Hello,
cool mod! But why is the recipe with 48 furnaces and not with 24? You only need 24 for a full compressed belt. That would be more logical.
Greetings

One side of yellow belt is 24, but both are 48. You can try to change this parameters in the mod.

Thanks for the fast response. But the electric furnace have a smelting speed of 2 and you need only 12 on each side of a yellow belt to fill it.
But maybe I mess things up a bit. :)

Like all stuff in the game - two time better costs fourth time expensive. See the recipes of transport belts.

You can open the mod and just change them: 47 will be too few, 49 too much.

Yeah, thank you. I changed the amount to 24.
Please, can you tell me what line of code is responsible to the hardness of the machines? I mean the time it takes to mine one furnace (now it's 5 seconds or so, way too much)
Greetings

/lib/entities.lua:18
minable = {mining_time = 5, result = name},
