Might be just me, but I cannot actually create them on person or in an assembler and using commands for "loader-furnace" does not work.

Looking at the lua, the recipe reads this:
{
type = "recipe",
name = "lf-furnace-1",
ingredients = {{"steel-plate", 15}, {"advanced-circuit", 1}, {"electric-furnace", 1}},
result = "electric-furnace",
energy_required = 5,
enabled = false
},
instead of
{
type = "recipe",
name = "lf-furnace-1",
ingredients = {{"steel-plate", 15}, {"advanced-circuit", 1}, {"electric-furnace", 1}},
result = "lf-furnace-1",
energy_required = 5,
enabled = false
},

Thanks!

// 1.0.2 - Fixed

With console you can create "lf-furnace-1", this type is for normal speed belt only (the yellow one).

so how exactly does this mod work, because this makes no sense as their is no manual or even a forum thread on it.

13.15 i cant see the loader anymore, can you update it?

Mod is ok. Try to reset this two technologies.
