I think the crafting recipy is a bit simple and cheap compared to what this machine is able to do especially with the potential of having more mods installed which have tools that benefit greatly from this repair machine.
However this being said after customizing it a bit i greatly enjoy this mod (crafting wise, the other bits are very alien to me to this day).
Sorry for the bit of a delay, forgot to check up here.
Yeah at the time I just threw a recipe together, I focus on multi-game support, so I'd need a good craft recipe that plays well with Minetest Game and MineClone2.
Here is a good spot to contact me as I usually check here when I think about my mods and such. (ContentDB also provides me a centralized spot to see notifications, as opposed to Github where I'd manually have to check each of my mods repos)
Feel free to use it in your modpack.
I myself was thinking of making a technic-like modpack that includes this where it consumes power/energy what not to repair tools, and make it where the upgrades play with the amount of power/energy consumed (faster repair rate, higher consumption).
I am currently still learning how to do things. Currently I am working on a rather weird concept of nuclear processing, using fuel rods to bombard isotope rods to get a desired product. No electricity is involved however until i figure out how to do that, it would be nice to add that later.
Ah, yeah same here on the idea of having this require some kind of power / energy.
So far that sounds like it will be cool.
Interesting fact, I was initailly thinking of using Technic as a requirement of needing energy in order to repair tools (but then I'd loose multi-game support, and Technic already has it's MV Tool repair machine).
