Honeycomb Graphene and Arc Furnaces needs some sort of change to make arc furnace worthwhile over normal furnace, cuz as is its a pain to use them, like I can brain off for normal furnaces with a very basic setup that isnt too busy either and it will work without me ever needing to see it again, meanwhile arc furnaces take up so much room for all the extra stuff you need alongside it in addition to the normal inputs and outputs of resources, doesnt help they DEVOUR graphene even while ice cold at a rate that doesnt make using arc furnaces feel remotely feasible
My personal solution is get rid of graphene as a "fuel" source and instead have it be part of a high tier craftable like a motherboard or something (i.e. 3x Honeycomb Graphene + 1x Glowy Transistor +1x Caramel Brass + 1x Tungsten), and high tier machines would need at least 1 motherboard so graphene isnt just instantly obsolete
