I've been researching the techs, but the ones for plates won't work. There's no way to "select" a recipe in them. Do I need another mod for that?

you need to use a mod that adds furnaces with the ability to choose recipes

hey man thanks for the latest update.. in version 0.0.6 it used to work just fine if you removed and placed again the electric furnaces did something change for the latest version.. also do you know the mod that adds recipes to furnaces?

thanks

sorry but i don't know mods that adds recipe for the furnace, anyways the support of the furnace is not complete, if i remember the planner don't work with furnace

Krastorio2 at least adds recipe selection for furnaces, due to it having furnace recipes that return multiple results,

Essential mod:

furnace recipe selection
