Trying to use Ender IO Item Conduit with an Advanced Item Filter to combine damaged armor pieces in a Cyclic Assembler. I want all damaged armor to go into the Cyclic where it is combined with another piece of damaged armor repeatedly (by looping the Item Conduit from machine output back to machine input) until it becomes an undamaged piece of armor. At that point, I don't want the armor going back into the machine, I want it to continue onward in the Item Conduit to my main inventory, which is where the Advanced Filter can help me. But I can't get it working properly.
I set the whitelisted Item Filter to ignore Metadata, and also ignore NBT data. But I activated the button that says "Fuzzy match for any damage", and that button shows "99%" which means armor at 1-99% damaged will go into the machine but armor at 100% (i.e. undamaged) will not go in. Is that correct? However, the undamaged armor IS going back into my Cyclic Assembler which I don't want it to do. Why is the Item Filter not working? Do I need to allow NBT data to work with the Fuzzy setting, instead of setting the Item Filter to ignore NBT data? I tried that, and it didn't seem to work so I'm stumped.
Is armor damage stored as Metadata or NBT data? I can't even remember which it is, and a bit of internet searching didn't clear it up for me. I've tried all combinations of Metadata/NBT/Fuzzy settings on and off without success. I'm beginning to think the Ender IO Item Filter is broken, even tho I know I'm a dumbbell and there's a high chance of the problem being me.
