Yeah, that's my next project. Currenly I'm in the startup-phase
So I build one yesterday. Well, I think I'll just be building craptons of boilers and lasers from now on because damn, that's some nice yield! What's also nice is that during the night it dug up almost a stack of emerald ore which I had a HUGE shortage on. This means I can now just build whatever filters I want and tune them to whatever I need. Heck, I can have different lasers for different ores and turn them on/off depending on what I need automatically.
I build 4 64x64 quarries but I don't think I'll need those anymore.
