1. Select any recipe for an assembling machine
2. Insert item directly into it's inventory: /c game.players[1].selected.getinventory(2).insert({name = "iron-plate",count = 1})
3. The item inserted into the first slot, regardless of the recipe filters

The inventory slots of a crafting machine aren't restricted to what can be put in them. - nevermind that - You can manually put items in the wrong slots as well.

Not really sure if that's a bug or not. If you call entity.insert() it will put it in the correct slots for the recipe.

I just have tried to manually put item into this exact slot, and it said: Only electronic circuit can be inserted here, not Iron Plate.
As about entity.insert(), I'm aware of it.

You're correct. I was thinking of filtered inventory slots (the hotbar and train inventory).

Assembling machine contains regular inventory. The inventory itself doesn't know about filters. The filtering logic is done by assembling machine code.
This way you are manipulating the inventory directly. Hence the filters are not applied.

Safer and generally recommended solution is to work with the entity directly:
This works as expected putting the item to the correct place. This uses the same mechanism the inserter would use when inserting into assembling machine.
