With thaumcraft 4.1 crucible automation is very easy. Arcane infusion isn't that hard too, you can just pump items to pedestals using itemducts, but arcane workbench crafting is very tricky. I used item shifter, but it totally don't work, turtles were much better, I managed to get items into arcane workbench, but I didn't found a way to pull the final item out of it (peripheral.pushItemIntoSlot() or peripheral.pullItemIntoSlot() don't work), also I don't found a way to move the wand. So i ask about a help, but I think this is impossible, for now. Here is my code for automatically filling the arcane workbench, you should put items to the turtle, like if you will be putting then into arcane workbench (slots 1, 2, 3, 5, 6, 7 , 9, 10, 11)
