Help with gates

[Sample_txt]

I'm trying to run an automated self-shutting laser assembly by utilizing a souped-up electrical engine to power 3 lasers. I've been trying to experiment with gates so that the lasers will always run blue, but when there is nothing to build on the table, the engine will be shut off instead of blowing up my conductive pipe from the buildup of excess MJ.

Is there a way to do this?

Use Redstone energy conduits as they never explode.

Alternatively you could try setting up the gate on the assembly table itself, then 'has word -> red pipe signal' on the gate. I haven't tested that, but as long as the gate recognises the assembly table has work to do, it should work fine.
