Can't craft the cobblestone framework controller?

[KelseyRemy]

I've checked the recipe over 5 times and I have it right and I can't seem to craft it in a regular crafting setting and I'm not sure why or if it needed some special crafting circumstances?

No, it's simple and normal crafting.

Then I'm not sure what I'm doing wrong do you see any obvious mistake?

addShaped(cobbleController, "sis", "lMw", "pzp", 'i', "ingotIron", 's', electricSteel, 'M', machineChassi, 'z', zombieBit, 'l', Items.lava_bucket,
              'w', Items.water_bucket, 'p', crystal);
          addShaped(cobbleController, "sis", "wMl", "pzp", 'i', "ingotIron", 's', electricSteel, 'M', machineChassi, 'z', zombieBit, 'l', Items.lava_bucket,
              'w', Items.water_bucket, 'p', crystal);

assuming you're not using a modpack that changes recipes, your first row should be "electrical steel, iron, electrical steel". The pic looks like all steel to me.
