Buildcraft Laser

[Rayancaleb]

Hi,

The assembly table and laser of Buildcraft has always been kind of confusing (and annoying for me) but what I always wondered was, does adding more lasers to an assembly table cost more MJ or does it only speed up the crafting process by consuming the amount of MJ faster?

Please help.

I didn't find the right solution from the Internet.
