MCT Smeltery IO Mod 1.12.2 was inspired by Tinker I/O, and has some very similar functions. However, this mod requires fuel in the form of Snowballs to speed up your casting. Also the casting process can be completely automated by turning on the function to allow upgrades and casts to be inserted/extracted.
(To make the mod easier to use, you should grabbing Upsizer Mod as well as a mod that can allow you to make Snowballs.)
Features:
Fuel Controller
- Requires a form of Solid Fuel.
- You can heat up your Smeltery to much higher temperatures than with Liquid Fuels (Still required to make the Smeltery work). You can increase the Ratio with Speed Upgrades.
Casting Machine
- Requires Snowballs as Fuel for Casting Items.
- You can speed up the casting process with Speed Upgrades, Control it with a Redstone Signal, and increase the output capacity. You can also switch between Casts and Basin Mode with an upgrade.
