Buildcraft lazers

[Norman1346]

Is it the intended functionality that buildcraft lazers consume MJ even when not crafting anything in the assembly table??

I have determined that this is happening for sure in my game. I don't remember them having a constant power bleed before.

Yes. BuildCraft is designed with conservation in tedious bullshit in mind, so the tedious bullshit that was removed because power pipes no longer explode had to be made up for elsewhere. In this case, all BC machines now have a constant power draw, even when not in use.
