AGV drop of to rack slot instad of rack CP

There is a nice illustration of it in the manual https://docs.flexsim.com/en/22.1/WorkingWithTasks/AGVNetworks/AddingOffsetTravel/AddingOffsetTravel.html , but I cant find any information on if its posible to have the AGV automatically add an offset to the travel path to drop of at the slot location and not the rack controlpoint location.

I made an example AGV rack drop off.fsm

Do I somehow have to hardcode some offset travel (Seem to recall I have seen this in some other example) or what is the best way to do it?

Any offset travel behaviour of AGVs is defined in the respective trigger in the AGV Network properties. There is a premade option that has the AGV travel to the closest point along the path the destination CP sits on.

I cant set the travel to destination as the slot, but only the rack itself, othervise I get:

If I add the "Send AGV to Closest Point along Control Point Path" and set the destination to the rack, it still just drops it off at the center. The agv is set to

You need an offsetting task like travel to loc, unload or in your case, place offset task to invoke offset travel. Also the slots should be after the control point associated with the rack.

Works. But how would I do the same for pickup. I tried to change the place a custom task and change it to Pick Offset after the travel to pickup destination, but that doesnt work

Has the item been assigned a slot prior to creating the unload task? If not then the slot the item will be placed in is not known until it actually enters the rack.

I've attached a working example below.

Hi Felix. Yes. Did you look at my example? The issue seems to be that I dont have a unload task because im using custom kinematics to unload.
