How can I kill the Erchius Horror after spawning it manually?

I spawned it with the intentions of killing it but then I realized that normal weapons do not work. Is there a command to spawn the canon that can kill it?

 

/spawnitem lunarbaselaser

(after enabling /admin)

I don't think the laser itself is what causes it though, the laser has wire outputs which I think are what actually cause the crystal to die. (This is just a theory)
