Browse Source 
Uses some code from https://github.com/fluxionary/minetest-crafting_bench, with the author's permission.

- Improve item movement log messages
- Only allow one item per stack in the recipe field
- Adding a recipe doesn't take the items anymore
- Add LBM to move leftover items from >1 items big stacks to the craft output
