that chest has an me export bus set to autocraft an item and set to active without a redstone signal, and a me level emitter set to emit if theres 64 or more of that item, effectively turning off the export bus when i have 64 or more of that item in the network. theres a storage bus as well, configured to only accept the item im crafting
This ended up being the solution I went with. Works perfectly for what I need, and can stay hidden.
Thanks to everyone for the replies
