Hi, i was following this tutorial and im having trouble making it work in my simulation. i assume the issue is because im using a stack feeder that i customized to stack products of a certain ammount and that my pallets are made from a feeder process. any idea how to make it work? the R shapes are meant to go on the pallet with the red container and the little wooden pieces are meant to go on the pallet without the container. one per pallet. they should be going on the pallets at the first “from conveyor” process.

Okay, let’s take a look at the problem. First of all, neither the component “R” nor the wooden pallet in your simulation document can successfully flow out to the next flow node, and looking at the Flow groups, you can see that you have set up all your flows centrally in the first two Flow groups, and in the case of “R “ and the wooden pallet are not set in Flow groups “#4” and “#5”, which is the reason why they do not flow.
At a cursory glance, this should be the only problem so far, you can modify it and try it on, and you can raise any questions you have with me again.
i got the first pallet working and the second pallet gets loaded as normal but it doesnt get transported to the conveyor after.
i made a few changes to the process aswell.

I modified one of the nodes a bit and got him to run successfully, but, as you can see, there are still some problems with the logic, but you can refer to my modifications. 
i got it mostly working but the issue now is that the R shapes and the wooden pieces
that have already been put on the pallet and have moved on the conveyor get attached to the new pallet and get taken off the old one. How would i stop that from happening? I hope i explained it welltestiranje (2).vcmx (48.2 MB)
I’m not sure if you understand the part I changed for you before, the part marked in yellow, which I didn’t explain to you before and may have caused some misunderstanding.
The reason why we need to set the ProductIn variable to Null is because, in the Process module, the inflow approach is not a simple assignment relationship like “a=0” in python, it’s more like “list.append(a)” in python, it’s added to this variable,which means that if you don’t clear it, all subsequent components will be affected, and you mentioned that your component “R” and the wooden pallet will be moved along with the subsequent ones because of this problem.
So, you need to add two more clearing operations (in the red box).
