Hi @ahmedabdlsalamm .

Could you elaborate what you are trying to do? It seems like the “First Fit Decreasing Bin Packing” already tries to create the most optimal cut lengths per bar.

i want to reuse the waste as a stock again so
i want to use it and when it fits with minimum waste to remove the length fom the list and then go to the next length

I think that this node doesn’t really work with that, since you are giving a BinSize/ Stocklength. I think the node itself already tries to find the most optimal cutting length for the length bar/ bin you supply.

Let’s say you have a metal bar/ rod of 10m. and you use 9m., now you are simply left with a rod of 1m. you can’t just add that waste to the stock again since you will always just have a 1m. bar.
