Hey there frneo,
I know myself and many others have been hoping to find something like this for quite some time now, so thank you.
I just gave it a run with 20 DC hammers, and it works flawlessly. Fantastic job.
One thing that I noticed as I was watching it for a while. (And I'm not really sure if this is really an option, but just a suggestion if nothing more.) I believe that you could almost double the speed of the script if you were to craft the weapons directly into your unravel bag. Drop your ingots into that bag and crafting there would cut out the need to drag and drop every item made into that container. Then after crafting 6, or however many, scan the bag and pull any that qualify into your keepers container.
I've always liked crafting directly into my unravel/recycle bags just so I don't have to move things around.
Regardless, your script is fantastic and I thank you for taking the time to put it together. I have thousands of low end hammers that I've been wanting to burn, but doing them while sitting here was awful boring.
Thank you.
