set to pickup the ParemetricPallet
However, we already removed it and the human doesn’t pickup anything.
I simply replaced this with a feed task for VCCar_DoorSheet and the human picks up the doors.
Thank you for your feedback. On page 10, item 2 you are instructed to select the All checkbox. That means everything contained in WorksProcess will be fed, regardless of id. Since there is a need for an id of “Sheet” in another work statation, those items are picked up and placed by the resource.
Step 2 did not tell you to clear “ListOfProdID” for two reasons: 1) it would be redundant, and 2) it is not required.
If you wanted to take a different path, you could clear “All” and set ListOfProdID to “Sheet” and the process would still work because in a previous section you were shown how to change the ProductID of the door sheets.
One concept at work here is the need for parts. If there is no need for a part in a different station then the part stays where it is. Also, if the work station containing the part does not indicate it has a part then the part will not be used to complete an order for the part. A Need or NeedPattern task “requires” you to give a product id, i.e. there is no “All” option for need type tasks.
Sorry for the confusion. By default, the Feed::ListOfProdID will reference a product id used at the station. Not sure if that was changed in latest version of Works library.
