I really like this mod, it's super handy to have a way to do something productive with old machines and not have them clog up my inventory / logistics system, or have to blow up a chest just to get them out of my sight.
One thing I noticed was that the recipe for "Inserter Upgrade" breaks the intended progression of using an Assembling Machine 2 to automate inserter creation and, by extension, green Science Packs. This is because that recipe only requires 2 items to make, a burner inserter and an electronic circuit, both of which can be made in an Assembling Machine 1. This means that green Science Packs can be made before Automation 2, which is a possibly unintended change from vanilla.
I suggest changing the "Inserter Upgrade" recipe as follows:
crafting time: 1 second
materials: 1 burner inserter, 1 iron plate, 3 copper cable
This preserves the total amount of raw materials, as well as the crafting time vs. creating the electronic circuit, and since it requires 3 things, cannot be made in Assembling Machine 1.
