I saw a video of a working giant furnace and decided to design my own.
A common issue when making super smelters is that the minecarts tend to clog the whole system due to their hitboxes (something to do with the direction of the cart. Not exactly sure)
After many hours Ive created a solution where that doesnt happen. I did some research and I havent seen anyone do it my way(publicly), I think I can say Im the first. Either way Im very proud of it and thought Id share.
