Creating a new Machine or a new Recipe Map is a one-liner for me now lol. There is no better way to spam Machines and Recipe Classes if you just need a single Line of Code for any. And yes, the Recipe Map can be overridden to make other Mods Recipe Systems (or the vanilla Recipe System) merge better into the GT System (there are a few examples of that in some static classes below the GT_Recipe things).
But a little warning, this particular Class may get its Constructor changed over time in case I add new Stuff to the Functionality.
I figured based on what I see in it.
If I come up with a good version of your GT_MetaTileEntity_BasicMachine_GT_Recipe class with rotational energy support as well, would you want a diff (or just the file in full so you can diff it yourself, or both)?
I am wondering if Kinetic energy would be more accurate now that IC2 has added kinetic blocks (kind of...)...
Yes that is what I have done to most crafting Recipes already. Most Vanilla Items have Assembler Recipes now, even the Beacons, though it uses Molten Glass directly for them.
Have you thought about another config option to remove the vanilla recipes that your machines can make excepting ones that you need to make manually before the point that the machine is made?
